Had lost the keys and battery backup for my safe. This is the perfect product to be able to get back in. Also very useful for your phone and many other small electronics. Highly recommend.

Battery died in my gun safe :( My fault, didn't change batteries out after two years. Any how, misplaced both keys. Watched some Youtube videos on how to open safe without having to pay $100s to break in to it. Stumbled upon video using external battery pack with a 3.5mm audio jack that inserts into front door of safe as an emergency failsafe in the event battery dies. When it was delivered, I got it, opened and installed batteries in the pack, prayed, inserted the small jack into the front door of the safe, powered on the battery pack, pressed the pin code as I heard the beeps come alive with every push of the buttons as the green light flashed twice indicating the locking mechanism engage releasing the handle to freely turn and open the safe door. I was SOOOOO HAPPY!!!! :) :) :) As this applies to my battery operated biometric lock mechanism, this is my emergency failsafe emergency key!

This helped me get into a door with an electronic lock after the battery died. It would have been an expensive ordeal otherwise!

This is a piece of absolute junk.

Used for battery bypass on my Patriot safe. I had the safe in storage for a year and the batteries went dead. This unit allowed my to access the safe and change the batteries. What a relief!

The media could not be loaded.

This saved me from cutting into mail box. Batteries fell out inside and this product got me back inside so I could repair. Different connectors make it usable for many product.

It Worked! Was hesitant this would work to gain entry into safe with dead battery and lost key. Thankfully I remembered the code!
