SOURCE: Forgot Digital Combination of Sentry Safe Model #SO500

They should be able to help. I would try calling first, to avoid paying the $12 to retrieve the combo, but with the serial number of the safe, they SHOULD be able to help you over the tele.

SOURCE: know combination, but cannot open sentry safe 1250

If you know the combination:

1) Turn the dial to the left a few complete rounds, then stop on 1st number.
2) Turning the dial to the right, pass up the 2nd number once, then stop on it on the next round.
3) Turn the dial to the left directly to the 3rd number then stop.

The handle should open now.

Sentry S 3110. Combination lock with 3 numbers. How do I open it?

First insert the key into the lock, if there is a keyhole, and turn it until the plunger pops out. (You must have the key to unlock the safe for the keyed version of the safe.) Remove the key.
Set the dial to zero. Turn the dial to the right (clock-wise) three times (pass zero three times) then stop at the first digit in the combination. Turn the dial to the left twice and stop at the second digit given in the combination. Turn the dial to the right again and stop as soon as you reach the third digit. The safe should open.

Sentry has the manual available for the S3110 safe on the product page: . The direct link to the manual is . The directions for opening the safe are on page 2.

If you do not have the key and your safe has a keyhole, you probably need to contact Sentry or a locksmith.

I hope this helps.

I have a Honeywell 1.06 cu #2072 safe, the keypad has been broken off and the override lock is gone

I'm sorry that sounds like a bad day. You could always just find someone to finish the job and crack it? I have not had the most experience but maybe a last resort?

What's is the standard preprogramed code for smartcode locks

If there was a standard preprogrammed code for locks, given that there are many people either too lazy or too stupid to reset their own unique lock code, thieves would be having a field day. Therefore, there is no standard preprogrammed lock code, for digital locks or digital safes.
