how to remove transmitter from audiovox?

Hello all, I was successful in programming an old transmitter to use on the new alarm (APS901) remote starter. However, it seems now the same transmitter will remote start two vehicles at the same time (old car, new car when they are together.) Is there a away to remove the transmitter from the old car completely? I followed the instructions below. Thanks. To program this transmitter into your remote start upgrade unit: 1) Turn the ignition to the on position 2) Press and release the programming switch 3 times 3) Press and hold, for 3 seconds, the button of the transmitter you wish to add until the parking light flashes indicating the transmitter has been learned. 4) Repeat step 3 for each transmitter up to a total of 4. Turn the ignition off to exit the program mode

Learning the remote 4 times in a row will delete any old codes. Follow the above instructions 3 more times and you should be good...Mike M2
