I have a 1998 VT Senator 220i

I have 1 x working key and also have the tag that goes in the glove box to disable the security system.

I have a scanning tool (snap-on) to reprogram new keys and not having any luck. I have 2 new keys, coded them. They unlock and lock the car but DO NOT start the car. only my original key will start the car.

any ideas?
