1. Check for Door Pressure First
If the door is pulling against the latch, the key may not turn even when the cylinder is fine. Pull or push the door slightly while turning the key to relieve pressure.
2. Inspect the Key and Keyway
Look for bent keys, debris, or worn key cuts. A worn copy often causes intermittent jams. If the key is damaged, stop and use a clean original key.
3. Use Lock-Safe Lubricant
Use graphite-free lock lubricant made for commercial cylinders. Avoid heavy oils that attract dust and make jams worse.
4. Test Latch Alignment
If the key turns but the bolt sticks, the strike may be misaligned. This is common on high-traffic doors where hinges or closers drift out of adjustment.
5. Escalate if the Lock Binds Repeatedly
Repeated jamming usually means cylinder wear, latch failure, or frame alignment issues. At that point, request professional service to prevent a full lockout.
When to Call Immediately
- Key snaps in the cylinder
- Door is the only legal egress route
- Storefront cannot secure at close
- Lock jam follows a break-in attempt
