Hello, Dan and welcome.

My name is ***** ***** it will be my pleasure to help.

Yes, you will need both the key and combination to open the safe, so if you don't have your original owner's manual and don't know your combination, Sentry is the only one who can provide that to you, as no combinations are available online for your safety and protection. Follow directions at this Sentry webpage, and you will be able to request your combination:


If you have a 3 number combination, here is the dialing sequence for your safe:

First, turn the dial to the right or left, a few revolutions, to 'clear' it.

A. Start the dial at zero.

B. Turn the dial to the right. Make sure ZERO
passes the pointer at least THREE times. Then stop
at the first number of your combination.

C. Turn the dial to the left. Stop the SECOND
time you reach the second number of your

D. Turn the dial to the right. Stop the FIRST
time the pointer reaches the third number of your combination.


If you have a 4 number combination, please let me know and I will send you the dialing sequence for that.

One note, after using the key, REMOVE it from the keyhole before dialing your combination.

I hope this helps and wish you much good luck with your safe!
