Six year old car, 115k on the clock. Starting last week, I've been unable to unlock the doors on the es. Whether it's via the key fob or the sensors on the door handles. I've noticed the behaviour in the morning when it's cold, so I'm assuming it's mechanical. When the weather warms up, everything seems to work again. I've done some research here and while nothing turned up for our es's, I think it might be the actuators for the locks based on responses I've seen from the is and gs owners.

I guess the weird part for me is that all locks but the driver door lock seem to have failed - all at the same time. I can lock, but not unlock. Trying to figure if there's singe common point of failure which would cause three failures simultaneously. Perhaps it's just coincidence?

Anyway, I'm fully prepared to remove the panels and tackle this project, but wanted to see if anyone else ran into this? Any advice? Any idea what might be the culprit?

Thanks in advance.

Before you start taking the car apart, have you tried replacing the battery in the fob?
