How do I change my Masterlock code?

Changing the code on the Master Lock 5401D is very simple. The pre-set factory code id 0-0-0-0. Just open the hinged door and on the inside of the door you will find a small reset lever - Push the reset lever left and down. The lever remains in this position and then you are able to move any or all of the 4 number wheels so that your preferred code aligns up centrally on the dial. Make sure they are definitely aligned correctly and then move the lever back to it's original position you can then close the door, move the wheels randomly to lock the safe. The new code is now set.

Question asked by Freya Scott on 9 Dec 2016

Code has been reset as per instructions but won't open. Think mistake made on intended code. Can we override to open??

To ensure security there is no master code and I doubt it would be possible to design one on a mechanical lock. Unfortunately unless you know the code you set or are lucky enough to stumble upon it then there is no way in.

Question asked by Elaine Edwards on 27 Feb 2017

I am wanting to fix this over a lift button so that only authorised people can operate the lift. I want to cut out a square in the back panel of the safe in order to expose the lift button when the safe has been opened. Do you think this adaptation is possible? What is the back made of? is it metal or plastic?

The body of the Master Lock 5401D Key safe is manufactured from Cast Aluminium, which would be difficult to cut in the way you describe. I guess you would need to speak to a Locksmith if they couild do it for you. The other issue is how much space and how far the button would protrude into the safe so allowing the safe door to be closed and also to allow the safe to be secured to the wall.
