Just got my dream car, a 2004 TL 6 speed with those big brembos..... but for some reason I can't lock my car with the key fob or the switch? Only way to lock and unlock is with my key? It's the driver and passenger doors only affected the rear door seem to work just fine. Oh yeah seems when I'm driving I can hear the locks engaging at random times...

 

Check the actuator... Or it could be the power supply to the power lock mechanism...

You'll have to pull the door panels... Have fun!!!


Sounds like a nice car, BTW!!!

 

door lock actuator is bad. Replace them.
