Toyota Ultrasonic Switch

Back in 2016, I was given the heads up that the Cobra AK4218 Toyota upgrade alarm was going to have one final production run. I purchased a bulk load of them which has got me through the past couple of years.

Well, I’ve finally sold the last one. This means I am no longer able to offer Toyota alarms that can turn the Ultrasonic sensors off with a second press of the remote.

The good news is I have had time to come up with a nice solution.

Ultrasonic Off Switch

New switch for disabling the movement sensors

I’ve had some switches made up that will work with both the Cobra AK4615 and the AK4698. They will fit in most Toyota models from the past 15 years or so where a switch blank is available. The LED in the new switch can also double up as the alarm LED which is a nice touch.

How does the switch work?

Simple, it latches on and off. If pressed in it turns the ultrasonic sensors off and the siren chirps 3 times to let you know. Great for those times when you want to leave a window open. It’s much easier than using the LED over-ride switch.

I’ve also been working with Vodafone Automotive sniffing the CAN-BUS data for Toyota windows. This means it should be possible to have the Ultrasonic sensors deactivate if a window is left open on some of the new models coming out.

New Toyota Hiace Alarm

Back in March, I got my hands on the new 2019 Toyota Hiace (H300) to test out the factory security system. It’s quite a change from the old model and comes with an alarm system.

I’ve now installed well over 400 alarms in the old shape Hiace. Given the popularity of the van, it has been a priority to make sure I had a solution for the new model as soon as it was available for sale.

Is the Factory Alarm any good?

Well, it works from the factory remote key and it covers the doors, boot and bonnet.

It also disarms with the driver’s door lock!

The 2019 Hiace

What does the Toyota Hiace alarm lack?

The alarm lacks internal movement sensors and will disarm if the door lock is picked. Given this, I highly recommend upgrading if you keep any valuables inside.

Upgrading the Hiace Alarm

I have been busy working with Vodafone Automotive developing the AK4615 CAN-BUS alarm firmware to work with the new Hiace. I’ve also gathered all the wiring information to make the installation as clean as possible.

The AK4615 works with the factory remote. It will not disarm when the door lock is picked, has a super loud digital battery back-up siren and honks the horn. It also has ultrasonic internal movement sensors so covers all bases.

LED over-ride

The Alarm comes with a red 3mm LED mounted with the over-ride switch. I the Hiace I fit it next to the traction control button as shown in the photo below. For anyone wanting a brighter LED, I can easily add one.

Easy Emergency Over-ride 

The PIN code over-ride can be customized to any 4 digit number so the alarm can be disarmed if the remote battery fails.

Note that the New Hiace is not being sold in Japan so there will not be any used Japanese import models coming over.

The old shape Hiace is still being sold by Toyota NZ. Details about the alarm options for the H200 shape Hiace ca he found here…

Optional Upgrade:

Tilt Sensor $150.00

I’ve not yet come up with a courier alarm solution but dare say I may get around to that once there is a demand for it.

Selective Unlocking

Selective Unlocking simply allows you to select which doors you unlock. It’s a common feature on many new vehicles.

Ford Transit Remote offers Selective Unlocking

Most systems unlock the driver’s door with the first press of the remote unlock button. A second press will then unlock the other doors.

Some vehicles like the Ford Transit have a dedicated remote button to select which zone of the van unlocks. This way it is possible to unlock the back of the van and leave the front locked.

Many vehicles allow you to turn this feature on or off to suit your requirements. Take my Nissan e-NV200 for example, selective locking can be turned on or off by holding the lock and unlock buttons together for a few seconds. Personally, I like all the doors to unlock with just one press of the remote.

Aftermarket Selective Locking

Selective locking can be retro-fitted. The video below shows an install I did on a 2009 Toyota Landcruiser which did not have central locking before it got into my hands.

My customer asked if it was possible to just have the front doors unlock with the first press of the remote. No problem as the Cobra AK4698 supports selective unlocking.

Systems that support Selective Unlocking:

Other Options

If you want selective unlocking from your factory remote and your vehicle does not support this I can probably use a Double Tap Module to make it possible.

Ford Transit Cargo Alarm

I got my hands on a 2019 Ford Transit Cargo this week. That’s the big brother to the Transit Custom.

My first job was to test the factory central locking to see if the van had the updated firmware. In the past, the factory alarm would disarm if and the rear doors would unlock if the driver’s door barrel was picked! So much for deadlocks hey!

The good news is that this issue seems to have been fixed. I don’t think Ford NZ have any interest in updating the firmware on older vans, but hope I’m wrong about this. They failed to get back to me when I contacted them about it last year 🙁

I do have my own fix for this for those who don’t get any help from the Ford dealership.

Ford Transit Cargo Alarm

Is the factory Ford Transit Cargo alarm good enough?

Well, it has door boot and bonnet protection and honks the horn, but offers no internal movement sensor. You may want to consider an upgrade if you keep valuable tools in the back.

Making the Ford Transit Secure

My recommendation is the Cobra AK4615 CAN-BUS upgrade alarm which works with the factory remote. It has a super loud siren and honks the horn so is much louder than the factory system.

The AK4615 comes with Ultrasonic movement sensors as standard to cover the cabin area of the van.

I recommend adding a PIR sensor to the back of the van to cover the load area.

Here are some photos of how the alarm looks after the install:

Nissan Leaf Upgrade Alarm

The Leaf came out in 2010. It is the first fully electric vehicle from Nissan and accounts for about 50% of all electric vehicles in New Zealand.

Being an e-NV200 owner I am well aware of how many are on the roads. In my eyes, they are a nuisance as they block the charging ports when I need a top up 😛

I also remember being jealous that the Nissan Leaf had a button on the remote to open the charge port. Sadly this was not carried over to the van. Nissan decided a shitty bonnet pull lever would do! Of course, this simply inspired me to find a solution.

Nissan Leaf (ZE0) 2010-2017

What security does the Nissan Leaf come with?

The Leaf comes with a factory immobiliser and SmartKey entry with push-to-start.

Most don’t have an alarm, the ones that I’ve seen that do have chunky black ultrasonic sensors on the “A” Pillars. I think the alarm was a dealership fit option when sold in Japan, but I’m not certain about this. If you are a Leaf geek feel welcome to confirm or correct me on this.

For those that don’t have an alarm and want that extra level of security, I highly recommend the Cobra AK4615 CAN-BUS alarm for Vodafone Automotive. It works flawlessly with the factory SmartKey.

Nissan Leaf SmartKey with charge port open button

The AK4615 offers a super loud digital siren, horn honk, door, boot and bonnet protection, along with ultrasonic internal movement sensors.

The Sensor pods come in grey as standard which is a perfect colour match for the 2010-2012 models which have a grey interior. The later models have black “A” pillars. The sensor pods can be painted to match.

Below are some photos of how the alarm looks when installed:

I’ll post an update on the New ZE1 Leaf soon.

I’ve also been doing some CAN sniffing on the Leaf as well as my e-NV200. Hopefully, I’ll be able to offer KEYLESS BLOCK for it soon. Watch this space…

KEYLESS BLOCK from Author is designed to protect vehicles with keyless-start from Relay Amplification Attacks.

Before explaining how KEYLESS BLOCK works I’ll explain how SmartKeys work and how they are vulnerable to a Relay Amplification Attack:

How a SmartKey works

Many modern vehicles have a SmartKey which allows you to lock, unlock and start the vehicle without touching the key so long as it is in proximity.

When the car door handle is touched the car sends a challenge to the SmartKey. The SmartKey (if in range) will respond by transmitting a rolling code unlock signal, just like pressing the unlock button on a traditional car remote. This is known as a “Challenge and Response” and will only unlock the car if the SmartKey is programmed to the vehicle and is in range. The range is typically no more than 1 meter from the car door.

Relay Amplification Attack

A Relay Amplification Attack tricks the vehicle into thinking the key is in proximity. It involves two people.

One stands by the vehicle and touches the door handle, they use a gadget to extend the challenge signal to the second person, also with a gadget which will receive the challenge.

Person number 2 needs to be close to the SmartKey so will stand by a window or front door of your home to get in range, or maybe stand by you if you have it on your person. Once the SmartKey responds the unlock signal is then extended back to the first persons’ gadget which unlocks the car. The car can then be started using the same method once the start button is pressed!


KEYLESS BLOCK arms when the vehicle is locked, either with the remote button or using the keyless system.

It shuts down the keyless function of the vehicle locking system to prevent a Relay Amplification attack.

KEYLESS BLOCK can disarm in a number of ways. Pressing the unlock button on the SmartKey will disarm the system and the vehicle can be used as normal.

Then there is the option to program the system to disarm from an external device, such as a remote start or GPS tracker.

Disarm KEYLESS BLOCK via Bluetooth


The system also comes with two Bluetooth Fobs which will restore keyless access when in range.

It can also be paired with a Smartphone to work with the Author ID App via Bluetooth.

The range of the Bluetooth Fobs and the phone can be adjusted with using the AUTHOR CONFIG App.

When a paired Bluetooth device is in range of the vehicle the full keyless functions are restored.

Service Mode


The CONFIG App also allows you to put the KEYLESS BLOCK into service mode.

Service mode turns the system off so that you can have the vehicle serviced without the dealership knowing you have it installed.

The KEYLESS BLOCK can also be put into service mode without the App.

This is done by turning the ignition on (without starting the car), then pressing the accelerator pedal 5 times.

To take the KEYLESS BLOCK out of service mode the same procedure is done but the accelerator pedal is press 4 times.


A list of vehicles that KEYLESS BLOCK works with can be found on the IGLA NZ website.

More vehicles will be added in time and I’ve been involved with the process of developing the firmware for some vehicles.

I’ve already mapped my Nissan e-NV200 van to work with KEYLESS BLOCK by sniffing the CAN-BUS data, then sending it to the technicians in Russia who have written the firmware for it. (I’ll explain more about that in the future)

Iveco Daily Upgrade Alarm

Iveco Blog Posts

The Iveco Daily I recently worked on was first registered in 2019, however, looks to be to older shape model made between 2011-2014.

Regardless of production dates, all models come with keyless entry with selective unlocking as well a transponder immobiliser. It does not have an alarm so I if you keep tools or valuables inside then it’s worth considering.

I highly recommend the Cobra AK4615 CAN-BUS alarm for both the pre and post-face-lift models as it works flawlessly.

Iveco Daily Alarm Install

Iveco Daily Alarm

What you get:

A tidy install that works with the factory remote control, a very loud siren that is hidden and horn honk so it’s a distinctive sound.

Bonnet Switch

There is no factory bonnet switch on the Iveco, so I used a custom bracket and waterproof switch. This mounts neatly on a factory bolt so there is no need to drill a hole.

Here are some more photos of what you’ll see after the install:

Parallel Import Cobra Alarms

One thing I have always loved about Cobra NZ is that they have always been selective who they sell their products to.

Unlike most other vehicle security brands it has always been about quality as opposed to volume.

Being a security product you probably want to know that you have a competent trustworthy installer, great product reliability and strong after-sales support.

This is part of the reason I believe they have such a great reputation in New Zealand.

I work with Cobra NZ on a regular basis. The technical support I get is second to none. I’ve even had some training in the production plant based in Varese, Italy.

Parallel Import Cobra Alarms? Good or Bad?

Parallel Import Cobra Alarms

It has recently come to my attention that a Company in Lower Hutt has been Parallel importing Cobra Alarms. Whilst there is nothing legally wrong with doing, I still have some moral objections to the practice.


I think that it should be made clear if you are selling Parallel Imports rather than simply not mentioning that you are not an approved dealer! It’s about being honest and transparent. Personally, I believe this is vital if you are dealing with security products!

Speaking of being honest the company in question has had some shocking Facebook reviews in the past. I recall one relating to a scratched dash trim where they failed to respond to the customer. I checked their page out before writing this and noted that reviews are no longer visible!

Am I to assume that any company who does not allow reviews to been seen on Facebook has had poor feedback? I’m guessing Facebook allows this because they still want the advertising money! Anyway getting back to the subject…

Why Use an official Cobra Dealer?

First off using an official Cobra dealer helps protects you against poor workmanship. It’s vital that the installer knows the product, has full technical support and access to firmware updates and installation documents.

I’m always ranting about how bad most alarm installations are along with how many dodgy installers are out there! I’ve spent years building a good reputation for both myself and Cobra NZ. I’m not happy when I see Cobra alarms poorly installed.

After Sales Support

As a Cobra dealer, I am required to register every alarm that gets installed. This way there is a record of it should there be a warranty claim, or if replacement parts are needed.

For example, let’s assume the vehicle has changed ownership and both remote controls are lost. It’s vital that there is a record of the alarms over-ride pin number. Without this, the alarm will need to be removed and will probably end up in the landfill!

I could continue but you’ve probably got the point by now. On the bright side, the alarms do appear to be genuine, which is more then what I can say about what is happening in Australia!

Do you Recycle your Remote Batteries?

How many small batteries do you go through each year?

I know I get through a large number, especially the small coin batteries that most car alarm remote controls use.

What do you do with the dead ones?

Do you place them in the rubbish bin? Or do you go to the effort of recycling them?

Do you even know where you can take them to be recycled?

My battery collection which I recycled today

Today I dropped a box full of small batteries off at the Sustainability Trust in Wellington. They do charge a small fee to cover their cost, but it’s not much.

The box above cost me $2.50. Yes, it costs more than putting them into the rubbish, but its the right thing to do, well unless you are a thoughtless arsehole!

Sustainability Trust in Wellington.

I asked if they would still charge if I only dropped off a couple of batteries. The reply was no, simply because it’s not worth the admin time, and they would rather take them than know that they would otherwise end up in a landfill.

Recycling Challenge

Now I’m not perfect and know I can improve my recycling game. In doing so I encourage all of you to do your part too. Feel welcome to give me your used batteries if you see me out and about. I keep a box for them in the van. Or better still recycle them yourself.

Challenge the shops that sell batteries

Next time you go into Jaycar, Repco, Super Cheap Auto, or your local car dealership to get new remote batteries ask them what the do with the old ones.

Do they recycle them? If not why not?

Ask the same question to your local car alarm installer too. They may not even have considered recycling them, so your question could make the difference.

Let me know what the reply is. Feel welcome to publish it here too.

If you live outside of Wellington let me know where you take your batteries and I’ll update this post to make it easier for people. Everyone who makes an effort will make a little bit of difference so please encourage responsible recycling habits.

Thanks Julian

Shock Sensors and False Alarms

Watch out for the Fat Man in a Balaclava!

Shock Sensors are beyond doubt the main culprit when it comes to false alarms.

How many times have you got annoyed at a car alarm going off for no obvious reason?

More to the point, have you ever gone out to check and see if your neighbour’s car is actually getting broken into? Let alone catching a man in a balaclava hitting your car like an imbecile?

Don’t cry wolf!

If you think that getting an alarm with a shock sensor is a good idea then watch this video:

How do Shock Sensors Work?

Magnetic Shock Sensor

The most common impact sensor is the magnetic shock sensor. It is simply a magnet held by an elastic band which is suspended next to a coil. When the Magnet vibrates it induces electricity in the coil. This, in turn, triggers your car alarm to go off.

Sensitivity Adjustment

These sensors have a sensitivity screw which can be dialled up and down. This is used to adjust how much vibration is required before your alarm sounds. Some have a dual zone setting.  The 1st zone being more sensitive will tell the alarm to chirp a couple of times as a warning should a small vibration be detected. The 2nd less sensitive zone will trigger a full alarm.

Other types of impact sensors

There are other other types of shock sensors out there which I’m not going to explain here (piezo sensors for example). These sensors need more understanding of electronics so are not going to make sense unless you are into it. You can do your own homework if you really are interested!

What you should know is that all shock sensors deliver similar results. They pick up vibrations to set your alarm off.

Why have a Shock Sensor?

The reason many people think they are a good idea is that they don’t want their car’s bodywork to get scratched or dented. The reality is that constant false alarms piss everyone off will probably be the motivation to actually take a key to your paintwork!

The irony is that the act of keying a cars paintwork is unlikely to be picked up by the shock sensor!

It’s also unlikely that the use of a screwdriver to remove your number plates or exterior accessories will be detected by the shock sensor.

Here is a quote from the Mongoose installation manual:

Avoid over sensitivity as people nearby may not respond due to too many false alarms. (This type of sensor may not prevent wheel theft, we therefore advise the fitment of locking wheel nuts)

So what will cause a shock sensor to trigger?

There are many things that can cause the sensor to vibrate. The environment the car is located is often a big factor. For example, a car parked in a multi-storey car park is very susceptible to the resonating frequency of motorcycle exhausts, or even loud car exhausts for that matter.

Cars parked on the roadside can pick up vibrations from trucks and buses passing. In Windy Wellington, the wind can also play havoc with them.

The location of the shock sensor in a vehicle is also a major factor. In theory, the best location for one is the centre of the vehicle so it is not biased to one side. Yet most of the ones I have removed are tied to the steering column!

So why do so many alarms come with Shock Sensors?

First off is that they are cheap to manufacture. Secondly is a false notion that they will protect your car from getting damaged. The reality is there is not much that can be done to protect the outside of your vehicle without false alarms. If you want to protect your wheels then a tilt sensor will be far more effective.

What about Intelligent Shock Sensors?

I have read all sorts of marketing bullshit about “Intelligent” shock sensors. Some alarms have them built into the brain which makes the ideal centre of the vehicle location impossible in most cases!

The reality is that a car thief is not going to bang on your windscreen to set it off. But I do know if a case where an installer has cracked a windscreen doing this test!

Intelligent hey!
