I can put the key in the lock on the driver’s side, but it won’t turn to unlock the lock. The lock on the passenger side works fine. I’m tired of unlocking it there and then walking back around the car to get in. For what it’s worth, we’ve had some terrible winter weather recently. Is there a quick and easy way to fix this?
Best answer: Frozen. Squirt some lock de-icer (or WD-40) into the keyhole.
Alternately, find a warm place to park it for a couple of hours.

Best answer: Yup. Frozen. Definitely get a de-icer spray. Alternately, heating-up the tip of the key with a lighter before you stick it in has, on occasion, worked. Not sure if that’s recommended for today’s micro-chipped and sensored electronic keys, though.

In case it turns out not to be frozen, they can sometimes get jammed. My last car had a jammed lock on one side (so I didn’t lock it). I wasn’t able to resolve it and the locksmith wanted to charge too much. WD-40 might work even if it’s jammed though.

Also, a blowdryer if you have a long enough extension cord.

If it’s not frozen, pop open the keyhole cover with something small and pointy and take a peek. Last time this happened to me it turned out that the keyhole cover had broken off and a small piece of it was jammed in the lock. I was able to pull it out with tweezers.

We had a stuck door lock. Went to a small locally owned locksmith and they sprayed something, think it was a graphite spray. It definitely was not a de-icer. (It was summer in South Carolina.)
It was incredible how quickly it made it work like new.

Rub the business end of the key with a soft pencil, then insert.

Response by poster: I have some graphite spray here. Assuming the lock is frozen, will it help? Could it make things worse?

Graphite spray shouldn’t hurt but I’d try WD-40 first. If you can hold back the sprung cover with a small flat screwdriver, get the nozzle of the spray right in. This will clear out any debris that may be lodged in the keyway. The more likely explanation for your problem is that the wafers/pins are bound together. This technique will kill two birds with one squirt.

Graphite won’t help for frozen things, but it won’t hurt either. You don’t have WD-40? Good lord, get thee a can immediately. 1000 uses.
Does the door work from the inside? Have you tried working the inside lock/unlock? Bring the window up and down?

NO — Do not try WD40 first — WD40 is a recipe to get nasty gunk and crap stuck in your lock. Graphite and only graphite first. If that doesn’t work, I would venture to guess that the wafers in your door lock have worn down to the extent that you need the lock replaced. I worked as a locksmith for many years and saw many people who would come in with this exact problem. Either their key was incredibly worn down (almost smooth) or the inside wafers on their door lock were worn down thus giving the impression that the lock is seized up. I would have to re key their door lock an cut them a new key that would also turn their ignition switch.

I had this exact thing happen to me this over the past few months. It worked better in warmer weather but still stuck sometimes. I tried it all and nothing worked. Finally just had the dealership look at it whilst getting an oil change and they fixed it right up for free. They said it just needed some lubrication but they didnt specify what it was. I that an option for you?

Go to Autozone and buy a can of CRC brand Freeze-Off Spray. It makes WD-40 look like water.
Take a good look at your key and make sure it’s not bent or developing a hairline fracture, too.

Response by poster: I never got around to doing anything about it, and after a few days of warmish weather, the problem went away by itself. Looks like the lock was just frozen after all. How anticlimactic. Thanks for all your help.

Response by poster: As an update to the update, the lock seized up again last night. I sprayed some graphite spray in there, and now it works.
