I am not certain the question can be answered properly without knowing the model of your safe. The link below is the Sentry Safe webpage for locating manuals. Something there should help.
The second link below is the manual for your safe. I have copied the portion that I think you want.

Models TC8-331 and TW8-331
Access Codes
There are three possible ways to unlock and access the safe—
by entering its preset Factory Code, your own User Code
or a Passcode.
You can always open the safe by entering the 5-digit Factory
Code. But if you prefer to use your own code, you can program
the safe to open to the 5-digit User Code of your choice. If you
wish to give someone else temporary access to the safe, you can
program a passcode that can later be erased.
Programming a user code
There are two ways to program a user code.
A 1. Press the Program key.
2. Enter the Factory Code. The green LED remains ON while
you enter the 5-digit user code of your choice. After 5 digits
are entered the green LED turns OFF.
(To enter a new User Code, repeat these steps.)
B 1. Press the red button inside the safe. The lock will “beep”
and the green LED will come on.
2. Enter a 5-digit user code.
(To enter a new User Code, repeat these steps.)
Programming a passcode
1. Press the Program key twice.
2. Enter your 5-digit User Code. The green LED remains ON.
3. Enter the 5-digit passcode of your choice (any combination
except 00000.) After 5 digits are entered, the green LED
turns OFF.
(To enter a new passcode, repeat these steps. To erase the
passcode, press Program twice, enter your User Code and then
enter 00000.)
To unlock the safe, you must enter a valid Factory Code,
User Code or Passcode. Once you have done this, you have
4 seconds to open the safe by turning the handle or 4-bitted key
to the unlock position. If you fail to do so in time, the lock will
(If you realize you have made an error while entering your code,
press the CLEAR button and start over.)

How to open an older floor model sentry safe?

I bought a home 20 years ago with a floor model Sentry safe that was locked and cemented in the closet of the master bedroom. The previous owners did not have the combination. I forgot about it till recently and want to try opening it! here are the facts
It’s a dial combination lock from about 1970
NO model or serial available as it is cemented into the ground and there is nothing on the face that gives the info just a tag that says SENTRY.
what’s the cheapest way to open it and be able to use it afterwards? If possible.


A locksmith could open it, and put a new lock in. Or just go buy a titanium drill bit about 3/8 to 1/2 inch and drill that puppy out. Use plenty of oil or you’ll break your bit. Might wanna buy 2.

Joseph asks…

I lost my secruity keys for my Sentry Safe. Can I use the keys from one of collegues that has a Sentry Safe?

The safe is a combination safe and the security button that the key goes in was pushed in.


Yes. You can use a diary key. Any small key will open any sentry safe.

Open a 1330 Sentry Safe without combination?

The 1330 Sentry Safe is a combination turn dial safe with no keys.
Does anyone know how to get into it because I forgot the combination. Locksmiths are not an option because I’m too young to hire one and dont have any money to do so.
Or if you know how to get into any turn dial safe without breaking it would be helpful.

Re:Japanese fictional story you deleted (no email)

Put it all in the past tense and minor changes. See what you think

It was in Japan. I was 100 feet away from my troops guarding them as the lone sniper. It was the middle of the night, and as I looked down my night scope, three quarter ways down the road, I noticed three Japanese men walking in the direction towards my troops. As I adjusted my scope to take a shot, I noticed that the third man was an American, being paraded in front to the American troops. I could tell straight away that this was a hostage: he was dressed as a Japanese soldier with a rifle tied to his hands, and his mouth taped shut. The two Japanese men were going to leave him in the open to be killed: one of the Japanese men broke the American soldier’s leg with the butt of his rifle, disabling him from trying to escape. I looked down my scope at the man again, and saw that it was my dear friend Brad, that I had grown up with. I was in complete awe; I thought this man had died weeks ago, he had just disappeared. I saw tears run down his face, but with an expression of no regret. As I saw how brave he was, I remembered how he had saved me from a group of thugs in the back alley of Zesterone’s Pizza Parlor, and years later talking me into joining the army. As I snapped back into the moment, an American soldier shot Brad in the leg. As I saw Brad drop to his knees, I realized I couldn’t let this happen. After all, he had a family to go home to. I moved my scope towards my troops and realized that there was only one man shooting at him. I aimed my scope at his gun, and without even considering this action, I took the shot. His gun flew out of his hands and the rest of the troops started firing their rifles at me. I ducked behind a large boulder avoiding every shot. As the firing ceased, I popped my head out from the side of the boulder, and just as I thought I was in the clear, I heard a metal sound “dink, dink” as a grenade rolled to where my foot was. As I picked it up to throw it in a different direction, it exploded in my hand and nearly killed me. The troops rushed over to me, to finish me off, and saw me lying on the ground. They were all in shock as I said, faintly “Don’t shoot the man across the path. He’s one of us.”

I would change the ending.

The man, I shot the gun away from, spat on my face, pulled out his handgun, aimed it at my head and immediately pulled the trigger. This is how I died. I have no regrets.

The man, I had shot the gun away from, was Brad’s brother. He hugged me and…

Maria Your Questions About Sentry Safe

Maria asks…

Does sentry safe use the same exact key for a model?

Do they use the same exact key for every safe in the same model? I’m just wondering cause my mom bought both my sister and I a safe and it’s the same exact one and i don’t want her being able to get into my safe.


No. It is unlikely that you would have the same keys, but not impossible. Sentry uses a rather large code series for their safes, and your combination should be different as well. If you have no combination, it is simply a small firebox.
