I noticed that my door locks have about few seconds delay to lock the doors after pushing the lock button. It used to be instant.
unless they finally changed it for Gen4, no warning really. bisco has it right, pull your hood release and then check it in the morning, dont open drivers door or anything before checking. edit: i will say it was about 3 years to the day that I first had to replace my fob"s batts
If the door sensor opening and closing is working fine - I'd suspect the 12v is fine too. Particularly as everything else is working fine too. I'd be checking or changing the FOB Battery first.
Could it be one or more locks are stiff ? Maybe a little thin (3 in 1) oil in the keyholes and work it with the key a few times, it's worth a try.
Possibly - except that it works fine with everything except the FOB - which I think points to the FOB.
I guess it was my assumption that seeing he said FOB that everything else is OK - I'd asked him. But - cars and particularly computers and electronics can be sneaky!!!
