Forgot the code for my sentry 3110 safe
3 Digit Combination Lock31-10-31
NOTE: If your safe DOES NOT have a key, skip Step 3.
Turn the dial to zero.
Insert your key and turn it until the plunger pops out.
Turn the dial to the left (counterclockwise) three times to the first number of the combination (pass the first number of your combination two times, stopping on it the third time).
Turn the dial to the right (clockwise) two times to the second number of the combination (pass your second number once, stopping on it the second time).
Turn the dial to the left to the last number (stop the first time on your last number).
Pull the handle down; the door should open.
If this still does not open the safe, refer to the following page for additional different types of safes:http://www.sentrysafeshop.com/kb_results.asp?ID=15
