Dooor lock repair - 1999 Ford Explorer

don't see a model/make but the clip(s)broke or were knocked off 1 or more of the locking rods-usually by a slim jim,but you have to get a pro to open dooor to get panel off & then find what rod(s)are disconnected

Also check your battery for low voltage.

Either switch is bad or wiring going from the door to the body.

There may be an obstruction in the door that should be looked at by a lock smith. It also could have been tried to picked by someone. Also try putting the key in different ways.

The apparent problem, is the electronic detector, on the solenoid that operates this individual lock.
You will have to remove the dooor trim panel to access this.
the cause may be the connection is contaminated, by weathering.
Chafed by contacting another door panel part.
Or failure of the energiser solenoid.

Hi, I have a Toyota Camry sportive '05 and I have a problems in central locking system . Since two days I can't locked my car with remote key . I can open by using a key ... Can pls give some ideA about the problems .

unlock relay is bad... ???.. amazing

pull off the door panel, feel inside the door by the lock and pull the rod that it connected to yourlock unlock switch on your dooor

There is a relay which locks the doors after you begin to drive. When this guy goes bad it squeals like a pig! This happened on my 2000 Concorde and we had it replaced at the shop for about $100.
