Honda CRV 2002 Power Door lock

there is an electric motor attached to door latch. you need to remove the door panel and take out the latch and then replace this electric motor, called the door lock actuator.

Look in the owners manual to see if you have a child lock out switch or button. I have seen it where the child lock out prevented the locks and windows from operating, except on the driver side.

Start by having your car checked for a Trouble Code. Many Auto Parts stores do it for free. It seems to be a security issue that keeps locking the door. It is a system which works separate from all the other systems in your car.

In my Honda, with the door ooen I can pull the inside handle, hold it, and hit the lock switch and it will lock all doors including the drivers door.

You can get the door panel off without the door being open, it is very difficult but doable. The other choice is to have a locksmith come out and open the door manually with a slim jim.

Electronic Chassis Control Module remote door lock module located in the drivers door. Black about the size of a pack of cigarettes.

I think you will have to start looking at the wires that go into the door by the hinge it could be a simple broken wire but you might have to remove the door panel to gain access to the locking solonoid by the door lock and check for power to it when operated, or the link that connects it having fallen off. (if fitted with a link, but normally are). No power to the solonoid is probably a broken wire or dirty connection, power but no movement is probably a stuck (seized up) or burnt out link/lock/solonoid.

-If the problem is that keyless remote does unlock or lock door, but the lock lever still move when pulling up and down by hand. Door still open and close with both inner and outer, then might the driver door lock actuator is bad. The actuator lock and unlock the door for you when using the keyless remote or door lock/unlock switch.

-if you try using the key to unlock door and the key doesn't turn the door cylinder, then you have a bad door lock cylinder.

-if the lock lever doesn't move up or down and you can't open door using any handle, then you got a bad lock latch assembly.

I'm not sure what the issue is but hope this helps you.

the little motor that operates it inside the door is probably frozen, so it will need to be replaced!!

its most likely broken you can get one at a scrap yard
