I have a Paragon safe with a keypad that's battery powered. And the batteries aren't strong enough to open the door when I punch in the code. I have lost the key to open. What options do I have?

It is quicker to open it with a rare earth puck magnet that it is to enter the code! Paragon, Sentry Safe, all the same.

So the girlfriend got inside first and took all the good stuff and left the door open with the locking bolts out and deployed? :>(

Page 3 of the manual. You press the red reset button and change the pass code to a new one. Change the batteries as well at the same time. This is the better manual. Other left below

If the key is not working, then unfortunately you will need to call a locksmith to open the safe. There is no other way to open the safe without the key.

heres a copy of the manual for this safe , but if it wont lock back its probably telling you the battery's are low

Leave it for a week. The batteries might have regenerated just enough to open the door once more.

Otherwise there may be a keyhole beneath the front plate.

If all else fails, you'll have to cut the back out of the safe.

The problem you have is a weak signal that is not strong enough to penetrate the door. Make sure the battery is good. If not the battery then a new keypad will be needed.

If you are sure the battery is good you have a bad keypad. The signal strength is so weak it will not penetrate the door.

IF REPLACING THE BATTERY DOESN'T DO IT YOU WILL NEED TO REPLACE THE KEYPAD.

NOTE: (IF YOU HAVE A ROLLING CODE SYSTEM) YOU WILL NEED TO REPROGRAM THE UNIT AFTER YOU CHANGE THE BATTERY.

HOPE THIS IS HELPFULL
