Hi

I have a mk3 Seat and the car alarm keeps false triggering, sounding

is there a way to disable the car alarm?

You have three possible options: Ask your friendly Seat dealer, who will probably say it is not permitted to disable it as it is type approved for Thatcham Insurance rating.

Option two is to ask a well established auto electrician to disable it.

If all else fails ask around in the local dodgy estate for an experienced teenage car twocker.

Don't know about your Seat but on Skoda older models have a button either on the drivers door card or on the B pillar that you can press and then lock within 30 seconds. That disables the internal monitoring and the alarm. Later more recent models, you just double lock the keyfob. The alarm is disabled on the second click of the fob.

Spurious alarm issues on older cars (Skoda) are usually related to an expired corroded nicad battery contained in the alarm unit, which on a Skoda fabia is hidden somewhere near or under the offside front wheel arch. Either replace/disconnect the unit or it is possible to repair for someone with the right skills

I would think Seat would be very similar.
