Because that's exactly what it's supposed to do!.. The 'reason' it's doing that is : the security system does not recognize this new/strange key you have now and thinks someone is attempting to steal the vehicle .. You need to take the old original key and this new key, that came with the column, to a locksmith so a key can be made that will work.. Probably be a good idea to have at least 1 spare key made as well... It ain't going to start and keep running until that's done! ..... This is not something that can be done by simply reprogramming the system to accept that key.

But I changed everything. The Whole Steering Column. Wires and all..

That doesn't matter.. The *original key itself* has a 'chip' inside the black part of the key and the system is programed to accept that chip only.. Locksmith can read the chip from the original key .. Then cut a new key that has the same chip in it .. that will work in this new switch.. Sorry, but that is the only way this is going to work and the most logical way to get it running!
