Wife just called with a weird one. She said the doors won't lock - using either the key fob or using the door lock/unlock button on the car interior. They will lock, and then immediately unlock. Won't stay locked. Since the car isn't here, I'm shooting in the dark, but I'm having her check: Make sure all doors are properly closed/latched. Push a button on the key fob to see if the LED lights up (I changed batteries a year ago). Couple of searches showed up: Potential issue with lights on when car is turned off (never had this issue before). Someone mentioned a switch below the dash to right of steering column. Any other ideas?
stuck button on the keyfob? check to make sure the unlock button isn't stuck. Is there a second key fob that might be inside the car? The car won't lock if there is a key inside.
I've got the second fob with me. Might be a stuck key. Not sure since wife has it, and she is technically and mechanically "disinclined". I'll have to wait until she gets back tonite to look.
you can tell it's stuck if you can't press it down. It's stuck in the down position. This is actually a common thing for these fobs, I've read many people with this problem and I've experienced it myself.
Not if using the fob outside of the car - Although the OP did say it wouldn't lock from the inside either (assuming the fob was inside the car.) This is how it works on the Gen III - not sure about the Gen II.
