Escalade 2000 Keyless Remote Programming
Be careful when reprogramming your receiver. Some guides talk about connecting two points on your DLC. If the guide applies to your car and you are sure about the terminal numbers then it is fine, else you could fry the 'puter. Fortunately, the 2000 Escalade doesnt need you to mess with it.

1. Turn the ignition to RUN, then to OFF. This will disarm the theft-deterrent system.

2. Remove fuse 17 (radio fuse) in the main fuse block, it is located on the left side of your main instrument panel. When the fuse block is open, the radio fuse is located on the lower right corner of your instrument panel. The fuse numbers are written beside the fuses.

3. Turn the ignition from OFF to RUN three times quickly (within five seconds). The vehicle will respond by locking the doors, unlocking the driver’s door and releasing the tailgate or panel doors. Your transmitter is now ready to match the vehicle.

4. Press and hold the LOCK and UNLOCK buttons on the first transmitter for 15 seconds. The vehicle will respond as in Step 3.

5. Repeat Step 4 for the remaining transmitters.

6. When you have finished matching all of your transmitters, replace fuse 17.

7. Check that all transmitters work by pressing their buttons.

Wish you Luck!

TIP: If after replacing a battery, your remote does not work, it might need resynchronizing

Resynchronization
Resynchronization may be necessary due to the security method used by this system. The transmitter does not send the same signal twice to the receiver. The receiver will not respond to a signal it has been sent previously. This prevents anyone from recording and playing back the signal from the transmitter. To resynchronize your transmitter, stand close to your vehicle and simultaneously press and hold the LOCK and UNLOCK buttons on the transmitter for at least eight seconds. The door locks should cycle and the parking lamps and headlamps should flash to confirm synchronization. If this does not happen, you may need to replace the battery in your transmitter or match the transmitter to your vehicle. If the locks still do not cycle, see your dealer for service.
