Old Sears safes have a combination dial variety due to their age; safe dial pads are a new technology. Combination dial safes follow a pattern that consists of several dial turns to specific numbers that are safe specific. Utilizing this standard information, you can pair your combination with the proper dial turns and gain access to a safe. You should, however, only attempt to gain access to safes which you own to avoid legal repercussions
Find the combination to your old Sears safe.
Set the dial to 0. Turn the combination dial to the left four times and stop on your first number.
Turn the dial to the right three times. Stop on your second number the third time.
Turn the dial to the left twice. On the second turn, stop on your final number.
Turn the dial to the right until you get to 0.
Invert the direction of the dial turns if starting to the left does not work. Extremely old safes started by turning right, then left, then right, then left.
Contact Sears customer support with the proper serial and model numbers if you cannot open the safe at all. They may be able to help you find a way to open the safe.
