Certain vehicles must have the security code set that you can obtain from the owner's manual for your vehicle or online.

Transponder chip

The transponder is a microchip with a unique code. When it is inserted into the ignition, the transponder chip sends a radio signal to the immobilizer system of the vehicle. The computer in the car then decodes the signal and determines whether or not it is a valid key. If the signal doesn't match, the car's computer will shut off the ignition and stop it from beginning. This makes it more difficult for thieves to rob a vehicle.

Modern cars are often equipped with this security device. But, as with any electronic device, the transponder chip can occasionally malfunction or fail. This can be frustrating and cause your car will not start. There are a few easy solutions you can use to fix the problem.
