The car is like our mobile home. Sometimes many car owners habitually put a lot of valuables in the car, but they don't know that it is easy to steal. One of the factors is that the door can not be locked. Why can the door lock not be locked? What are the reasons for the door not being locked? Let's discuss it next
Reasons for door lock failure:
1. If the remote key is used to lock the door, it is likely that the remote lock fails or the antenna of the remote transmitter on the vehicle is aging, which may cause the remote key not to work. In this case, the spare mechanical key can be used for locking.
2. There is also a case that there is strong magnetic field signal interference around the car. Because the smart key uses low-intensity radio waves, it can not work normally in the case of magnetic field interference.
3. If your car often fails to lock by remote control in a certain place, car owners need to pay attention to door jammers, because some criminals use a kind of radio signal shielding device, which can transmit electromagnetic waves with the same frequency as the lock signal, thus shielding the electronic code of the car lock, making it temporarily out of order.
If it is found that the door can not be locked, the simple way is to lock it with a spare mechanical key. Generally speaking, there is a mechanical key hidden in the remote key. Car owners should form the habit of pulling the door with their hands after locking the door, and check whether each door has been locked.
