Abstract
A vehicle immobilizer locks the transmission shift lever in the park position. A key has an identification code and a transmitter. When the key is inserted into a key cylinder and used to rotate the key cylinder to start the vehicle, a code detector reads the key code. The key code is then compared to a prestored key code. If the key codes match, a first detection signal is generated. A brake detector detects when the brake pedal has been depressed and generates a second detection signal. When both the first and second detection signals are generated, the shift lever is unlocked and an engine ECU is enabled so that the engine may be started and the transmission may be engaged.
