I have an 05 TL and I just started having some problems with my door lock. I have set my keyless preferences to enable the door lock confirmation beep. Not only does it not beep (door locks fine, just no beep when I press the button again), when I've set the preference to have the door auto lock after it passes 10 mph, it would relock everytime I go past 10 mph even when the door is already locked (like after stopping at a stop sign or a red light). I have also noticed that the security light at the door no longer blinks.

Has anyone else have issues with the door lock like this?? If you do, I'd appreciate a little pointer to see if I can find a quick fix so I don't have to bring it in. Thanks!!
