1997 Chrysler Sebring Won't Start Properly

I recently had the ignition switch replaced on my 1997 Chrysler Sebring Convertible (V8 with 110,000 miles). This fixed the problem of not starting at all, but now I must go through this ridiculous ritual of locking the car with the key from the outside then removing the key, reinserting the key to unlock and then trying to start it again. I typically have to do this 3-4 times before the car will start.

The vehicle came with two "keys" (?) For the Silencer Security System and I am wondering if the anti-theft system has a glitch.

Help! I'm a single mom and dealerships are telling me it's a computer issue which translates into several hundred dollars.

Thanks so much for any assistance.
