Few bad alarms, many bad key switches.

If you don't care for the alarm, pull the front passenger carpet, remove the false firewall, pull the connectors from the Becker box on the left side of the footwell.

If you want the alarm, unlock the door, open the door then turn the key back to lock. The door won't lock because it's open and if you do it quickly enough, you'll catch it before the alarm sounds.

I understand the switches are not available separately. You have to get a new door handle or something like that.
