Stack On/Sentinel Replacement Lock Cylinder

Replacement key lock for Stack-On/Sentinel Gun Safe Products

  • Brass finish
  • Mounting hardware included
  • 2 keys per order
  • These are OEM Stack-On key locks. We are told they also work in Sentinel gun safes with locks that look like this one.

Easy standard replacement for all current production Stack-On safes. Older models may require a small amount of modification with a dremel tool to make the lock opening a little bigger. This is the only key lock Stack-On is now offering for gun safes. The old style is no longer available.

Please note the following:

  • This lock is for stand up style gun safes only. Not for other Stack-On safes or pistol boxes. 
  • We can not obtain any other types of Stack-On locks.
  • We can not provide or obtain locks keyed to a specific key any more. All locks are chosen randomly.

    Broke Immediately

    Upset that this lock fell into dozens of pieces when I opened the bag and picked up the lock. I guess the piece that held it together loosened during shipping.

    Good Product

    Fit like new. I like being able to order a specific key number to make both cabinets the same. No modifications required for my install. The only negative was the new cylinder did not come with mounting hardware, but safe and lock has promised to make that right. I used the existing nuts and washers for installation.

    Note from
    This item was shipped direct from the factory because of the specific key number desired. We have sent the missing hardware ourselves so there will be no long wait! Enjoy your keyed alike cabinets and thank you for the review.
    Hope Tucker

    Option to have multiple locks keyed the same is great.
