Driver's door lock getting sticky

Noticed it a few days ago, and it's getting worse each time I unlock it... the key feels like it's working its way through sludge, and I just know that one day in the very near future it aint gonna work at all. Anybody had this happen? How did you fix? 44K miles so the bumper to bumper is expired. 2015 AC.

 

Maybe just need to lube things up a bit?

 

lock lube at autozone

or take door apart and lube it all

 

Graphite lube

 

Give it a lube job.

No need to order online. Almost any parts house or home improvement store will have this or similar.

 

Go to a bicycle shop and get some Tri-flow. It comes in aerosol cans with a little plastic straw. Perfect for getting in the lock cyl

 

Thanks all for the input. Maybe a dumb question, but no worries with the lube screwing up whatever electronics are involved with the lock?

 

Nope. The servo is a bit aways from the key mechanism and the door gets some water in it anyway.......... (it's why there are drains at the bottom)

 

Cool. Thanks again all.

 

Dude, use some tissues to clean up afterwards. Sheesh!

 

Mine was getting stiff so I sprayed some Fluid Film in. (They advertise it safe for locks and doesn't freeze up). Super smooth now. Figured things are probably corroding in there anyways.
