Replacing lost transmitters

Take all your vehicle’s transmitters

to your dealer if service is required.

If you purchase additional

transmitters (up to four may be

programmed into memory), perform

the following procedure:

To reprogram the transmitters

yourself, place the key in the

ignition and turn from OFF to ON

four times in rapid succession within

3 seconds. After doors lock/unlock, press any control on all transmitters

(up to four). When completed, turn the ignition to OFF.

All transmitters must be programmed at the same time.

SECURILOCKY PASSIVE 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.

This system provides an advanced level of vehicle theft protection. Your

vehicle’s engine can only be started with the two coded keys provided

with your vehicle. Each time you start your vehicle, the coded key is

read by the anti-theft system. If the key identification code matches the

code stored in the anti-theft system, the vehicle’s engine is allowed to

start. If the key identification code does not match the code stored in

the system or if a coded key is not detected (vehicle theft situation), the

vehicle’s engine will not operate.

If there is any anti-theft problem with your vehicle, ensure ALL coded

keys for that vehicle are brought to the dealership, to aid in

troubleshooting.

The SecuriLocky passive 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, electronic devices on the key chain that can be used to purchase

gasoline or similar items, or a second key on the same key ring as the

PATS ignition key may cause vehicle starting concern and record DTC’s

under certain conditions. If present, you need to keep these objects from

touching the PATS ignition key while starting the engine. These objects
