Locksmiths advise these Opening instructions for sentry fireproof electronic security safes. Insert the tubular sentry key into the lock to the left of the key pad. Turn the key all the way to the right until the plunger pops out. Press the five-digit factory code. The green Proceed light will come on. Pull the handle down; to crack the sentry door open.

Hi.

The combination may have been reset because of a malfunction. You need to follow the same procedure that you would follow if you loose your combination. The only difference is that by mentioning that you did not loose the combination the small fee from Sentry support may be waived.

Contact Sentry immediately. They will first try an emergency unlock code, and then they will give you instructions in case the safe must be serviced. Here the contact: Call or Email Us

Here general instructions about what to do when combination does not work. Instructions are addressing lost combination. I know it is not your case. I published the link because procedure followed is similar to non-working combination case. Please call sentry and get the safe open.

Regards.

My Sentry S3807 just will not open. I have the combination right and the key, but it won't open. The batteries could be shot, I suppose, but how do I get in?
