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.

Sentrysafe.comi bought a house with a Sentry 3877. No code only two keys. The prior owners live in Canada

The key generally means you don't need the code. Put the key in, turn it and the door should open. Press the reset button on the back of the door and reset the code. I would change the batteries whilst you are in there. The key is for use when the batteries run down.

Why won't my safe open? I have 3 keys that fit, door won't open . I don't know combination.

There should be a serial number on the safe. You can google the manufacturer and get a contact number, call them and they will be able to walk you through resetting the combination. But it sounds like you will need to replace the battery in it first

Manual for stramm digital electronic safe manual

The Stramm safe we have is a small one that we use to store keys for our drivers. To change the combination, open the safe with the current combination. Sorry, can't help you if you don't know that. Inside the door is a plastic panel covering the batteries. Pinch the plastic catch at the top and open the panel. There is a small red button which you can press to change the combination. When you press it, you will hear a double beep. Enter your desired new combination. The trick is that the last digit must be either an "A" or a "B" which signals the end of your combination. For example, if you want your new combination to be 123456, you can't do that. The closest you can come is 123456A or 123456B. Hope this helps. Steve, Mbeya, Tanzania

slide open the battery cover located just below the keypad.

I own a Bunker Hill digital floor safe sku #need code change data

To change the code: Your safe comes
preset with the default code of “159-A”.
To change the code, first open the safe.
On the inside of the door near the hinge,
there is a small red “reset” button. Press
this button until the Yellow LED on the
front panel lights up. Now, input your new
code up to 8 characters, followed by
either “A” or “B”. The Yellow LED will flash
to indicate that your new code has been
accepted. Warning: If the Yellow LED
does not flash, the code has not been
accepted, and you must start over.
NOTE: Be sure to test your new
combination before closing the door.
NOTE: Be sure to have the Override Key
available when setting a new
combination or changing batteries, in
case the door doesn’t open.

Good Luck

Need to open a Sentry keyless combination safe

First, has the factory combination been changed? Sentry has the code for the factory combination that they can supply you.

If the factory combination has been changed to something else, then Sentry won't have it.

In that case you need to ask Sentry for a 'reset' code combination. There is (at least) one back door to your safe -- a reset code.

The reset code will not tell you what your combination is, it will simply reset the combination to the factory combination.

You can take it from there.

Now, this isn't as hard as it may sound. There is an actual department that handles this at Sentry because you aren't the only one that cannot open his safe.

They'll want some proof of ownership, some $$ for the service, the safe serial number, and probably a notarized form claiming that the safe is yours.

Get 'hold of Sentry on the web and the rest is just process.

BTW -- this is exactly what the locksmith would do.
