Door doesn’t unlock with key fob

[jakebvrs]

As you can read from the title my V70 01 seems to not want to lock or unlock with the key fob which causes me to enter the key. Now it’s not the end of the world i know but it’s just that sometimes the lock is sometimes frozen causing me to unlock it from the back door. I’ve tried to “reprogram” it by doing some tricks and it seems to be making noises now which makes me think it still has some life to it.

Any help or advice would be appreciated. thank you all !

Mm...money, will cost you if...?

Your video reminded me of the beginning of PF's video. Could be the same assembly as my 03 S80 T6. Remove door panel and see if it works, perhaps something is binding. Remove the actuator assembly, take apart, greased the gears and most difficult of all shimmed the little DC motor. Take that back the assembly just fell apart so took me several hours to figure out how all the gears go back together. Will cost you $ome money if you can't repair the actuator motor unless you can match one on eBay for cheap.

I just changed the driver door actuator on my kids 2007 Ford Focus before Christmas, not a terrible, just fiddley fishing it out on that car.

On his the fob would unlock all doors except the driver one, like you, had to use the key on the driver door.

From the video it sounds like the other doors are unlocking and the one door isn't, which in my experience is the problem is with the door latch/lock assembly for the door that's no locking or unlocking. The problem (I think) is usually due to do one of two micro switches although it can be other problems within the sealed assembly, such as a little motor or linkages. I had a metal linkage arm break in one my car's lock. For the two sliding switches; one switch is for the door open/close position and the other switch is for door lock/unlock status. You can't really get to the switches to clean or replace them so a whole new lock assembly replacement is required. For my 2001 I've replaced these lock assemblies in 3 of 4 doors over the years. I've had pretty good luck with the lock assemblies from the salvage yard.

My handbook for MY01 XC says "do not use the remote inside the car". I have some experience with central locking on the xc, having several remotes present can confuse the car, so can recently triggered alarm codes. I suppose the most obvious question is do you have any other remote programmed to the car (Volvo allows up to 4) and have you tried them?
The other very obvious point to check is are you sure all other doors and boot/trunk are fully shut? If not then what you are seeing is normal. Do you have Vida/DiCE if not contact someone who has and stop guessing; get the pointer from the diagnostic code as where to look. Don't bother with a generic code reader. Good luck.

PS There is a microswit in that unit I think. On the XC70 the tailgate unit comes in two versions 5 seater and 7 seater. On the latter apart from being able to open with a key from outside (hidden under illumination for index plate) there is a more robust design and an internal handle to open from inside. When I swaped out mine 2 years ago I found a poor harness conection in the rearmost piller high up near the roofline. Do you have childlocks (not just the mechanical button but electronic control from drivers door module?) and what about deadlocks. I have both and automatic locking after about one minute. These combinations can make diagnosis very complicated. Vida actually warns that deadlocks in Swedish versions for the police can throw false positives for sinal too high, signal too low, I have been ignoring then for 15 years now.
