Car Alarms: car alarm, front doors, car alarm

Question
I replaced window regulator in drivers side. Now when I go to open car with key on that door the alarm goes off. I have to open the front passenger door with the key to shut off?

Answer
In most cars, that's the way a factory alarm
is disarmed. But it's both the front doors, so have
a look at the work done on the drivers door as
the wire to disarm it seems to be missing or broken.

take the panel off the passenger door to
see which one if not evident when looking at the
door you did the repair on.

Good luck.
