2001 Yukon XL Keyless entry receiver position

[foob]

I have purchased a 2001 Yukon XL that has keyless entry system on it but has no transmitters. I understand in order to buy the right transmitters I need to get a number off of the receiver. Does anyone know where the receiver is located on the car? , and what should I look for ?

Any help is greatly appreciated.

I just got a transmitter off Ebay for my 2001 Yukon XL. You need to look for the following information when getting one (it will be located on the back of the transmitter):

GM/Lear 15042968
FCC ID: KOBLEAR1XT
CANADA: 3521 102 1718

After you get your new transmitter(s), here is how you program them:

Start with the ignition OFF, hold down the power unlock button on the door panel.
Turn ignition key ON, OFF, ON, OFF. Release power unlock button on the door panel. The locks will cycle once.
Hold down the keyless entry transmitter LOCK and UNLOCK buttons for 15 seconds. The locks will again cycle once.
Repeat step #2 for each additional keyless entry transmitter.
You can program up to 4 transmitters per vehicle.
Turn the ignition on to exit the keyless entry transmitter programming mode. Programming is now complete.

Good Luck
