GMC Repair: Keyless entry system, keyless entry system, gmc yukon

Question
I just bought a 2004 GMC Yukon SLT with a keyless entry system. My problem is when I press the unlock button twice to unlock all doors, the horn blows twice. I don't want to alert the whole neighborhood every time the family gets in the car. What can I do to get the horn to stop blowing when I use the unlock button on the keyless entry system? Thanks
