How to Open a Stack-on Gun Safe Combination Lock

Stack-on Gun Safe Combination LockStack- On has over 40 years rich history of manufacturing and distributing gun safes in the United States. They have been making gun safes to suit both the residential and commercial market.

With changing and improving technology, Stack-On has integrated the advances in the security sector to come up with new and improved safes for their clients.

Among the different parts of a safe, the most important one is the safe’s lock. It is the primary source of security. As safe manufacturing technology has improved, so has lock construction technology.

Different versions of Stack-On safes have different types of safe locks. This translates to different safe unlocking mechanisms and procedures. The following are the most commonly used Stack-On safes and their opening procedures and mechanisms:

This is among the advanced Stack-On safes. It uses biometric data to unlock. The following is the process of first time opening of the safe and subsequent unlocking procedure of this Stack-On safe:

  • A new safe comes without biometric data and the first process after opening the safe is to input your biometric data. It is recommended that you use only your thumb or index finger as default fingerprints.
  • To open the safe, you place the finger that you used in recording your biometric data on the scanner. A blue light will flash with a beep and scanning commences.
  • If the biometric data is accepted, the scanner will produce two green flashes indicating that you can pull the handle to open the safe door. You have exactly five seconds to open the safe door or the locking mechanisms will re-engage.
If the scanner produces a red flash, it means that your biometric data has not been accepted and you have to try again.

If incorrect biometric data is presented three times in a row, the scanner produces 5 flashes accompanied by 5 beeps. This is followed by a 60 seconds shut out where the safe cannot be accessed.

If another incorrect fingerprint is presented, the safe produce another 5 flashes and beeps and executes a 5 minute shut out.
