How to dial open a "Direct Entry" three wheel combination lock used on Sentry Fire Safes. For safes with a four wheel direct entry lock, the procedure is the same but you have to dial four times to the first number, three times to the second number, twice to the third number and once to the final number. Whilst you always reverse direction for alternate numbers please note that some safes are set up to start dialling clockwise and others start anticlockwise.
