To open a Sentry safe with a combination lock, the general procedure is as follows:
- Turn the dial to 0.
- Turn the dial clockwise (right) three full times passing 0, then stop at the first number of your combination on the fourth turn.
- Turn the dial counterclockwise (left) passing the second number once, then stop at the second number the second time it appears.
- Turn the dial clockwise (right) again directly to the third number of the combination, stopping there on the first try.
- Turn the handle downward (or turn the knob) to open the safe door.
If your safe model also has a key, insert the key into the keyhole, push in, and turn to the unlock position before dialing the combination. If you have a digital Sentry safe that won't open with the code, it may be a battery or solenoid issue. Check and replace the batteries including the auxiliary 9V for emergency power as needed, or consider expert assistance if it remains stuck. For safes that are physically stuck or without combination/key access, it is common advice to consult a professional locksmith for safe opening or repairing rather than forced entry, to avoid irreparable damage. This step-by- step method applies to most mechanical combination Sentry safes and is essential to follow the correct turn counts and directions for the combination dial to unlock the safe properly.
