VOLVO 2000 S80 BOTH REAR DOOR LOCKS DON'T WORK WHEN I TRY TO USE THE KEY FROM THE OUTSIDE OR THE BUTTON ON THE DRIVER'S DOOR.

check central locking system fuse it controls all door locks and other acessories.need go to dealership buy remote keys..

If you can get in the rear doors (?) the driver side comes down and you will have access albeit a small space to find keys, use a flashlight and if you have a 10 yr old around they can slip in and back out of the trunk although this is a last ditch effort. get a tool with magnet on the end and sweep the trunk until you locate the keys

can be the rod going to key lock keyless entry work on a different one

check the child safety lock
if that doesnt work it may have come disconnected or possibly broken on the outer door handle-inside the door

I had a similar problem w recently bought 2003 S80.Several points: 1) Access your locking selonoid through the trunk interior panel ... loosen a few hex bolts and slide out for maintenance; 2) I fixed my lock by simply using light teflon-based oil (like for bike chains). I exercised it a few times and it works beautifully; 3) Not sure on your model, but gas door on the '03 unlocks when you push the associated release button under the headlight control switch. It is not designed to unlock w the key (again, check owners manual for your year). Hope this helps. master_pre08-04-2007, 09:35 AMYeah, the fuel door on my 2000 S80 is connected with the door locks. In order for it to open you have to unlock all the doors to the car. Sssnake08-14-2007, 03:39 PM Thanks Guys,

I removed the locking mechanism and applied a little silicon graphite and now it works like a charm.

did you try key in the door, lock, unlock and lock?

hav car scanned for free at a discount place-the avg car today has ten computers!

Try resetting the electrical system by locking and unlocking the doors with your key in the driver's door 5 times in a row. A service manager at a Volvo dealer showed me this after they did some work on my car and on the way home the sunroof wouldn't close.

I have a 2001 S80 that I have to reset the electrical system like this every time I disconnect the battery. All kinds of stuff stops working...sun roof, door locks, lights, radio, windows, etc. Just reset like described and everything should start working again.

Good luck.

you have bad door lock motor

drivers door module is bad
