Immobiliser Removal

Over 90% of aftermarket security systems that I come across take less than 5 minutes to remove, making for an easy immobiliser removal and bypass.

I’d love to say that this was due to how skilled I am in the dark art of car electronics but the truth is that it is down to sloppy installation.

Generally, I find that the best-known brands are the easiest to get past. I’ve lost count of how many AVS and Mongoose alarm/immobilisers I’ve removed.

The quality of the installation from most of the car audio shops is shocking

Immobiliser Bypass

Normally all I have to do is remove the trim below the driver’s side dash and hey-presto, the alarm module is placed behind waiting to be bypassed!

Some are held by a cable tie and others simply fall onto the floor as shown in the photo below! Then it is a simple task to open the case and bridge the immobiliser points. Car started…

Immobiliser Removal

Easy to remove!

Why most Immobilisers not effective?

The main reason is the installer, the system is only as good as the installation. It takes more time, knowledge and skill to install an immobiliser effectively.

If the module is easy to access then it is quick to bypass.

A smaller Immobiliser gives the installer more options as to where he can place it. Therefore, it is a good idea to chose one that is not too large and better still one that is not easy to open up!

Don’t be cheap!

A large percentage of immobilisers are installed at car yards where the main motive to have one installed is profit for the salesman rather than to actually secure the vehicle.

Where the purchase is driven by price most people will choose the cheapest immobiliser and installer. Obviously, this is likely to result in a quick installation, hence why I find most systems so quick to remove.

Please Note:.

I do not offer free technical support and will not hand out information on how to bypass security systems as I’m not here to aid in car theft! I also need proof of vehicle ownership before I remove a security system.

Note: I only cover Wellington so if you need to use my services then bear this in mind.

    Im currently trying this at the moment…as my car randomly turned off on the motorway whilst doing 100khm…and when i pushed alarm mobilizer, nothing happned…this is verry usefull info cheers… hope it works for me:(

  4. Julian says:

    Let me know how you get on, or if you need any help then give me a call after the 28th (I’m in the USA right now)

  5. Brendon says:

    Hey mate, our imobilizer only woorks when it feels like it so every time we jump into the ride it takes 10-15 to get it up and running. do you have any step on removng this imobiliser that you could send me as I’m in rarotonga now so I would prefer to remove it myself as it costs two arms and a leg here

  6. Julian says:

    Hi Brendon,

    I’d probably be looking at why it takes so long to disarm. Is it a remote immobiliser, a touch key or a transponder system. Most systems have an over-ride number which I assume you don’t have. Some basic info on the make and model of the immobiliser would be useful, plus it would help to know what vehicle it is in.

    If you’re not confident with vehicle electronics then I suggest you find someone who knows what they are doing.

    Hi, I have a toyota levin with a meridian immobiliser fitted in it. I got the car 2 months back and the previous owner dint leave me any code and the remote was old enuf not to reveal any info abt it. now my remote is broken. I d like you to suggest if I should get a new remote for it or should I take out the alarm? and which one would work out cheaper? if I have to get a new remote where can I get one in Auckland and how much would it cost? cheers!

  8. Julian says:

    Given that the point of an immobiliser is to make the car difficult to hotwire and that the Meridian fails horribly at doing this (not helped by how inept most Meridian installers seem to be), I’d suggest replacing it.

    Price will depend on who you deal with, however don’t complain if you get a crap install and service if you’re after the cheapest!

    You can contact Meridian on 0800 731 173

    Hi I have a 91 Nissan primera with a dynatron immobilizer alarm. It stopped working I flicked the key on to dash lights as forgot over ride pin.. it did some funny clicks and intercators pulsing. Turn ignition off went inside. Later go to car it is completely dead jump start battery.. don’t need to use immobilizer pad but drivers side indicator lights stay on but not blinking just solid light. Have to disconnect the battery terminal

  10. Julian says:

    Make sure that the battery is fully charged before you reconnect it. Car electronics can do all sorts of strange things if the voltage is to low.

    If this does not work then get an alarm specialist or Auto sparky to look at the car for you.

  11. Katie says:

    Hi , my mum brought a ford laser a few months ago and she went to start her car yesterday and nothing , the car turns over but won’t go and we think it is an immobilizer , she contacted the previous owners and they didn’t know it even had an immobilizer so we don’t have any codes . Is there anyway we can turn the immobilizer off so she can get her car started as she has to travel back home .

  12. Julian says:

    Hi Katie,

    What makes you assume that the car has an immobiliser? Most after market immobilisers have an flashing LED to indicate that they are active and to deter any potential thief. Did the car have a transponder tag which has now been lost? Or has the key been lost and you are not using a none coded one? or have you you any other reason to draw this conclusion?

    There could be all sorts for reasons why the car does not run, from a blown fuse (common if the car has been jump started the wrong way) or electrical issue, to a faulty ignition coil or even an empty fuel tank.

    If you are not familiar with cars and trouble shooting then have someone look at it for you.

  13. haley says:

    Hi I have a nissan skyline 350gt we got car home from sales yard and just realized it has buttons on the outside of the car to unlock it without keys or anything, use our remote and locks but push button on outside and boom your in the car.
    any help on this would be greatful

  14. Julian says:

    Hi Haley,

    You have a proximity remote or smart key as they are also known as. The car should lock and unlock by pressing the button on the door only if the smart key is in range.

    How it works: There is a sensor in both of the front doors and sometimes the boot too that turns on and looks for the smart key when you press the button on the car door, if it is an range then the doors will lock or unlock. The range is typically about one meter from the door handle. The idea being that you do not have to access the smart key and it can remain in your bag or pocket.

    Place the smart key away from the car and the button should no longer unlock the car.
    You’ll also find that the car will not start if you don’t have the smart key.
    How many keys do you have for the car? It’s a good idea to have a spare as it’ll be a big issue if you lose your only working one.

    Silly question but why did the cars salesman not explain this when he handed the keys over?

  15. Pauline Pakinga says:

    Hi how would I remove a system from a Ford Falcon xrd. Cars been sitting for a month now as it won’t start, powers on but nothing after that and the flashing icon is continuous we have one coded key

  16. Julian says:

    Hi Pauline,

    That’s a job for a good Auto Electrician or the Dealership. I’m not going to help a car thief get information on how to by-pass a factory immobiliser on a public forum.

  17. Jennifer says:

    Hiya! Unsure whether this is an immobilizer issue but we have no spark to ignition coils or the whirring noise for the fuel pump. Turns over but won’t start.
    Lost and duno what to do.

  18. Julian says:

    Hi Jennifer,

    If you’re in Wellington then I can take a look at the car for you.

  19. Bob says:

    How Hard is it to remove a Blackhawk system?

  20. Julian says:

    Hi Bob,

    That all depends on how will it is installed and how competent the person trying to remove it is.

  21. Paewai says:

    Hi mate I’ve got a avs alarm imobiliser my remotes both stuff out I have cut the wires that were wired to the ignition and wired the ignition back to were it was bfor alarm got put in its starting but no one home like it not fireing up I take it I have to do something else todo with imobiliser can you help me out please as I love our country and nearest town 60km away

  22. Julian says:

    The moral of the story is that it’s a good idea to know how your alarm works before it’s to late! Sounds like you still have a immobiliser cut you have not found, a well installed immobiliser should not be easy to by-pass otherwise what is the point in having one?

  23. Cynthia says:

    Hi I recently purchased a second hand vehicle through a private sale its got an aftermarket immobiliser in it but now the remote is buggered I’ve tried a new battery the light on the remote goes but it is still not enough to trigger it off, the lights on dash light up but doesn’t start the vehicle up so now I’m getting a bit pissed off and just want to get the whole dam.thing off!!! Its a 2002 Nissan Pressage, auto,2.4 can u shed any light on the situation

  24. Julian says:

    Hi Cynthia,

    There is not much I can do without seeing the car.
    If you are in the Wellington region feel welcome to give me a call to arrange a time to look at it.


  25. Waiari says:

    Hi, I have a 2005 Toyota bb on finance and if I miss a payment for whatever reason the finance company disables my vehicle and I am unable to start it until payment is made. May I please ask how I may go about this issue or in other words (how to start my car even though it has been disabled by finance company?)

  26. Julian says:

    Hi Waiari,

    What you are asking me to to is to aid and abet with theft of a vehicle!!!

    If the car is on finance then the finance company legally own the vehicle until it is fully paid for. Therefor they have every right to activate the immobiliser if you have defaulted on payment.

    I hate thieving bastards and am not about to help you become one!

  27. John says:

    Hi, I bought a 1996 honda accord LXI, and I was wanting to get an immobiliser in my car. The boot of my car can be fully locked, requiring the key to actually get in, as the back seats will not fold without the key, nor will the boot open without a key. I was wondering if an immobiliser could be installed so that it can sit in a place in the boot, so it will not be bypassed so easily.

  28. Julian says:

    Hi John,

    (delayed response due to being on holiday)
    Most immobilisers are small enough to hide with other electronic components in the vehicle and I always install them in such a way that they are not easy to by-pass.
    If you are keen to get one then fill in the contact form so I can go into details without making your details public.


  29. Leesh says:

    Hi have bought Honda rafaga 94 second hand was running good for a week then immobiliser started cutting the engine n now it won’t start all lights turn on etc it didn’t come with any remotes n we were not told bout the alarm or immobiliser how can we get the car going again

  30. Julian says:

    Hi Leesh,

    You’ll need to book the car in for me to look at. There is not much I can do without knowing what make of immobiliser you have or being able to see the car.
    Use to Contact form rather then make your details public

  31. Leesh says:

    Hi the make of alarm is steelmate i couldnt get into the contact page but if u hve a number to call or email i would really appreciate it

  32. Jo Jo says:

    Hi i have a 1992 mitsubishi lancer that has a avs a4 alarm in it , ive lost the alarm. any idea how to disable it so i can start it please. 0212679631 is my number if u could throw a text .

  33. Julian says:

    Hi Jo Jo,

    If you are based in Wellington then you can contact me during business hours and book your car in. If not then contact AVS for support. I don’t hand out this information without verifying that you are the legal owner of the vehicle, I also have a business to run and my time needs to be paid for.


  34. james says:

    Hi I bought a 96 Rover 825 sli the people I bought it off sold it in an immobilized condition and they had no code for it. I got in touch with Rover UK They had no code for it either maybe too old. Rover NZ have a remote they called it a blank. They say that a company who specialize in car alarm’s and in immobilizer’s can computer it to the system on the Rover. My question is. Is that possible. thanks.

  35. Julian says:

    Hi James,

    I specialise is aftermarket security Systems, not factory installed ones. I don’t know why Rover NZ would suggest that a business they have not had any dealing with would have access to their systems. Why not simply let Rover NZ deal with it?

  36. Helen says:

    Hey mate,

    I recently scored a 95 Nissan Sentra hatchback, primo little runner etc. After a week of enjoying it the bloody thing cut out on me and it’s currently parked in a place where I’m getting tickets daily by the council ?? it has a uniden car alarm/immobiliser installed in it (god knows why) and I’m only getting the reds at the moment, it won’t click over to start? I’m not in the know nor do I have the money to get an auto electrician to come fix this problem for me. People have offered to disable it for me but I have a trust issue with street mechanics! Any advice on what to do would be much appreciated!


    Hi i have a 2007 Volkswagen Eos the immobiliser is staying on ie cant start car would i need a key code to overide it, the batteries have been fully charged they were below 6 volts
    Any help would be appreciated

  38. Julian says:

    Hi Vaughan,

    I assume you are referring to your car battery (although you are using the plural version which suggests you have more than one?)

    Factory immobiliser systems use a transponder system that does not require an over-ride.
    I suggest making sure your battery is OK or contacting the AA or dealership.

  39. Robert Richmond says:

    Hi there I recently bought a second hand Mazda 3 it came with an auto watch 555 immobiliser/ central locking system. I it works with the factory key fob and there is a code. I have the code but don’t know where the hidden button is or the device where I need to key in the code. My question is where is the most common places to hide the button?
    Thanks in advance for all your help

  40. Julian says:

    It all depends on who has installed it (if at all). My guess would be as good as yours.

  41. Sean Morrissey says:

    Hi there my immobiliser works now and then. When it wants to. Not sure what’s up. It’s not part of the key fob it’s it’s own separate system. Happy to send a photo if you have an email address.

    I am wanting to get this sorted so I can use my car. Any help would be appreciated.

  42. craig davis says:

    Hi I live in the South Island I put my car into a mechanics to have engine mounts replaced.
    They disconnected the battery and some how activated the immobilizer, car turns over but no start. Nissan Teana 2005. Car has been taken to Nissan after two weeks they failed to get it working. now car is back at garage. i just need my car back any ideas to bypass immobilizer. Garage want to make me pay for it to be fixed but don’t know what the problem is I believe it is anti theft system. I need help please. family car less

  43. Julian says:

    I can only guess as I’ve not seen the car or worked on it! Rule number one with diagnostic troubleshooting is not to jump to conclusions.

    What makes you believe it is the immobiliser? From my experience, it is extremely unlikely that the immobiliser is the cause of the issue as they are normally very reliable. It could be something very simple like a component left unplugged, a blown fuse, or even a damaged wire that prevents the engine from running!

  44. Craig Davis says:

    Thank you for your reply It is the stock factory nissan teana 2005 immobilizer j31 setup. But I have now had the AA drop the car home. I will look to see for any of your suggestions fuses plugs wires etc. But the keys returned to me have now have been deactivated as in won’t work on the car. I’m so gutted. Failing all this either 1k for another bcm with no guarantee it will fix it.

  45. Anita says:

    Hi I have a 2005 Toyota hilux with a security mobiliser in it lost my key my key had the chip in it to start my truck how can I take my mobiliser out so I don’t have this problem at all I don’t need it I just want it to be a normal start up thanks any help will be much appreciated I’m in the king country area

  46. Julian says:

    As stated in the post, I don’t give out info on how to breach security systems. You’ll need to get the Ute to the nearest Toyota Dealer and get a new key programmed.
    I suggest you get a spare one too as you should now understand what a pain it is when you lose your only one!
