GT86 Alarm Installation


Toyota Blog Posts

The Toyota GT86 is one of those cars that I’ve been itching to work on, so when I got the call from the local Toyota dealer before Xmas advising me I’d have one to work on in the new year I was stoked.

The original intention was to install a Toyota approved Cobra AK4218. I’d spent some time doing my homework and got hold of some wiring schematics for the car and even had a look at one in the showroom to get a good feel for it in advance.


As with all new cars, the first one takes longer to do as it needs to be cracked. I also like to make comprehensive notes as I go so that the next one is much easier. I’d given myself heaps of time on this job to take the pressure off.

There was just one nagging doubt in the back of my mind. How much of this car is actually Toyota? The electrics could turn out to be Subaru so I was not going to take any chances. I took a Cobra AK4615 along as a backup plan!

It didn’t take long to take the dash apart and as I’d expected, the electrics were very Subaru! The AK4615 was going to have to be made to work. Still, this is not such a bad thing as it does have a wireless siren which I soon found a┬ádiscrete location for.

86 is very much a Subaru!

Black Ultrasonics

Most of the current range of Cobra alarms come with grey ultrasonic capsules and for 9/10 vehicles look fantastic, however, I knew the 86 had a black interior so painted the ultrasonics black in advance. They sure looked the mutts nuts in matt black ­čÖé

Smart Keyless Entry

The GT version of the 86 has proximity keyless entry which unlocks the doors as soon as your hand reaches behind the door handle (assuming to remote is in proximity). The alarm was wired so it disarmed with the smart proximity unlock as well as the remote buttons.

As with all good upgrade alarm installs I made sure it was not possible to arm or disarm the alarm by forcing the door lock or by pressing the lock/unlock switch on the driver’s door.

Finally, I found a neat location for the LED over-ride switch opposite the Start button in the centre console.

The result was a very stealth install and another car to add to my database. I’ve also drawn the conclusion that the 86 is more Subaru than Toyota!

Update: Since this install, the CAN-Bus software has been released for the Cobra AK4615.

    Hi Julian,

    I have a toyota 86, not the toyota gt86. The toyota 86 uses a smart key but not a smart keyless entry. What upgrade alarm is best of my car ? is the Cobra AK4615 best recommended for my car? Will the Cobra AK4615 allow me to arm and disarm my alarm using my orginal toyota smart key?

    Oh I forgot to say. I would like you to install my alarm system, but sadly I’m in Auckland and I don’t have the time to go all the way to Wellington due to school and stuff. What is my best option?

  3. Julian Julian says:

    Hi Jonathon,

    Yes the AK4615 will allow you to arm/disarm via the factory remote key. No problem with it being an 86 rather then an GT version as it’s still the same car.

    There are no Cobra installers in Auckland at this stage that I would be happy to recommend, however if you are willing to travel down to Hamilton then Bret at Trends is very capable.

    Your other option would be a Autowatch 695CAN. Whilst I personally prefer the Cobra it’s still a good alarm.

    Hi there,

    Since the cobra ak4615 has two ultrasonic, in the picture, i can see that the ultrasonic is placed in the drivers side corner near the door, where is the 2nd ultrasonic placed?

  5. Julian Julian says:

    Hi David,

    The other ultrasonic is on the passenger side. They normally get fitted at the top of both “A” pillars either side of the sun visors.

    Hi Julian,

    I’m just wondering after the installation of a car alarm, am I suppose to keep the programming kit? or is that for the installer to keep?

  7. Julian Julian says:

    Hi David,

    I assume that you a referring to the Antares software programmer for the AK4615? These are only available to selected Cobra dealers.

    It is the role of the installer to program the alarm to your requirements and make sure you have a full understanding of how it all works.

  8. Avatar David says:

    So the Ak6415 can be programmed and adjust to me requirements, what areas can be adjust?

    Thank you for your help

  9. Julian Julian says:

    Arm/disarm chirps on/off, or chirp volume adjusted .
    Anti Hijack options (with optional drivers card).
    Personalisation of over-ride PIN number.
    Window closure, auto/manual select (if installed).

    Some of the options are vehicle dependent and may require extra parts etc.

    If you have any specific requirements then I normally do my best to see if I can make it happen where possible.

    Probably best to give me a call talk about the full list of options, or chat to your local installer to see what they are capable of offering.

    Hi Julian,

    My installer has installed Ak6415 on my GT86, he gave me a cobra manual CD, but I cannot seem to open the files on the disc, not sure why, it doesnt open on any of my computers. I want the car to make sounds when it arm/disarmed. Also when I arm the car, it takes about 45 seconds before its fully armed. Example when i arm the car and instantly open the boot, it won’t trigger, I need to wait around 45 seconds before it screams. Is it possible to make that time shorter?

  11. Julian Julian says:

    Hi David,

    Can I ask why you have not addressed these questions to your installer?
    Surely that would be part of the deal with paying them for the alarm/install?

  12. Avatar David says:

    I have asked my installer, he said hes not too sure and will call and ask cobra and let me know, but he hasn’t gotten back to me yet. My installer was contracted by toyota. I thought I might be able to get answers more quicker from you since you just installed the cobra on the same car as mine

  13. Julian Julian says:

    Here’s the user manual that comes with the CD. Should cover all you need to know.

    As previously stated:

    “There are no Cobra installers in Auckland at this stage that I would be happy to recommend, however if you are willing to travel down to Hamilton then Bret at Trends is very capable.”

    If anyone knows of a good Auckland installer then please let me know!!!!

    Thank you very much

    May I also ask, what is an emergency panel pushbutton? Is that the hazzard red triangle button?

    I’m not sure which company installed the alarm for me, but it was arranged by toyota

  15. Julian Julian says:

    From your description it sounds like you are talking about the hazard switch. Pressing this will make your hazard lights flash to warn others that you or your car maybe a potential hazard! It has nothing to do with the alarm system. Having said that there is an option to wire the AK4615 alarm up so that it will not arm via the remote if the hazard lights are on. I don’t normally wire this option up, but given that I have not installed your alarm it’s probably best to ask your installer if he has.

    The emergency panel is the button with the LED on it.
    Here it is on a Hiace along with a video explaining how it works:

    Can u please explain to me how to turn on the chirp sound when i arm and disarm the car. Thanks,

  17. Julian Julian says:

    Hi David,

    You’ll need to go to your installer to have this programmed.
    I suggest you contact them rather then me, unless of course you’re happy to travel down this way and pay for my time.

  18. Avatar David says:

    It needs to be programmed via connecting it into the computer or is there another way?

  19. Julian Julian says:

    If you’d like to pay for my time and expenses including a return flight to Auckland then $1,500.00 should cover it.

    My Account number is: 38-9007-0649655-00
    I’ll advise you what days I can do and provide you with a GTS invoice upon payment.
