Hello all, as the title says, my keyhole lock does nothing when I insert the key and turn it. There's a whirring sound but the actual lock knob doesn't move one bit. Sometimes there's even no whirring sound.

 

Eric, you likely need to use WD40 in the lock cylinder and maybe the rest of the door lock assembly. Use a lot of it followed by the key back and forth to exercise it. If the key looks very worn out, maybe you have another key to try?

 

Will try this, and no the key is in good condition. I have an unused spare which I have tried as well too, and it does not work. The keys do in fact turn in the hole, it's just the fact that when it does turn, the lock does absolutely nothing.

 

I don't think it's turning far enough. The key slot never gets used so do as Addicted2boost suggested. Maybe a lock lubricate instead of WD-40?
I bet with some further working of the key it should free up and unlock the door.

I think you need a lock lubricant (which WD40 is not). Spray it in the lock and give it some time and then spray it on the key and work it back and forth in the lock firmly but not excessively. Rinse, lather and repeat (not literally) as needed ten minutes later. The trunk lock in my Series 3 was similarly seized after too long in storage which was particularly frustrating as I needed to access the trunk to reconnect the battery…

 

I hear ya Ken, it’s just a means of getting some movement outta the key and figured just about everyone has the WD40 within reach. Chances are it’s the lock that’s frozen up inside the door and not necessarily the key cylinder. I use a different kind of lube at work made by Wurth for lock assemblies.

 

I know what you mean about everyone having WD40 within reach as that includes me.

In most cases it will provide a temporary fix and I wouldn’t have said anything but its biggest drawback is that it first attracts dirt and second it evaporates relatively quickly compared to something like the Wurth products. As dirt is probably the problem in the first place with a lock, even if you unseize it, the short term fix will exacerbate the problem in short order

You’re right! But doesn’t everyone want the ‘here and now’ results? 😄

 

Use a silicone dry lubricant spray, you can get at any hardware store...as said by Ken WD40 is not a lubricant even though it states it is.

Take the door panel card off and see if you may have a broken clip as well. The key cylinder is totally mechanical, but operates the electrical aspect through a rod.
When you get the cylinder to turn, turn and hold the key to the left...your parking lights will flash once, the doors will lock, and if the windows are down they will roll up. Release key.
Hold key to the right, parking lights will flash once, doors will unlock, windows will roll down.

I'd take the door card off and check the clips and connections. The cylinder (and exterior handle) are removable from the inside the door, ....when reinstalling put a drop of Loctite on the cylinder screw. Be careful (have a pickup mag just in case), if you have big fingers, it'll be a very tight space. Check your weather gasket while there. I've replaced mine, quite simple, but taking the door cards off is the PITA. Use a grommet tool.

...had to do some digging to find these. This new setup has my old posts a pain to find.

 

Do a search on the door card if you have to take it off. A grommet tool will help not breaking the plastic; but the key is a piece has to slide forward . . . to allow its separation from the door.
