info on keyless remote?

[chmercer]

ok so i have a y33 and a s14. my original s14 keyless remote broke, so i reprogrammed it to one of my extra y33 remotes. now the remotes operate both cars at once since they are both in the driveway so its kindof retarded. how can i fix this? i dont have a good enough understanding of how the remote functions to figure out how to program them properly to avoid this happening again.

would it work if i like drove one of the cars out of range, then reprogrammed the other car, then repeat with the other car on a seperate remote? do i need to have the 2nd remote out of range when i reprogram the first remote?
