The pulsar allows you to have upto 4 keyless remotes programmed to your car, by programming the 5th remote you lose the first one etc.
Get into your car, close all doors and leave doors unlocked.
Insert your key and turn to ACC then back to off position (no need to press the button to eject key)
This needs to be done in quick succession and on the 5th turn to ACC your hazard lights will flash once indicating you're in programming mode.
Press button on your remote then doors will lock.
Repeat if you have multiple remotes.
