• Restore security quickly - should lost keys or employee turnover compromise your padlock system
• Rekeyable padlocks allow you to remove the old cylinder and either change the pins in it or replace the cylinder with a new one. Then, only the new key will open the lock.
• Save money - replace cylinders instead of locks.
• Master Lock offers (8) rekeyable padlock cylinders.
