Common Faults and Troubleshooting Methods for Electronic Safes - The Most Comprehensive Guide Online

2025-11-04

To avoid property loss, many families now choose to buy safes to protect their family assets. However, safes encounter various problems during use, the most common being that they cannot be opened. What should you do if you urgently need to retrieve an item from the safe, but it malfunctions? Henan Huadu Times Furniture will tell you how to solve safe malfunctions.

Common problems encountered when using safes:

1. Why can't I insert the key into my electronic safe or turn it all the way? A: This is usually because the lock chip in the main lock's leaf spring mechanism is not engaged, preventing the key from being inserted or turned fully. You can use a flathead screwdriver to turn it counter-clockwise 7-8 times to solve the problem.

2. My electronic safe's LCD screen isn't displaying anything. Is it out of power? A: Each safe comes with an external battery box and a spare key. You can open the safe and replace the batteries yourself using these accessories. 3. Forgot the password for my mechanical safe? A: To protect your property, when you need to retrieve the password for your purchased safe, you need to provide the safe's model and serial number, and fax a copy of the ID card of the person retrieving the password to our company. After verification and filing, we will provide you with the password retrieval service. If it's a safe used by a company and you've forgotten the password, please call the 400 or 800 customer service hotline on the website homepage for assistance. 4. My electronic safe isn't responding after installing new batteries? A: First, check if the battery's positive and negative terminals are installed correctly. Second, check if the springs at both ends of the internal battery box are rusted. If everything is normal, call the repair hotline to have after-sales service personnel come to your location for repair. 5. What should I do if I forget the password for my electronic safe or made a mistake while changing the password? A: First, find the emergency key to open the door. On the inside of the safe door panel, there is a small hole covered by a plastic part. The factory reset button is inside the hole. If there is no pre-drilled hole, you need to remove the cover to find the circuit board. There is a small black button on the circuit board, which is the reset button, and you can reset the factory password.

6. Why can't the electronic safe door close? A: This usually happens when the door isn't opened properly. If the handle isn't fully pulled back, the latch and bolt will pop out automatically, preventing the door from closing. First, pull the door to a 90-degree angle with the closed position, then use the combination key to reopen the door. It should then close normally.

7. How to change the combination ?  Open the safe and locate the change button behind the cover. Press the change button and enter the new combination while the green light is on. Then press the * key to confirm and turn off the green light. Enter the new combination and press the # key to exit.

8. Why can't I open the door of my newly purchased safe even though the key can be turned?  Because new safes are manufactured with a protective mat placed on the lower left corner to protect the paint on the door. When the key is turned to the open position, hold the large key handle with your right hand and pull the mat outwards with your left hand.

Below is a more detailed classification of the issues: 1. Mechanical combination safes (without external power supply and emergency key)

1. What should I do if I have the key but no password and can't open the cabinet?

Solution: Method 1: You can obtain the initial password from the manufacturer using the serial number on the safe and the purchase invoice. Then, you can open the safe using the key and the initial password.

Method 2: Without a serial number and purchase invoice, the safe can only be opened by professional personnel through forced entry.

2. What if I have the password but no key and can't open the cabinet?

Solution: In this case, the only solution is to replace the master key lock. After replacing the lock, you can open the cabinet using the key and the combination.

3. What should I do if I can't open the cabinet without a password or key?

Solution: In this situation, the safe can only be opened by force. Both the combination lock and the master key lock need to be replaced before it can be used normally.

4. Why can't the safe be opened even though the password operation is correct?  It might be due to a shifted password. There are many reasons for this, such as the root ring not being properly positioned or the locking pin being loose. First, add or subtract one digit from the original password. Then, add one digit to the first group of the original password, subtract one digit from the second group, and add one digit to the third group. Alternatively, subtract one digit from the first group, add one digit to the second group, and subtract one digit from the third group. If it still doesn't open, please make a record and send it to after-sales service personnel for on-site service.

2. Fingerprint password safes (usually equipped with an external power supply and an emergency key)

1. What should I do if I have fingerprints but no power and can't open the cabinet?

Solution: If an external power source is available, the safe can be opened using a fingerprint sensor with batteries installed. If an emergency key is available, the safe can be opened using only the emergency key (the emergency keyhole is usually behind the brand logo on the panel). If neither an emergency key nor an external power source is available, the safe can only be opened by a professional forcibly opening it.

2. What if there are no fingerprints, but the cabinet is powered on and cannot be opened?

Solution: If you have an emergency key, you can use it to open the safe (the emergency keyhole is usually behind the brand logo on the panel). After that, you can reset your fingerprints to use it normally. If you don't have an emergency key, you can only open the safe by having a professional force it open. After that, you can reset your fingerprints to use it normally.

3. What if the cabinet can't be opened because there are no fingerprints and no power?

Solution: If you have an emergency key, you can open the safe using only the emergency key (the emergency keyhole is usually behind the brand logo on the panel), install the battery, and then reset your fingerprint before you can use it normally. If you don't have an emergency key, the safe can only be opened by a professional, and then the battery and fingerprint must be reset before you can use it normally.

3. Electronic combination safes (usually equipped with an external power supply and an emergency key)

1. I have the master key, but no password, so I can't open the cabinet. What should I do?

Solution: If an emergency key is available, the safe can be opened by using both the emergency key and the master key simultaneously (the emergency keyhole is usually...).

(Behind the brand logo on the panel); Without an emergency key, the safety mechanism can only be opened by a professional forcibly opening it.

The cabinet can only be used normally after the password is reset.

2. I have the master key and the password, but I still can't open the cabinet. What should I do?

Solution: Possibility A: In most cases, the power is dead. Even if the display still shows two bars of battery, it might still be dead, as the display isn't always accurate. Solution a: Use the master key and emergency key simultaneously to open the safe, then install new batteries to restore functionality. Solution b: Install batteries in an external power supply, plug it into the corresponding external power port on the panel, and then use the master key and combination to open the safe (the combination won't be lost during a power outage; the external power port is usually located at the bottom of the panel). Possibility B: The electronic panel is faulty. In this case, a professional needs to replace the panel and reset the combination before it can be used normally.

3. What if I have the password but no master key and can't open the cabinet?

Solution: In this case, the only solution is to replace the master key lock. After replacing the lock, you can open the cabinet using the key and the combination.

4. What should I do if I can't open the cabinet without the password or the master key?

Solution: If an emergency key is available, simply replace the master key lock, then use the new master key and the emergency key to open the safe. After resetting the password, it can be used normally. If an emergency key is unavailable, the safe can only be opened by a professional through forced entry. After replacing the master key lock, the password can be reset before it can be used normally.

5. Why can't I open the safe even though the green light is on after replacing the batteries?  There are two possibilities. First, the customer's batteries may be low on power. Solution: Replace with compatible batteries. Second, it's possible that when inserting the key, you turn it to the right before entering the combination, causing the lock clamp to jam the electromagnet and preventing the key from turning properly. Solution: Insert the large key horizontally, enter the combination, and turn the key while the green light is on to open the safe door.
