L322 Alarm going off1 minute after locking

[CBH25]

This is getting annoying.
My alarm goes off most of the time I lock the car after 30 seconds to 3 minutes.
Flashing indicators and horn sounding.

Anyone know what the likely cause is?

Also Id like to be able to turn off the internal motion sensor, but if I press the remote lock button after locking the door, nothing seems to happen. Any help please.

Check/clean bonnet alarm switch, also if you hit the key button "twice within 10 sec" of locking it should disable it.

Hi CBH25, as Laurie posted, check your bonnet switch, I had trouble with mine triggering intermittently and found the bonnet switch was slightly out of alignment.

What you can try to see if it is the switch. Get a thin piece of styrofoam and place it over the bonnet switch, close the bonnet and and lock up and see if you still have a problem.

I permanently fixed mine by sticking a small self adhesive rubber pad on the underside of the bonnet, where the switch contacts the bonnet.

Thanks gents brilliant.
It seems to have worked.

Hopefully it will out others inthe future when they search.
