Car Alarm/Immobiliser Removal

Car Alarm and Immobiliser removal is one of my specialties. Whilst I would rather install quality systems, there are a huge number of crap unreliable car alarms out there, many of which I have reviewed and suggest should be avoided at all costs. If you have one of these then it is only a matter of time before it will fail and you’ll need it removed or replaced.

How many bad car alarm installers are out there?

From what I’ve seen there are not many competent installers around. It seems to be an “out of sight out of mind” mentality with most, working on the assumption that you’ll never see their shoddy wiring attempt hidden behind the dash. More often then not the cars wiring loom gets butchered!

Part of my job is often patching up the mess at a later date. Below is a typical messy install which needs putting right:

Awful Vehicle Security

The most common brands I remove are AVS, Mongoose, and Meridian. They are a magnet for incompetent installers so be warned! If you want to know who to avoid I’d suggest the AVS and Mongoose list of “approved installers” would be a good place to start!

AVS = Awful Vehicle Security

9 times out of 10 I find the alarm module is poorly placed behind the driver’s side dash held in place with little more than a Zip Tie. These are often a hazard as they could potentially fall down on the pedals or get suck in the steering column!

How Much does it cost to remove an alarm/Immobiliser?

Typically between $120.00 to $160.00 including my call out fee. It really depends on where you are and how long it takes to clean the mess up!

If I’m replacing it with a new system then it is normally free of charge.

    Hey there,

    Need a mongoose imbolizer removed from VW transporter.

    ASAP if possible


    Thank you

    Hi Turi,

    Whoever installed the Mongoose should be shot! The 2009 Transporter already has a factory immobiliser so they’ve simply fitted an unreliable time bomb that is going to fail.

    I’ve responded to your email too and edited your phone number.

    Good luck

    I HAVE got AVS A4 car alarm installed on MAZDA Demio 2004. it does not give 4 second chirp or flash light warning if door is left open by mistake while arming Alarm.
    after programming it gives 4 chirp either door/boot is open or closed. thecar has 30 second dome light delay before it turn off.
    i want to know
    1—-is it fault of installer ?
    2—if you are able fix it then how much would it cost?

    Hi KHOKHR,

    Sorry to hear to have an AVS. Interesting that you commented in the “Car Alarm/Immobiliser Removal”
    as that is what I would be doing if I found one in my car.

    It sounds like the door input wire has been connected to the dome lamp rather than directly to the doors.

    Question Reply:
    1: Probably, but you should contact them first to put it right if you need that feature.
    2: Yes, but see above 1st. I would need more details before being able to quote such as your location and year of the Demio etc.
    I’d probably have to charge on an hourly rate as it’s always interesting correcting other installers work.
