SECURILOCKYPASSIVE ANTI-THEFT SYSTEM
Your vehicle is equipped with a coded-key anti-theft system. Only the
correct key will be able to start your vehicle. If your keys are lost or
stolen, you must take your vehicle to your dealership for key
reprogramming.
The SecuriLockypassive anti-theft system provides an advanced level of
vehicle theft protection. Your vehicle's engine can only be started with
the two special SecuriLockyelectronically coded keys provided with
your vehicle. Each time you start your vehicle, the SecuriLockykey is
read by the SecuriLockypassive anti-theft system. If the SecuriLocky
key identification code matches the code stored in the SecuriLocky
passive anti-theft system, the vehicle's engine is allowed to start. If the
SecuriLockykey identification code does not match the code stored in
the system or if a SecuriLockykey is not detected (vehicle theft
situation), the vehicle's engine will not operate.
The SecuriLockypassive anti-theft system is not compatible with
aftermarket remote start systems. Use of these systems may result in
vehicle starting problems and a loss of security protection. Large metallic
objects or devices such as the Mobil Speedpassyon the same key ring
as your SecuriLockykey may cause vehicle starting problems. These
