I have a ce electronic system safe for which I have two keys. I dont remember how to use the combination battery operated code any more as I have lost the instructions. Can I download these instructions from the internet anywhere? The keys have 128 written on them but I cannot find any further I.D numbers anywhere. Thankyou very much for your assistance

The key should open the safe in any circumstances.

All safes of this type have a 4 number combination.

They are very insecure and can be open using a Rare Earth Puck Magnet. Then you can remove the batteries, and reset the code.

I think you have given us the Serial Number not the Model Number?

The factory code combination to your electronic lock will remain in the memory of the unit - even if the batteries go dead. Any use programmed codes will be lost if the batteries lose power. The Sentry programmed factory code is always your default code.

If you do not know your factory code, you can follow this link for your combination retrieval:
