Handheld Cell Phone Blocker 16 Bands 5G Jammer

Signal blocker Jamming Meaning

The reason why the jamming device can make the electronic car key malfunction is mainly to use the electromagnetic wave of the same frequency or similar frequency that it emits to interfere. "Fortunately, this kind of interference can generally only cause the operation to be invalid, and no other operations will be performed, so the car owner does not need to worry too much.

This kind of interference is caused by the superposition of electromagnetic waves from different emission sources. The signal jammer causes the signal to be disordered, so that the receiving device cannot identify the useful signal and cannot follow the command of the remote control. However, since the interference does not know the meaning of the signal, the transmitted signal cannot "issue an effective command" to the car.
