In essence, your BMW remote key fob transmits a low-power signal that contains an identification key that your car can read up to 5 feet away. The doors can be unlocked if your BMW detects a fob broadcasting a legitimate identification key. To increase security, the identifying key broadcast is frequently changed in a manner that is difficult to decipher without having a thorough understanding of the underlying encryption.
However, if a thief is able to approach your key close enough to be within the safe 5 feet of the signal — for instance, if you keep your fob close to your front door — they might be able to use a signal amplification device to broadcast the identification key from your fob much further than the safe 5 feet, potentially making it possible to unlock a car parked on your driveway. Comfort Access’ built-in security is helpless to stop this kind of exploitation.
Since certain manufacturers, like BMW, have started creating keys with motion-activated shutoffs, leaving a fob on the side overnight won’t pose a security threat. For fobs that block the signal, third parties also provide Faraday cases that can be left on permanently or used only for storage.
