How do I obtain the Activation Code for my Bluetooth® 4400 or 4401 padlock?

The Activation Code is provided with each lock or lock box in the upper left corner of the instruction sheet, which is located in the package.

If you no longer have the instruction sheet, you can obtain the Activation Code through one of the following options:

1) Visit a Master Lock distributor/retailer

  • Bring the lock to a Master Lock distributor or retailer. The lock must not be attached to anything.
  • Ask the distributor or retailer to contact Master Lock for the Activation Code on your behalf using the Lock/Device ID which is engraved on the back of the lock, or bottom of the lock box, and noted in the app under About This Lock as "Device". The Lock/Device ID starts with the letter A and is followed by 5 numbers or letters. US and Canadian distributors may call 1-800-308-9244.
  • Please note that although Master Lock does not charge for this service, some distributors or retailers may charge a fee.
