Mini Pocket Car Remote Signal Jammer Shield supporting 315MHz, 433MHz, 868MHz, and 915MHz frequencies with a compact weight of only 0.3kg.

Car remote jamming occurs when a remote device blocks or jams the locking mechanism of a motor vehicle. When you press your vehicle's remote control, a potential thief simultaneously presses a different remote button, effectively blocking the signal transmission from your remote to your vehicle.
