How to Fix a Rusted Padlock
It has been locked up outside all season. It needs a little persuasion.
Outdoor padlocks seize from rust in the shackle holes and grit in the keyway. Penetrant frees them; a dry lock lube keeps them working.
Step by Step
- 1
Spray the shackle holes
Spray penetrant into both holes where the shackle enters the body.
- 2
Spray the keyway
A short burst through the straw into the keyway.
- 3
Work the key gently
Insert the key and work it back and forth. Tap the lock body lightly with a small hammer while turning.
- 4
Flush and switch to dry lube
Once it opens, work the shackle a few times, then use a dry lock lube so the keyway does not collect grime.
No heat. It does not help a lock and can damage it.
- If the key twists, stop. A broken key in the keyway is a worse problem.
