Cobra AK4218 Toyota Upgrade Alarm

Toyota Blog Posts

The AK4218 is an upgrade alarm from Cobra which is designed exclusively for Toyota models that have a remote key. It replaces the discontinued AK4147 and is very similar to the brilliant Cobra AK4198. The main difference being is it works with the Toyota remote rather then a Cobra remote.

The great thing with the AK4218 is how it works. Where other upgrade alarms monitor the vehicles central system to arm/disarm, the AK4218 reads the Toyota remote signal. This makes the alarm able to be more user friendly as a second press of the lock button can disable the Ultrasonic sensors, and a third press can disable the optional PIRTilt sensor, Reed switch or Microwave sensor. Great for those times when you want to leave a window open or take the vehicle on a ferry for example.

The AK4218 comes with the excellent 4310 waterproof battery back-up siren and supports horn honk so is super loud.

The alarm will only work with Toyota models that have a traditional remote key so if you have a model with proximity locking and push to start then the AK4615 would be my suggestion. Alternatively contact me with your vehicle details and I’ll get back to you with some options.

A full list of compatible Toyota models can be found at the bottom of the post.

    Hi can you tell me if this alarm is still available? I looked for it on the Cobra website but it doesn’t look like it’s there anymore….

    I’m after a basic (decent) alarm for a 2005 Toyota Fielder. I currently have a autowatch 446RiSG in my old car and was considering getting it transferred to my new car. But it would be quite cool to have the alarm run off the factory remotes.

    Another question – my car has some smart lock remote which means if I’m close to the drivers door and try to open the car it will open. I guess whatever alarm I install that would need to be disabled?

    I’m actually in Auckland. Do you come north much?

    Hi Chris,

    Yes the AK4218 is still a current model, I installed one on a Toyota Hilux this morning.

    It does not work with Toyota’s that have proximity locking, however the AK4615 is another option if you have a proximity key. (I’m assuming you have an O/E system).

    I’ve already done my Auckland tour for this year. Will probably do another one in 2016, but will have to book in enough work up that way to make the time and travel worth my while.

    If you can’t wait that long then you are more then welcome to head down to Wellington.

    Cheers

    hey Julian
    Just wondering if the ak4218 would be available in Australia, because i contacted cobra in Aus and they dont recognise that number.
    Also just after more info on how the alarm uses the factory remotes as you say “the AK4218 reads the Toyota remote signal” does it just hook up to the vans reciever module? or it uses the remotes frequency

  8. Julian Julian says:

    Cobra alarms are not sold in Australia.
    The cobra-aus.com.au is not an official Cobra dealer and it is a fraudulent website so be warned!

    The alarm is hard wired to the receiver module.

    Please note that I do not offer sales or support outside of New Zealand.

  9. Hello Julian

    What is the difference between the A4615 and the AK4218?

    We only have the A4615 in the UK!

    Good blog by the way..

    Hello Car Alarms Essex,

    I’m trying not to sound sarcastic but “read the blog post you just commented on as it explains how it works” 😛

    Hi Julian I have a 99 toyota supra with a mongoose m60g alarm fitted about 8 yrs ago now lookin to upgrade to something up to date that has smart fone capabilities meaning the fone can also be used to arm disarm plus other functions what is out there for my car and by the way I have had no probs with my alarm only flat battery on remote twice however the last time I replaced the battery I still had a problem disarming it so I got help from AA which was a easy fix however I had it tuned up by a very reputable garage in Dunedin on picking up the car the mechanic told me had no horn but on arrival home I also could not use the remote took it back to them and another mechanic looked at it what i think happened was the firts mechanic pulled the bullets out to disarm it and plugged wires back wrong which caused it to blow 2 fuses horn and flasher which disabled the alarm including engine immoblelisor hence I was back to using the key entry which brings to mind if you pop the correct fuses will that disarm all alarms if so would this defeat the whole purpose of an alarm

    Hi Harry,

    I see that you are in Dunedin so I’m not able to make any recommendations.
    This post explains why: http://vehiclesecurity.co.nz/blog/why-i-cant-make-recommendations-if-you-live-outside-wellington

    If you are coming to Wellington at any stage then let me know.

    Cheers,
    Julian
