What to Do When the Car Door Won't Lock?

[MacVera]

If the car door won't lock, the simplest method is to use the spare mechanical key to lock it. The reasons why the car door won't lock are as follows: 1. If you're using the remote key to lock the door, it might be due to a malfunctioning remote lock or factors like aging of the car's remote transmitter antenna, which can render the remote key ineffective. In such cases, you can use the spare mechanical key to lock the door. 2. Another scenario is the presence of strong magnetic field interference around the car. Since smart keys use low-intensity radio waves, they may not function properly under magnetic interference. 3. If the car frequently fails to lock remotely in a particular location, you should be wary of a door jammer. Some criminals use a radio signal jammer that emits electromagnetic waves at the same frequency as the lock signal, thereby blocking the electronic code of the car's central locking system and temporarily disabling it.
