I recently mentioned how many new cars use a very convenient keyless entry system, and how wrapping these keyless devices in tin foil or placing them in a metal container can stop criminals from stealing the vehicle.

Unfortunately, many of them have forgotten that they did this when they used the microwave the next morning.
They only made this mistake once.
