i had a buddy here in camp lejuene do this but he didnt have a crossfire. he had a keyless ignition and entry put into his car for about 400$ i am abt to start looking into it but i dont know much about it. it still costs a bit but it dosnt cost as much as a new ignition put into it. and it came with a wireless remote to start ure car and unlock it. from what ive heared through several people from buying it and it bein put in is about 400-500$ it still costs a bit of money though.
