Electronic combination safes are considered by many to be a high-tech product that has emerged in recent years. While they are generally perceived as more difficult to open, they are actually much easier to open than mechanical combination locks. Their biggest weakness lies in their limitations. They cannot be opened without power, and they are prone to wire breakage, circuit board burnout, and display screen malfunction, rendering them unusable in several situations. Therefore, an emergency keyhole is essential. In the event of a power outage, a burnt-out circuit board, or a malfunctioning display screen, the safe must be opened using an emergency key through this keyhole. This greatly facilitates locksmiths in opening electronic combination locks.
To open the safe, follow the normal procedure. With power on and knowing the password, first press the "#" key. After the display light illuminates, enter the previously set password on the numeric keypad. Press the "#" key again, then insert the key. Turn the key, then turn the handle; the safe door should open.
The editor from Henan Huadu Times Furniture explains the five methods for opening electronic combination lock safes as follows:
The first technical method is to find the emergency keyhole if the customer forgets the password and loses the emergency key. The emergency keyhole is usually covered by a cover. Open the cover to find the emergency keyhole. (Emergency keys are mostly for Phillips head locks.)
Then, using a lock-picking tool, open the emergency lock, and then open the main key lock by turning the handle. This will open the safe door.
The second technical method, without lock-picking tools, involves using a screwdriver. Align the screwdriver with the lock cylinder and strike it with a hammer to push the cylinder out. This will create a hole. Insert a '7'-shaped hook and press down the stop valve inside. Then turn the key and the handle; the safe door should open. Afterward, replace the lock with a new one. (Plum-leaf locks are inexpensive, costing only a few yuan wholesale.)
The third technical method is called the forced relay method. The method involves opening the emergency keyhole cover (which has a hole) in a safe that cannot be opened from there. A steel wire, shaped like a hook, is inserted through this hole.
Pull out the wires inside; one is red and the other is blue. Strip the ends of both wires, then connect the batteries. Connect one to the negative terminal and the other to the positive terminal to force the relay. Then turn the key and the handle to open the safe.
The fourth technical method is called the vibration relay method. This method is only suitable for small safes. Lift one corner of the safe and give it a forceful downward shake (the key must be inserted first). At the instant of the vibration, turn the key, and the safe door will open. If it doesn't work the first time, try a few more times. If the safe is larger, you will need two to three people to help. Another method involves vibrating the stop valve at the instant of the vibration, causing it to suddenly contract downwards, which allows you to turn the key.
The fifth technical method is called the "click method." Most modern electronic safes have two holes on the back for installing expansion screws to secure them to the wall, making them difficult to move. However, 98% of customers don't actually wall-mount their safes (for future relocation). You can use a flashlight (preferably a high-powered one) to shine through one hole and a 6mm wire through the other. Use this wire to click the reset key on the back of the safe door. If you click correctly, the indicator light on the outside will immediately illuminate, allowing you to reset the password using the number keys (e.g., 123). Then press the "#" key to confirm. Press the "#" key again, then the newly reset password (123), and press "#" again to confirm. Turn the key and then the handle; the safe door will open. (An emergency battery compartment can be inserted if the safe is out of power.)
