Lost Combination or Key

Lost your Combination?

For security and liability reasons neither HPI nor Master Lock Company provides combinations to end users by phone, mail or e-mail. However, if the padlock is not secured to anything you may send it to:

  • HPI-On-Line
  • P.O. Box 1326
  • El Cajon, CA 92022-1326

Include a check for $6.00 each. We will then return the locks to you with the correct combinations. Some may find it less expensive to simply purchase new locks, others may find some locks to be sentimental in value.
