Why does the Wuling Hongguang S beep three times but fail to lock?

[VonHaven]

Wuling Hongguang S beeping three times but failing to lock may be due to the main control lock hook falling off. Here are some relevant introductions about car door locks: 1. Electronic door lock: Refers to the use of programmable memory and data reading devices, making the key difficult to replicate. The key contains a 3.5×3.5mm dedicated electronic chip with a specific password. When the key is inserted into the lock hole, the password is sent to the memory in the lock, generating a magnetic field and inducing voltage in the coil on the chip, which serves as the unlocking power source. If the password in the key matches that of the lock, the lock opens. 2. Mechanical door lock: A six-digit password can have over 3.25 million password combinations for the owner to change at will, providing extremely high security. Optional password groups are arranged consecutively, offering convenience for selecting easily memorable passwords. Currently developed basic models can have the number of password digits and combinations redesigned according to user needs.
