I have just purchased a 1997 9000 CSE. It came with 3 keys, but 0 remotes. It looks like it should have factory keyless installed, just didn't come with remotes.
I got 2 remotes off of eBay, and thought an independent mechanic with Tech II could program them, but he's telling me that I have to have at least 1 working remote to program new ones in.
I am able to arm and un-arm the alarm with the key, I just want to add keyless entry.
I know that the 9-5 requires at least 1 working transponder key to program new ones in, but is this the case with the 9000?
