Master Lock Locks & Locksmithing - Page 4 - Recent Questions, Troubleshooting & Support

I don't know if Master Lock will supply a combination or not but they can open it for you. There might be ownership issues that need verified. They don't know who's keys are in it and they don't know if the lock has been stolen.

Forgotten my combination, how do I open and reset a new combination??

Two solutions: (if the box is closed and it is attached to something)1. Contact Masterlock.com and fill out the form, get it notarized and send it in for the combination to unlock it based on the S/N which is on the lock.(http://www.masterlock.com/faq/LostCombinations/). Good luck on this since Masterlock will end up finding something that will prevent them from giving you the combination. Its quite frustrating and NOT worth the trouble.2. Go to home depot. Buy a 24in bolt cutter ($22) cut the stem of the lock. and replace with a new lock that you can buy from home depot for $ 29.00. If you have a key that is inside the lock box that you really need, You will now need to drill out the combinations piece by piece and the door will pop open or send the lock back to Masterlock. They will retrieve the key for you and send it back.
