Getting a reset code is similar to getting a new password when you forget the old one or change your password in your digital accounts. It would be best to change your combo (short for numerical combination) every few months.

Sometimes people forget to do so. The longer you don’t, the higher the chance for someone else to get their hands on it.

It is imperative if you share the safe with your romantic partner. Any changes in your relationship can lead to a breach in your safe’s security.

I use a fire-proof safe, and after recently knowing how to reset Sentry safe, I pledged to do it every three months.

Steps to Follow Before the Main Part

  • The first step is to check if the battery is dead. If it is not, you input the combo.
  • You can replace the dead batteries through the front panel of the keyboard. A screwdriver can create an opening to change the batteries.
  • Once you have ensured that, turn your safe handle so that it is horizontal, aka the handle points like an arrow towards the number pad.
  • To reset the safe, you have to delete the existing code first.

Resetting Sentry Safe Code (Old Models)

  • Press the ‘PROG’ or program button on older models and type in the factory code two times.
  • Find the factory code in the small card inside the manual you get when purchasing a Sentry safe.
  • After entering it twice, press the ‘PROG’ button and input the factory code again. Now, within five seconds, press a new five-digit code. It is your new user code.
  • You can change this code as much as you want. But the factory code will always open your safe. Sometimes, there is a managerial code that the company managers possess if you need them to open it.

Resetting Sentry Safe Code (New Models)

  • Newer models have a different system for changing user codes. First, like before, you have to delete the previous code.
  • To do so, press the ‘P’ button. And then type the factory code. The factory code is always in the card inside the manual. You can remove the card and store it in a safe place.
  • Now, input ‘00000’ into the safe. it will remove the existing code.
  • Next, press ‘P’ again and press the factory code. Then, select the new combo you want. You can verify and change it as often as you like.
  • However, no one can change or remove the factory code unless you buy a new safe. Thus, never share your factory code with anyone.
