I have a Rhino Electronic Safe. The batteries had gone downand changed them.After applying the Right Code, the Safe is not opened!The Rings are heard as usual. The Safe cannot be opened.

Instructions

1. 1

   Enter your code on the keypad located on the front of the safe. Some electronic digital safes require you to input a special character like "#" before and after your code. The safe should either beep, have a LED turn green, or display "OPEN" if you have correctly entered the code.
   

2. 2

   Turn the handle to the right within five seconds of correctly entering the code. If you wait too long, the safe will lock and you will have to enter your code ag
   

3

Open the safe with a key. Use your emergency key that came with the safe to open it if you forgot the code or if the batteries have died. Remove the key cover from either the handle or the control panel to reveal the lock.

1. 1

   Enter your code to open the safe.
   

2. 2

   Place the electronic digital safe into code reset mode. On some models you need to hold the last digit of the code or press the "*" button to get into code reset mode. Other safes require you to open them and press a small red button on the inside of the door.
   

3. 3

   Enter your new code on the keypad and press "#" to finish. Some safes may require you to press "*" or a letter to finish the code. If the safe requires it, enter the new code again to confirm that you entered it correctly.
   

1. 1

   Use your code to open the electronic digital safe's door.
   

2. 2

   Locate and remove the battery cover on the inside of the door.
   

3. 3

   Replace the used batteries with new ones. For most safes, this will require two or four AA batteries.
   

4. 4

   Test the batteries. Use your code while the door is open to test the batteries before closing the safe.
   

To open your Regent digital electronic safe, you must enter the correct combination code on the keypad and then turn the handle in the direction indicated. to retract the locking bolts and open the door.



If you don't have the combination or the batteries are flat, you can use a rare earth puck magnet. It is faster than using the combination.

if you open your safe you will see on the inside of the door there is a lid that looks like the same at the back of your tv remotes. The batteries are kept inside there. You will find it normally use AA batteries. Hope this helps

I cannot open my Noble safe. I havent used it for 1 year, it has no battery and cant open it with my key. I cant remember the code, but i wont be able ti use it with no batteries.

What can i do

1. The original factory code is 1-5-9 A (or B) to open the safe. There is usually an override key for your safe in case you have lost your code.
2. Once the unit is open, you can reset the combination by pressing the red button, the yellow light will come on. Input a new code 3-8 numbers and then either the A or B button to finish the code.
3. Test your new code several times before locking.
4. If you don't have an over ride key, the first three digits of the serial number should be the key code.
