Thieves use signal boosters to steal keyless cars quickly by amplifying fob signals from inside homes.

Car thieves are increasingly using signal amplification devices to steal keyless vehicles in minutes by boosting the signal from a key fob inside a home, allowing them to unlock and start the car remotely. Experts recommend storing key fobs in Faraday bags or metal containers to block signals, avoiding placing them near exterior doors, and using physical locks or steering wheel locks as added security.
