Skeptics often ask questions of the system, the most common regarding the repercussions if the batteries in the key-fob go dead.

The answer?

Within the transceiver key is hidden an old fashioned metal key with teeth on it. This is used in emergencies to unlock the car and start the engine the old fashioned way. Most vehicles can also alert the driver via a warning in the instrument cluster if the battery is on its way out.


Losing the transceiver key has the same consequences as losing a standard key-- though most models actually prevent the locking of their transceiver key within. Since the car knows whether or not the key is inside, it can sound a special alarm when the driver tries to lock themselves out.

You shouldn't leave a running car unattended, but the intelligent key system has a benefit over a standard key if you do. The transceiver key is required to start the car, but it can leave the vehicle while it's running. If your ride were stolen while running without its key on board, thieves would be unable to re-start it after turning it off or running out of gas.

Intelligent key systems are becoming more and more popular for their convenience and high-tech attributes. As the technology becomes more accepted and less expensive, chances are increasingly likely that it will be available on your next ride.
