The alarm sounds when I try to LOCK the car with the master key. Unlocking immediately stops the alarm. This works same for any lockable door (driver/passenger) and the trunk.

The radio was removed recently (3 days ago) under normal circumstances (with an open car) and the wires are currently hanging in the radio compartment.

I can start the car and everything else seems to be in order.

I disconnected the battery for 30 sec, but that did not help...

My current solution was to let the alarm run for 60+30+60 sec, as I need to loack the car...

Any suggestions? Any way to re-set the alarm?
