Sticking lock?
93 90S
I have noticed over the past week that my driver's door lock is acting funny. When I stick the key in, it won't turn, as though the incorrect key is in the lock. I take it out and re-insert it, and sometimes the first time, sometimes the 3rd or 4th time it turns smoothly. Is this a worn lock cylinder, or is it something else? Thanks!

Try putting some waterproof grease in through the lock keyhole.
If water gets in, it can glue up the plates which should slide when you put the key in.
Don't use WD40 or light oil as this eventually dries out and the lock plates will seize up. Only way to fix it then is to take the lock apart.

Howdy! Aside from some graphite lube from the local hardware store you may just want to look at your key. If the key isn't straight sometimes this will cause odd behavoir, don't ask me how I know

Re: I put grease in my lock like you said and now it won't even unlock at all. It's a big gummy mes
Liz, sorry if this has caused you more problems than your original one. Was your lock already sticking a bit to start with ?
You'll have to drive out the excess grease with WD40/petrol distillate spray or something, then put in the graphite lock lubricant that the others have recommended.
The original lock lubricant had to be able to stay in place on/between the plates without drying up or being forced out by constant locking/unlocking.
Unfortunately, if water or de-icer gets into the assembly, this can drive the lubricant off the plates, or else turn it into a paste. Either of these seem to cause the sticking problems. I've taken apart several 'seized' lock barrels and found the hardened white stuff every time.
Since WD40 evaporates too quickly, and light oil doesn't stay in place for long, it needs something with a higher viscosity. Obviously the grease you used doesn't let the plates move at all. Hopefully, you should be able to just spray most of it out again.
Apologies again if this has caused you a lot of trouble.
