    I am having the exact same problem. I would hate to have to take it to the dealer.

    When you drive over 5 mph the doors automatically lock. They jump up and down and unlock. It does the same thing when you lock the car with the remote?

I had this problem on My 1980 280SE and now on my 2003 E320. You probably have a loose connector in the drivers door. You have to remove the door panel and tighten the wire connector (it may be hard to reach). After I fixed my 280 the problem never reoccured. I am taking my 320 to a local shop. I'm getting too old to remove door panels. I do not know why Mercedes doesn't fix this problem on their cars.

Good luck all.

A plastic clip that holds the lock linkage is probably broke or worn. You need to pull of the inner door panel to see whats going on inside. Use the remote and see whats happening. It could be bent rod in door from someone using a slim jim to unlock it when they locked the keys in it at some point. Bend the rod and try the remote again untill it works properly.

General advise:The lock is not ok.The same wires that lock the doors,unlock it.Before removing the lock:ceck fuses,door wiring link (near the door hinges)U may have to figure out the link covered in removabile rubber(it has a lock pin and must pull down in some cars rotate)U can clean it by air gun and contact cleaner.Rare:The door unlock pin (small plastic knob that u unlock manually from inside)has the rod dirty/stucked/twisted,ceck it to move loose.Also spray chain lube and wd40 anywhere in the lock u gain acces (the key hole,from sides,from the pin lock).U can see if it is stucked if the unlock knob has the intention to rise (small moves) but does not pop.Cheers.

Battery is DEAD on 2003 Ford Escape! Door key (using an actual key) unlock is also motorized, which needs battery juice. I can't get into this car! I thought about putting jumper cables on the sta

Open the door manually with the key!

Many Ford Escapes have power door locks as standard equipment. This system consists of a lock switch, lock actuator and wiring harness. When you depress the lock switch, it sends an electronic signal through the harness to the actuator. The actuator moves an internal piston that either pulls the actuator hook down or pushes it up. The actuator hook connects to the lock rod, which either locks or unlocks the door, depending on which way you push the lock button. While this system won't work with a dead battery, the mechanical lock system remains unaffected by electrical power loss.

Insert the door lock key into the driver's door lock.
Turn the key counterclockwise one quarter turn.
Pull the door handle up until the Escape's door opens. Once the driver door is open, simply open the remaining doors by pulling the interior door handles until the doors open.

Driver's side lock on isuzu rodeo broke and can't get the door open or unlocked. how do i go about fixing this?

where the knob is poking out the door trim ,get a conventional oil can and allow the oil to dribble over the knob and slowly run down the knob ,as eventually it may just lubricate the electric door lock solonoid if your lucky after a day or so

Sounds to me like perhaps there's an electrical issue going on here. You will probably need to take it to a mechanic or dealer to get fixed. I mean, if both the remote and the buttons fail to lock/unlock, it really sounds like an electrical issue.
Do any of the buttons work on any of the doors? If so, it may just be the driver's door that has a problem.

Radio, Key auto door lock/opener, interior lights not working.

Most likely is a fuse. There is a fuse box at the end of the right side of the dash. Open front passenger door and there is a cover that says fuses on the end of dash. There is also a fuse box located under the hood at the right front of engine compartment. It should have a cover with a round knob in the middle of it .Unscrew the knob to remove cover.

you need to spend some time triing the best you can to get the top of the door panel open a bit to see what is broken inside, most likely a clip.The other thing to try is a slim jim to get the door open then repair the door lock.

2004 Civic Drivers door lock

The driver's side door lock button is designed not to lock from the inside unless the handle is pulled, or the power switch is used. This serves as a reminder to not lock your keys inside.

If you are inside, and push down on the button (not the switch) hard enough to lock it, you've probably damaged it.
