Cadillac Repair: ignition, volt ohm meter, cadillac deville

Question
I have a '90 cadillac deville that i just installed a new ignition in. The key won't even turn over. I've tried moving the wheel side to side and making sure the care is in park all the way. If I bypass the VATS will the key turn? I don't know if the VATS prevents the key from turning or just the vehicle from starting.

Answer
If I bypass the VATS will the key turn?  NO.

I do not have a website so you will have to e-mail: onlineautohelp@msn.com in order to obtain the information necessary to fix your vehicle.
