Annual Preventive Maintenance Protocol
Lock cylinders in commercial facilities require scheduled annual maintenance to prevent premature pin chamber galling and key sticking.
Recommended Procedure
- Blow Out Debris: Use compressed air to blow key shavings and dust out of the keyway.
- Apply Dry PTFE Spray: Inject a 1-second blast of dry PTFE micro-lubricant into the keyway.
- Cycle Key: Insert and rotate the key 5 times to distribute the dry PTFE film.
- Never Use WD-40 or Oil: Liquid oils attract grit that creates abrasive grinding paste.
