Cobra AK4198

Please note: The Cobra AK4198 has now been replaced by the Cobra AK4698

The AK4198 is part of the new generation of alarms available from Cobra, whilst there was nothing wrong with the old models the AK4198 raises the bar in almost every area.

Gone are the odd-looking remote controls found on the AK3198 and AB7928. In its place is a tidy two-button remote which has a separate lock and unlock button. Cobra has also addressed the issue of your car being stolen with the keys with its optional Drivers card, which is simply brilliant. Every time you start the car the alarm looks for the card. If it does not see it within 30 seconds the remote gets blocked the anti-hijack system kicks into life.

Cobra’s Ultrasonics – Very tidy

Ultrasonic Sensors look factory. Both sensors can be painted for a perfect colour match.

Cobra’s Ultrasonic sensors come with factory looking pods that really look the part, they replace the “old style” ultrasonics which used to tuck into the top of the “A” Pillar which never really looked all that flash.

The Siren has always been a strong feature for Cobra and still is with the AK4198, it is rugged compact and most importantly bloody loud as well as being small enough to hide on the majority vehicles.

Easy Over-Ride System

The LED is housed with the pin code over-ride button is still the same as the old alarm, but then that was always a good system and far less annoying than most other alarms which involve having to cycle the ignition key on and off and waiting for the LED to flash! The only downside is that the LED is only 3mm in size and is arguably not a great visual deterrent. Having said that there is nothing from stopping a good installer from adding a second larger LED to the system.

The only thing which I do not like about the AK4198 is the fact that it doesn’t offer boot pop as a feature, a big oversight by Cobra in my opinion. Apart from this small point, I have nothing but praise and in Cobra’s defense, they do offer other alarms with boot pop for those who require it.

Stylish Simple and Rugged Remote

Two Button Padlock Remote – Part # 4T8722B7 – Battery #CR2032


The remote comes with two buttons which do exactly what they should.

The Lock button Arms the Alarm and will close the windows if held down (where total closure has been installed). A second press within 22 Seconds turns off the Ultrasonics and a third press will turn off any additional sensors such as the optional Level sensor.

Car finder is activated if the Lock button is pressed when fully armed (after 22 seconds) and will beep the siren, a second press will then activate the panic mode.

As for the Unlock button… Mmmm, well you’ve probably figured that one out, if not then it is a minor miracle that you’re actually reading this!



RRP: $650.00

Obsessive Rating:
So good that it’s in a league of its own

Looking at most of the competition it would be easy to think that Cobra was 20 years ahead in terms of technology and that’s being kind!

    Hi There,
    Fantastic website by the way!
    your good reviews on cobra alarms were the deciding choice for me getting a AK4198 installed over a year ago. I’ve been very happy with the alarm. No bullcrap, it just works! (and doesnt piss off the neighbours!)
    I just wondered if you might have an answer to my question.
    I just recently completed a whole lot of engine modifications, including a new turbo which is running pretty high boost.
    So i thought a turbo timer would be a good idea to help the turbo cool down properly. Its all installed, but the alarm wont let me lock it till the car has turned off.
    I realise that its hard to immobilise a car thats still running, but is there any way around this without compromising the alarm?

    Hi AJ,

    Thanks for the feedback, great to know your a fan of the AK4198.
    I have a solution which I’ve been meaning to do a blog post on for over a year now so I’ve finally pulled my finger out!

    Flick me an email if you want to go into the details about your car rather then make it public and I can give you some customised pricing option.

    Hi Julian

    Im looking for a decent car alarm after having my car keyed, so have been doing some googling and stumbled across your website after making making a list of various options.

    I see you rave about Cobra but I can’t seem to find a place in Auckland that installs these. Do you have any ideas? My budget is around the $500 mark give or take and I have keyless entry on my vehicle.

    Also if you can recommend any other options im all ears. Thanks.

    Hi Melanie,

    Sorry to hear you live in Auckland.

    This post explains why I can’t make any recommendations if you live outside of Wellington.

    Hi Julian, you put in a Cobra alarm for me a couple of years ago and it’s been great however it’s now going off all the time for no reason and it’s got to the point where I can’t use it which means my car is unlocked and unalarmed all the time (and obviously won’t be covered by my insurance). What can I do? Many thanks, Lorenda
