Gummy Locks

I dont know if its the weather. or the lock itself. it feels kind of gummy. like not as smooth as a normal lock. and sometimes i cant even move it. sometimes i can. i never have a problem with the passenger side lock, works great. no matter what kind of weather there is. and definetly feel fine. should i get into the door and spray the lock and the whole system in there. or is it just the weather and will it pass once it gets warmer out?

It is quite possible that the lube inside the lock cylinder has gotten some crud inside it. Get a can of lock deicer and spray it. The alcohol will clean it then spray some lubricating oil inside the lock like wd-40. That should correct the problem.
