Can I use this lock on other items besides bikes?

Yes, the lock itself is a standard padlock and can be used on sheds, lockers, or gates. The included mounting bracket is specifically for bikes.

What should I do if I lose the key?

Master Lock offers a key replacement program. Note the key code (if available) or contact Master Lock customer support with your lock's serial number. You may need to provide proof of purchase.

Are replacement screws or PVC pads available?
