driver door locks broken - key spins helplessly

When I put the key in my driver-side door and turn it nothing happens, no lock, no unlock

I believe it is mechanically broken due to forceful unlocking. I didn't feel it happen ever, one day just went limp.

I'm pretty sure my problem is not that "door lock relays in the GM5 module are shot."


How can I fix this - locksmiths won't touch it, they say go to the dealer
I did he said around $100 just to pull the panel off and find out the problem

According to the Bentley manual, the lock cylinder has a fragile plastic tab that is designed to break, to thwart forced entry by, say, a screwdriver. After it breaks, you put your key in and it just spins around and around.

Fortunately, the part is relatively inexpensive from the dealer, which (I think) includes keying to match your VIN. May take a day or two to get it though.

Part #11, $60-80ish, I assume the price difference is whether they match your car or not.


Sorry, I don't have any details on the actual installation procedure.

Number 11 is what you need. No need to remove the door panel there is a 4 MM Allen to remove near the side of the door then it pulls out.

They are ordered via vin and keyed to the car. You need a Drivers license and title to order from the dealer.

Pretty simple project should be done in less than 1 hour for your first time

Hi all,

I had this same issue,
fortunately i was able to do a DIY on this by buying part 11 from a salvage yard.
Unfortunately it was quite a b#$@# to figure out since the internals of the part are very slightly different between a facelift and pre facelift model.
Took quite a while and sore fingers to get it right. If its a relatively in-expensive part, i'd say get it done at the dealer - but it is a possible DIY.
Also i didnt know it could be removed without removing the door panel, only realised it after removing the whole damn thing and figured it out it couldnt be done that way, this added to my frustration of this DIY .....

THANK YOU. im going to do this DIY this month lol.

I broke my key in the key hole in the winter and it was turning and turning and turning, the locks smith said WOO go to the dealer. i then broke off the key in the door. then i had to go buy a new 200$ key with remote. and now the only way to get in my car is by remote. so i rather fix this issue before i sell it.

grazzz

I've had my car for over 8 1/2 years and have never (not even once) used the key to lock or unlock it.

For the hell of it, I'll do this when I get to the car this evening.

Good luck with your repair

Easiest dyi ever. Buttons on my key do not work so I always use door. I suppose one day I'll stop being cheap and replace with a working one.

Part was less than 100 bucks from dealer and dyi took all of about 3 minutes...maybe less.

Cannot get this part from a salvage yard as its specific to your key...If I recall correctly I needed my registration and ID when ordering this....DO NOT HAVE THEM DO IT. A monkey could do it blindfolded.

Mine broke, but didn't spin all the way around. The key would stop at the 180 degree positions, just like normal, but there was no resistance when turning the key and it did not lock or unlock the door. In my case, the locking cylinder was broken. You can order the aprt by VIN at the dealer for approx $100. Installation is really, really easy. Open the door, loosen one screw, pull out, replace the colored cover, and reinstall. 30 mins, tops.

I have this problem too. I took off the door lock and noticed the small little "plastic" tab that makes the rod turn is broken, and fell right out. Can i replace this little piece or do I need to replace the entire locking cylinder assembly?
