Remote Keyless Entry System Operation You can lock and unlock your doors from about 3 feet (1 m) up to 100 feet (30 m) away using the remote keyless entry transmitter supplied with your vehicle. Q (Lock): Press this button once to lock all of the doors. Pressing lock again within three seconds may cause the horn to chirp for lock confirmation. You can choose different feedback options for each press of the lock button. See "Lock Feedback" and "Unlock Feedback" under DIC Vehicle Customization on page 3-63 for more information. K (Unlock): Press this button once to unlock the driver's door. The interior lamps will come on. Pressing unlock again within three seconds will cause the remaining doors to unlock. L (Panic): Press this button to sound the horn and flash the headlamps and taillamps for up to 30 seconds. Panic can be turned off by pressing the button again, by waiting for 30 seconds, or by starting the vehicle. Matching Transmitter(s) to Your Vehicle Each remote keyless entry transmitter is coded to prevent another transmitter from unlocking your vehicle. If a transmitter is lost or stolen, a replacement can be purchased through your dealer. Remember to bring any remaining transmitters with you when you go to your dealer. When the dealer matches the replacement transmitter to your vehicle, any remaining transmitters must also be matched. Once your dealer has coded the new transmitter, the lost transmitter will not unlock your vehicle. Each vehicle can have a maximum of four transmitters matched to it. You can choose different feedback options for each press of the unlock button. See "Lock Feedback" and "Unlock Feedback" under DIC Vehicle Customization on page 3-63 for more information. 2-6
