The 1250 is model of safe that was manufactured by the Sentry Safe company, a subsidiary of Schwab. Opening your Sentry 1250 safe consists of more than just twisting to each number and the safe opening. There is a certain procedure that must be followed to open the safe. After following a few simple directions and practicing a couple times, you should be able to open your Sentry 1250 safe with ease and store or recover your valuable items.
Get the three-number combination for your safe if you have it written down and not memorised.
Twist the dial on the safe counterclockwise twice past the first number of the combination, then stop on the number.
Twist the dial clockwise past the second number, then stop on that number.
Twist the dial counterclockwise to the last number and open the safe.
This can take some practice, so if you miss the first time around, just spin the dial counterclockwise five times and restart at Step 2.
