Haven't been on the forum for ages, but hope that there's still someone here with some useful advice.

I've recently moved house, and with all the boxes & unpacking etc I've "misplaced" my Blue Coupe key & alarm fob.

Good News - I still have my Red key, and can open the doors and start it.

Bad News - The alarm is still active (although I'd turned the siren off a while back). Hence the indicators flash etc for a while whilst in it.

Is there an easy way of just disconnecting the alarm system, or otherwise deactiviating it without the keyfob. The alarm fob is/was rectangular with two square buttons at the top (one raised, one indented)?

20VT 1998 R reg.

Hopefully keys will turn up again eventually, but any assistance is appreciated.

It's a Scorpion alarm, you have PM

I had the same issue (although my fob stopped working not that I lost it lol)

All you need to do is get hold of another scorpian alarm box with fob (or 2 is better) and replace the alarm ECU box.

Its located behind/above the fuse box under the steering wheel.
An arse to get to but only a couple of connections.

Once changed, all sorted.
