Repair a lock myself
Can I Repair a Lock Myself?

If your key is hard to push into the keyhole, or takes extra force
to turn, this is an easy type of repair to do yourself. To tackle
this repair, purchase a small tube of graphite powder, available at
hardware counters where keys are made. Simply squeeze a little
powder into the keyhole. Now you should be able to insert and turn
the key easily.
Deadbolt Lock Repair
Another easy repair is a deadbolt lock that doesn't latch
easily. As a consequence of settling and temperature variations, a
deadbolt lock may not match up with the door frame anymore. To
repair, file the door frame hole a little bigger so the latch
slides in easily
Car Door Lock Repair
Depending on your level of comfort, you may be able to handle
the repair of car door locks yourself. Perhaps one door doesn't
lock or unlock anymore, or your electronic lock control doesn't
work on one door. You may be able to diagnose and repair the issue
with the help of your vehicle's manual, online resources, and
advice from staff at an automotive parts store. The repair may be
as simple as replacing a broken wire or the entire door lock
actuator.

an arm and a leg. But if you attempt to remove the key yourself,
you're likely to do more damage to the lock in the process. Now the
cost is more than a simple repair-you have to replace the entire
lock and get new keys.
