It may be possible to obtain replacement keys for your lock ONLY if you know the key number. The key number is stamped on the original keys provided with your lock. If you do not know the key number, it is possible to obtain additional keys from a locksmith who can impression your lock. If you do know the key number, go to a locksmith or local hardware store to order keys. Please note that the locksmith will charge you a fee for this service. Not all Locksmiths, Hardware Stores or Home Centers offer this service; please phone ahead.
