dball2pro, 2007 pontiac g5

I am working on a 2007 Pontiac G5 it has a manual transmission. and customer wants to use there factory key fob to start....I can not find any information on how to put in ready mode for exiting the car? as if I don't do that it will not try to start?

Im not sure if you even can but if its possible I would say that you would do the exact same procedure as with an aftermarket remote except instead of pressing the start button on the remote after setting the brake I would assume its you hit the lock button 3 times on the factory remote. But I haven't done a manual without an antenna/remote package on a dball 2 yetdouble-secret reverse-osmosis speaker-cone-induced high-level interference distortion, Its a killer
