Before You Drill...

Refer also to the booklet Dialing Diagnostics by Brian Costley, S&G.
1. Run the combo with all numbers one number low. Example: Combo should be 50-25-50, run 49-24-49.
2. Try one number high.
3. Continue in 1/2 number increments up to 3 numbers off in either direction.
4. If the door opens using one of the above methods, check if the users tend to spin the dial rapidly. If so, this will cause tumbler wear and combo drift.
5. Once the door is opened, the combo should be changed and tested before being shut.
6. If the door cannot be opened, it must be drilled.
