What Causes a Smart Car Key to Fail to Lock the Doors?

[OValerie]

There are several reasons why a smart car key may fail to lock the doors: Remote Lock Malfunction: If you are using the remote key to lock the doors, it is likely that the remote lock is malfunctioning or the antenna of the car's remote transmitter has aged, causing the remote key to fail. In this case, you can use the spare mechanical key to lock the doors. Strong Magnetic Signal Interference Around the Car: Another possibility is that there is strong magnetic signal interference around the car. Since smart keys use low-intensity radio waves, they may not function properly under magnetic interference. Radio Signal Jammers: If you frequently encounter issues with remote locking in a particular location, the car owner should be wary of door jammers. Some criminals use radio signal jammers that emit electromagnetic waves at the same frequency as the lock signal, thereby blocking the electronic code of the car's central locking system and causing it to temporarily malfunction.
