Hi, thank you for contacting JustAnswer.com. My name is***** will do my best to provide the right answer to your question.
What is the safe doing, or not doing, that makes it seem to need a reset?

Customer: replied 2 months ago.
it will not open if Iam doing the key right it will not open with it
Expert:  Russell H. replied 2 months ago.

Does the green light show, when you enter the right code or combination?

Customer: replied 2 months ago.
When it is the right code it will
Expert:  Russell H. replied 2 months ago.

OK, then. When were the batteries in the safe last replaced, is the next question that needs to be asked. ?

Customer: replied 2 months ago.
Last year
Expert:  Russell H. replied 2 months ago.

OK... I advise first, checking the batteries to see if they are leaking, and trying new batteries.

After that ... if you get a green light, you have entered the right code, and the safe is not opening for other reasons than the code or combination. Let me know if the batteries are replaced, there was no brown corrosion leaking from the old batteries, and the safe still won't open... there will be more to try then.

Ok thanks

Got safe open need to change combination now
Expert:  Russell H. replied 2 months ago.

Good. ...

Expert:  Russell H. replied 2 months ago.

The AJ-839985 number that you mentioned is apparently a serial number. Please tell me the safe's model #. Or, if you cannot find it, then tell me whether it is a dial safe or a combination keypad buttons safe, and whether it has a keylock on it (I think you mentioned a key) and whether it is a Fire Safe, a Floor Safe, or some other type.

Customer: replied 2 months ago.
It has a key lock and key Pad it's not a floor safe
Expert:  Russell H. replied 2 months ago.

Right. But still, to give you instructions on changing the combination, it would help to know the safe model, please. Otherwise we might be dodging about with wrong instructions that don't work on your model, for quite some time.

Customer: replied 2 months ago.
This is the only other number I could find 83877
Expert:  Russell H. replied 2 months ago.

Could that be read as S3877 ? if so that's a valid model #...

Customer: replied 2 months ago.
Expert:  Russell H. replied 2 months ago.

Good. I am preparing an answer for your question about changing the code on the safe.

Expert:  Russell H. replied 2 months ago.

To wipe all codes from the safe except the factory code, when the safe is open, press P, then enter the factory code, then enter

0 0 0 0 0

Then, to set a new code, you in some cases press a button on the inside of the door, then enter the new code and press #.

See if that works.

Customer: replied 2 months ago.
Ok
Expert:  Russell H. replied 2 months ago.

Did it work? if you don't mind telling me.

Customer: replied 2 months ago.
I have to go 6 blocks where it is but I don't have the factory code that was the problem don't have the book
Expert:  Russell H. replied 2 months ago.

I see. So what code do you have? a user code? then you cannot change it.

To get the factory code, if you have lost it (or the original booklet for the safe that it is usually written on) you will have to be the original owner of the safe, and apply to Sentry Safes or Master Locks (which now owns Sentry Safes) to have it re-issued to you.

Customer: replied 2 months ago.
We purchase the safe at Walmart I know the code we. Started with but. Just wanted to change it for security reason. We have two. Many with this code.
Expert:  Russell H. replied 2 months ago.

OK. But if that's the factory code, you cannot change the factory code, and if you don't have the factory code, you cannot change any code, pretty much.

Do you want the procedure to go about applying for the factory code?

Customer: replied 2 months ago.
Not sure thanks for your help
