Question about Master Lock 5400d: Portable Select Access Key Storage Lock
A friend just gave me this type of lock but couldn't remember the combo. I see a reset button but I haven't been able to get it to do anything. Any suggestions??
The reset works when the current correct combination is set on the front. If you forgot the combination, you can go to the www.masterlock.com and download a PDF to request a combination from the factory to open it. It requires a notarized form & takes 6+ weeks. In the end, it is probably easier to buy a new one. When resetting the combo, I accidently scrambled it as I flipped it over. And did not know the combo. The reset button would not work. I did some guess work around the setting and got it to release again.
