Prosafe PSF300 is electronically unresponsive. Manually opened safe with physical key, changed batteries and read the manual twice. Safe door refuses to close/lock and key pad and card swiper are unresponsive. Thanks for any assistance you may provide! - Isaiah ([email protected])

Here are a few steps you can try to unlock your Nutool SF20 electronic digital safe:

1. Double-check the battery installation: Make sure the batteries are correctly installed and not dead.
2. Try the default code: Many safes come with a valuable default code in opening the safe when you forget your code or if the keypad stops working. The default code is usually found in the manual or inside the safe door.
3. Check the locking mechanism: Make sure that the locking mechanism is not jammed or stuck. Try manually moving the locking mechanism with a screwdriver or other tool to see if it will release.
4. Use the override key: If your safe has an override key, insert it into the keyhole and turn it to the left or right to open the door.
5. Contact the manufacturer: If none of the above steps works, contact Nutool customer service. They may be able to provide you with additional troubleshooting steps or advice, or they may need to send a technician to repair or replace the safe.

Usually there is a compartment on the inside of the door that holds the batteries.

INITIAL BATTERY INSTALLATION
1. Remove the key plate cover, insert the key into the keypad and open the door.
2. Remove the battery cover plate located on the inside of the door.
3. Install 4 AA batteries provided and replace the battery cover.
NOTE
: If both the red and green lights are on while the safe is open, this indicates that the batteries are low and need
to be changed.

TO SET UP OR CHANGE A USER CODE
1. With the door open, locate the red button on the back of the door near the hinge.
2. Press the red button and listen for the beep.
3. Immediately enter your new passcode (3-6 digits long)
4. Immediately after entering your new passcode, press the "A" or "B" button on the keypad. Your new user passcode is now stored.
NOTE:
This safe stores up to 2 passcodes (a user code and a manager code). Entering a third code will erase the
first passcode entered.

SETTING UP OR CHANGING A MANAGER PASSCODE
1. Open your safe with the passcode you wish to change and leave the door ajar.
2. Press the "0" button on the keypad twice. Press the red button, listen for a beep and then enter your new user passcode.
New user passcodes may be 3-6 digits long.
3. Immediately after entering your new code, press the "A" or "B" button on the keypad. Your user code is now changed.
OPENING THE SAFE
1. Input your code and then press the "B" button, the green light will turn on.
2. Turn the knob clockwise within 5 seconds to open the door.
3. Each key pressed will be accompanied by a buzzer and a yellow flashing light. If the entered code is invalid the yellow light will
flash and the buzzer will quickly sound, this indicates the code needs to be re-entered.

CAUTION
: Entering the incorrect passcode 3 times will lock the system for 20 seconds.

There are two ways you can open this safe. First one is to give alternate power supply for which generally a devise is provided which I do not think you have the access to. Second Option is that you must have manual override keys. With this manual key you can open the safe and then change the batteries.

The Stramm safe we have is a small one that we use to store keys for our drivers. To change the combination, open the safe with the current combination. Sorry, can't help you if you don't know that. Inside the door is a plastic panel covering the batteries. Pinch the plastic catch at the top and open the panel. There is a small red button which you can press to change the combination. When you press it, you will hear a double beep. Enter your desired new combination. The trick is that the last digit must be either an "A" or a "B" which signals the end of your combination. For example, if you want your new combination to be 123456, you can't do that. The closest you can come is 123456A or 123456B. Hope this helps. Steve, Mbeya, Tanzania

After opening the electronic safe (with the pre-set factory code of 159B) locate the small red button on the
inside of the door near the hinge.
2. Press the red button and then release it, you will hear a beep. DO NOT SHUT THE DOOR UNTIL YOU HAVE CONFIRMED THAT YOUR NEW SECURITY CODE HAS BEEN ENTERED CORRECTLY.
3. With the door open, enter your own personal security code, which can be 3- 8 digits long, and confirm your new code by pressing the letter “B” on the electronic touch pad. Before you close the door, try the new security code to make sure the lock release the knob so you can turn it and retract the live action locking bolts.
If the code fails, go through steps 1-3 again. If the code works successfully, then you should lock the safe. When you open the safe in the future enter the security code you have set followed by the letter “B” and turn the knob.

If the incorrect security code is entered 3 times you will have an automatic lockout for 20 seconds before you can try your code again. If the incorrect security code is entered 3 additional times there will be a 5- minute lockout before the code can be tried again.
BATTERY REPLACEMENT
This safe uses 4- AA batteries. Under normal use, batteries will last about 1 year. When the battery is low, a red light will come on warning you that the battery is low. To test the batteries, enter your security code. If the batteries are low the red light located in the middle of the top of the keypad will start to flash.

To replace the batteries, open the safe door with your security code and turn the knob. Push the batteries cover plate, which is located on the back of the door, and replace the old batteries.
YOU MUST PROGRAME YOUR SECURITY CODE AFTER YOU REPLACE THE BATTERIES. SEE STEPS 1- 3 UNDER “ENTERING YOUR SECURITY CODE”.
TROUBLE KEY
A “Trouble key” has been provided in case you forget or lose your security code. Remove the small central panel from the front of the faceplate. Insert the key and turn it counter clockwise. Then turn the knob on the door towards the right. This will manually open your safe. If you lose your key, you may purchase a replacement key by referencing the serial number located under the central panel by the lock.
MAINTENANCE FOR KEY AND ELECTRONIC SAFE
If the door of the safe starts to rub on the door frame, open the door per the instructions above. By the door hinges you will find a threaded stem. Use an Allen wrench to tighten the threaded stem. This will help realign the door and give you trouble free access to the contents of your safe.

I need an instruction Manual for a Nutool sf20 safe

The operating instructions on the ES20 as per the crappy manual:

Open safe using emergency key provided

Insert batteries in the box inside the door

Opening the safe
a. pre-set factory code 159
b. input 159 (the yellow light will flash and the buzzer will beep), then press B or A button, the green light will be on, rotate the knob clockwise, pull outwards, the door is opened

Closing the safe: close the door, input the code (the green light will flash for 5 secs). Turn the knob anti clockwise, the control system will activate and the safe will be locked

Changing the code: open the safe, press the red button located inside the door, the yellow light will go on indicating the code can be changed. Input the new code (1-8 digits), then press A or B button, it shall be confirmed by two beeps indicating the new code has been accepted and stored. If the yellow light and buzzer beeps 3 times the code is invalid - try again

Emergency Key - store in secure place NOT inside the safe. Remove the override cover in the centre of the face of Safe (its a silver plastic panel with Sandleford Electronic Safe ES20 on it), insert override key (a cyclinder key) - hidden underneath the override cover panel - and turn anti clockwise, rotate the knob clockwise to open door

Changing the Battery - If the red and green light are on this indicates that the batteries are low and require changing. To ensure the batteries have been installed correctly test before closing the door
