Keyless Entry

Your Lexus key fob is armed with hardware that communicates with sensors in your vehicle to lock and unlock doors, open your trunk, and then turn on the engine. This is an amazing convenience that makes driving a Lexus significantly more enjoyable than driving a traditional car. The key fob will eventually need a battery replacement in order to work properly.

Immobilizer System

When you insert the key into ignition, it transmits an identification code to the receiver in the car. The computer will allow the engine to start if the ID code matches an earlier one stored in the car. But if the ID code does not match, it activates an immobilizer, which stops the engine from running.

This technology can be used even if your keys are stolen but it’s not foolproof. It is possible to “hack”, or manipulate the anti-theft radio wave system. A thief can use an aerial antenna, and then spoof the signal to tell the car the key is in the ignition.

Key Blade
