I have a 2007 Toyota Corolla. It has power locks and a keychain remote.
The keychain remote locks and unlocks the car. The key unlocks the trunk. However, the key does not unlock either door lock. As far as I can tell it is going into the lock ok, but does not turn.
Other things of note. I live in Minnesota and it has been well below freezing recently. The car battery is old. I don’t think the key is a valet key, but I can’t rule it out completely. I know the key worked in the door locks in the past and starts the car with no problems once I get in.
I suppose it is possible both door locks are frozen, but the fact that it happened to both at the same time makes me skeptical. The fact that the key opens the trunk makes me think the key is OK. The fact that the remote unlocks the doors makes me think the battery/electrical/power locks system is OK.
Any ideas what is wrong in the long term?
Any ideas how to get into my car in the short term? I knew this was a problem, but still managed to let my wife leave this morning with our only keychain remote.
