I have a similar problem with my 04 coupe. Drivers door will not lock with the fob, but mechanism works ok with the key.
Locking with fob, passenger locks, trunk locks, gas filler door locks.
Now when you open the drivers door, the siren goes off. So I have to unlock with fob before opening drivers door. The car thinks Im breaking into it.
Diagnosing. Pump cavity all dry, no evidence of water ever. Pump seems to run much longer (30 sec) after each lock/unlock event. So I thought maybe a leak at the drivers door.
Investigating. Air lines run from pump direct to gas filler door, and with a tee from another line to the trunk
Lines remaining go to passenger side, presumably to the passenger door, and then onward towards the cowl and a left turn under the dash to the drivers side.
Line at drivers side is visible with an inline connector if you remove the kick panel. Helluva time splitting that connector. Sucked on line to door, holds vacuum.
So I'm at an impasse. Will make do locking with key until I get another brainstorm. Any ideas welcome
