Residential & Commercial Security - Locks, Keys & Dead Bolts - key sticks

I have a deadbolt and regular lock-door knob on a security door. I washed down the door yesterday and now I can't seem tofit my key into the locks. My key works on all the other locks.
Will WD-40 help with this problem or am I going to have to replace the locks.

THanks

You may have washed some debris into the keyway. Try a vacuum cleaner to see if you can suck anything out. A blast of graphite will help lubricate the lock. Liquid lubricants tend to attract dirt and so make things worse. You might try some lubricant such as WD40 on the key. I would not spray it into the lock. If this fails, take the locks out and to a locksmith and see if he can clean them for you.

I prefer using Tri-Flow, which has Teflon. I recommend WD-40 only in a pinch as it tends to be a bit thick for locks in my experience but it should get you working. Another locksmith I know prefers dry spray lubricants with Teflon(without the petroleum distillates). I think this is the best way unless you need to flush crud out of the lock.

For now I did try the WD 40 and it worked, but I think I will take it apart and see if I can clean it or try one of those spary cleaners for computers.

Thank you

If it's not broke don't fix it... might apply. I had someone bring me a lock that her knucklehead husband (her words not mine) and his brother tried to disassemble and fix and they mixed the parts up. If the key works good, the pins are moving freely and that is all you need.

Depending on the lock, I will lubricate the latch also and possible some main friction points at the thumbturn and/or knobs. Chfite is correct when he warns to be careful with the liquid lubricants, they can leave residues that can hold dirt. Always wipe up any excess and try to avoid it in the first place.

Most residential locks rarely get dirty enough to warrant a disassembly to clean.
