BS there IS a procedure other than take it to the dealer..
Ron is correct. It involves adjusting the pressure at each tire in the proper sequence such that it can 'see' what sensor is at the location its expecting. The trick is to do it in the time allotted.. My dad even did his.. If he can do it anyone can.. I think it helped him to have the valve stem caps removed and a open air chuck to push on the stem.

1 Turn on your Saturn ignition switch.
2 Press the "Lock" and "Unlock" buttons simultaneously on your lock remote. Keep holding the buttons down until you hear the horn beep. This takes about five seconds.
3 Deflate or inflate air into the driver's front-side tire for eight seconds. Listen for the horn to beep one time. When you hear the horn beep, it is an indicator that the tire is at the right pressure level.
4 Repeat the previous step for the remaining three tires. The remaining tires must be checked in the following exact order, the passenger-side front tire, the passenger-side rear tire and the driver-side rear tire.
5 Listen for your horn to beep twice. When the horn beeps twice, it is an indicator that your tire pressure in all four tires is at the recommended level.
6 Turn the ignition switch off. When you turn the ignition back on, the tire pressure light is reset.
