Do I have to replace the computer if I replace the ignition
I have to replace the ignition will the new one have
to be programmed to the computer?
No you won’t need to replace the computer but that security system will need to be reprogrammed to recognize the new components, a good locksmith can do this on site, so call around to find one that can. If your unfortunate and no locksmith can do it then your stuck with the dealership and most likely a tow bill to get it there.
