The 2003 Mitsubishi Eclipse’s "Anti-theft engine immobilizer with security keys" is designed to significantly reduce the possibility of car theft. The system immobilizes the vehicle if an invalid start is attempted. A valid start can only be accomplished (subject to certain conditions) by using a special transponder key "registered" to the ignition switch lock.
