- Reassemble the lock: Carefully put the lock back together, ensuring all components are correctly aligned.
- Test the new key: Insert the new key to verify that the lock operates smoothly.
Tips for Effective Rekeying
- Always double-check pin sizes against the bitting chart before installation.
- Keep spare pins organized for quick access during rekeying.
