When Your Lexus Smart Key Fails

Keyless Entry

Your Lexus key fob contains technology that connects to sensors in your vehicle. It lets you lock and unlock your doors and trunk, as well as unlock the trunk and turn on the ignition with a push button. This remarkable convenience makes driving in a Lexus more fun than any other vehicle. The key fob could require replacement with the battery at some point in order to work correctly.

Immobilizer System

When you put the key in the ignition, it sends an ID code to a receiver in the car. The computer will allow the engine to start if the ID code matches a previous one stored in the car. If the ID code doesn't match, an immobilizer is activated to stop the car from beginning.

This technology is not foolproof however it does work even if you lose your keys. In fact, it's possible to "hack" an anti-theft system using radio waves. A burglar could use an aerial antenna to detect the signal and then spoof it into telling the vehicle that the key is present.

Experts are working on more secure systems to circumvent this. Certain systems provide WiFi connectivity, undetectable installations and pin code entry using buttons on the dashboard. Thatcham Research has developed a system of grading and approbation to assist buyers in comparing the various products.

If you're concerned about the anti-theft feature of your car the best thing you can do is replace the battery, especially if it's old. A quick look through the owner's manual will help you find the right replacement. Fuses are another potential culprit which is why they must be checked frequently. A replacement is available at the auto parts store in case one blows.
