Hi Edward,

If you have forgotten the code for the knob then there should be a master code available from the manufacturer.

Please let me know the make and model number so I can assist you further with this.

Sentry it has two numbers 80410. An 080559

Thanks for that;

if the master code is not written in the booklet, then you will need to call Sentry on ***-***-**** or contact them through their online Contact form to request your combination:
