I have seen 2 FD's with broken door locks due to aftermarket alarm that utilize a door mechanism to lock/unlock doors.
The clips on the FD door lock hanger are plastic, sooner or later due to the impact of the alarm mechanism they will break off, and u won't be able to open ur door.
I know cuz I am one of them.
I had to jimmied the door open, and find spare parts off another FD parts car and fixed it.
Ever since, I decided screw the alarms on the FD. Get full coverage.
