SECURILOCK PASSIVE ANTI-THEFT SYSTEM
SecuriLock passive anti-theft system is an engine immobilization
system. This system is designed to help prevent the engine from being
started unless a coded key programmed to your vehicle is used. The
use of the wrong type of coded key may lead to a "no-start" condition.
Your vehicle comes with two coded keys; additional coded keys may be
purchased from your dealer. The dealer can program your spare keys to
your vehicle or you can program the keys yourself. Refer to
Programming spare keys for instructions on how to program the coded
key.
