hey guys im sure the cmaaro uses a id46 transdonder chip

its the same chip as i use on the 2008 to 2012 gholden comodore which is the same as a pontiac G8

with the commodore u need 2 keys to finish the key programming cycle
and most fo the time the custoemr only has one key so if i need to rest imobiliser or flash the bcm
i need to buy a second key then program it


is there a transponder chip that i can reprogram over and over that will suit these cars
like a battery powered one that i can program in one car and then me keep the transpoder for next job
and use it again

rather than programming chips then throwing them away cause once they are programmed they cant be programmed to another car

thanks
