Why does the car lock automatically unlock?

[VonNaomi]

It may be that one of the four doors was not properly closed when locking the car. Below is an introduction to car door locks: Electronic door locks: These use programmable memory and data reading devices, making the keys difficult to duplicate. The key contains a dedicated electronic chip measuring 3.5×3.5mm, which stores a specific password. When the key is inserted into the lock, the password is sent to the lock's memory, generating a magnetic field and inducing voltage in the coil on the chip, which serves as the power source for unlocking. If the password in the key matches the lock, the lock opens. Mechanical door locks: A six-digit password can provide over 3.25 million combinations, offering extremely high security. The optional password groups are arranged consecutively, making it convenient to choose an easily memorable password. The currently developed basic models allow the password length and quantity to be redesigned according to user needs. An alarm interface can also be added for users.
