Mazda Demio Topping Theft Lists

The Mazda Demio (also known as the Mazda 2) has been making headlines as the most stolen car in New Zealand.

I’m not going to link to any of the usual over-hyped crap reporting outlets, but it’s a big enough problem for the Waikato Police to issue a warning on their Facebook Page back in February.

I suggest checking the NZ Police stolen vehicle page where you can download the number of stolen vehicles for each area if you want some solid numbers.

Anyway now seems a good time to point out what security the Demio comes with and what options there are to protect them.

First off do not assume that your Mazda Demio (or any Japanese car for that matter) has an immobiliser, even if you have a remote key.

Mazda Demio Immobiliser?

I’ve worked on models as late as 2011 that have keyless entry but no factory immobiliser or alarm.

How can you tell if your Demio has an Immobiliser?

Have a look at your instrument cluster and see if it has an immobiliser warning light that flashes when the key is not in the ignition.

All of the generation 3 models (DE) 2007-2014 will have a spot for the immobiliser light. Even cars without an immobiliser have the symbol there but it does not flash! If you look closely you can normally spot it but note that it is not lit up.

Adding an Immobiliser

I recommend the Autowatch 573PPi transponder immobiliser as the easiest affordable option. The Cobra 8510 is also available if you don’t mind using a touch key.

Remote Upgrade Alarm Systems

There are a number of options for the Demio so I suggest contacting me with the vehicle details and I can email the most appropriate options for your needs.

I’ll need to know:

  • Year of the Demio.
  • If the car has a factory immobiliser or not.
  • How many Mazda remote controls you have assuming if you wish to continue using them, or if you’d like an alarm with its own remote controls.

CAN-BUS upgrade alarm (works with factory remote)

The CAN-BUS system on the Demio is similar to most Nissan models in that a manual lock/unlock combined with the hazards lights generates the same data as a remote lock/unlock. This can be used to trick most alarms into disarming! Therefore the only CAN-BUS system I’d recommend is the Cobra AK4615 which is protected from this.

A Cobra Remote can also be added to the AK4615 so if you only have one remote key and a none remote key this could be a more cost-effective option then getting another remote key from the dealership.

Ultrasonic sensors come as standard with the Cobra which protects the cabin along with door, boot and bonnet protection. The Wireless siren can be hidden, plus is loud with horn wired up too so it’ll get noticed if someone does break-in.

Here are some photos of what the Cobra AK4615 alarm looks like installed:

The AK4615 also works the New 2014 Mazda 2:

Mazda 2 DJ 2014-

Most of the new Mazda 2/Demio (DJ) models from 2014 come with a factory immobiliser but still lack an alarm.

The Cobra AK4615 CAN-BUS alarm is the perfect upgrade alarm for these too.

Older Demio?

I’ve got both the DW Gen 1 Demio (1996-2002) and the DY Gen 2 Demio (2002-2007) covered too so please contact me if you need options for either.

    Hello Julian.
    Wow such an eye opener . Thanks for shedding light on this complex problem for some of us. My mum has a Demio (she is older and fits her walker in the back ) One has already been stolen. We are in Tauranga and a bit a a drive to you. Do you know if anyone local that could help with ideas for securing her 2005 Demio?
    Thanks for your help.

    Hi Sean,

    I don’t have a list of installers (mainly because there are not many good ones ? ) so can’t make any recommendations as explained here:
