Household invisible remote control locks are specially designed for home security. They are installed indoors without exposed lock holes and without keys. The door can be opened by the remote control, making it impossible for thieves to start. The original mechanical lock does not need to be disassembled, and it is used with the remote control lock. Even if the thief opens the mechanical lock, the remote control lock inside the door cannot be opened, making your home safer. Using the American microchip rolling digital encryption technology, the password can be changed at any time and will not be cracked or copied. The lock body adopts an integrated design of zinc alloy, which can withstand the impact force of 900 kg, and it cannot be moved a little. Press the emergency switch indoors, and the lock will be opened, so that the lock can be unlocked in an emergency in case of fire and other disasters.
