Looking for your Sentry Safe’s Factory Code, Dial Combination, or Key Number?
At teklib.com, we often get requests for Sentry Safe user manuals — mostly from people hoping to find the factory code, dial combination, or key number for their safe.
It totally makes sense. After all, the manuals say things like:
” … the factory code (printed on the first page of this guide)… “
” … your safe’s combination is printed on the front of this owner’s manual… “
” … factory code provided on the front of this manual… “
” … found on the front cover of this guide… “
” … the sticker on the front of the owner’s manual contains the factory combination… “
So naturally, you may think: If I download the manual, I’ll get the code!
But here’s the truth you need to know.
The manual you can download in electronic PDF format doesn’t actually contain the code.
The user manual you can download from teklib.com (and other places) is just a general instruction guide for your type of safe.
It includes a spot on the first page where a sticker would be placed by the manufacturer — with the unique factory code for your specific safe.
That spot looks something like this:

In reality, the actual factory code / dial combination / key number is printed on a physical sticker that’s only found on the original hardcopy of the manual that came with your safe when you bought it.
Here are some real examples from Sentry Safe owners:

As you can see, these codes are unique for each safe.
They are not printed in the manual itself, and they’re not included in any digital (PDF) version you download.
So what can you do If you’ve lost your factory code?
Here’s what Sentry Safe says:
If you lose your combination or keys, we can help!
Your safe’s serial number is required to obtain a replacement.
So if you’ve lost your factory code, combination, or keys, the best thing to do is contact Sentry Safe customer support:

A Quick Note About Ownership
Keep in mind — before they give you a combination or replacement keys, Sentry Safe (or Master Lock) will likely ask for proof that you’re the actual owner. That’s to protect you — and others — so someone can’t just try to access someone else’s valuables.
If you’re just looking for the instructions on how to use your safe, feel free to download the manual for your model at teklib.com.
But if you’re trying to recover your code or combination — your best bet is to contact Sentry Safe support directly.
