Sorry, the 2 dr Sebring is actually a Mitsubishi and cannot add keys without a programming tool.
Go to your Chrysler dealer and ask them to program it.
The dealer ship scan tool is required.
Yes. If you have a grey key, it has a transponder that electrically reads a chip in the key. You essentially have two locks -- one mechanical and one electrical. They both have to work to start the car. Should you go and have a generic key cut that fits the ignition, even thought the mechanical lock cylinder will turn -- the transponder won't allow the engine to fire. Any quality locksmith can program the car's transponder to match the electronic code of the key.

If you have chip keys, the dealer will need to program the keys to the new PCM.
It will depend on the dealer. Some will be as low as $40, or as high as $200.
What state was it purchased in? In different states the programming process is different due regulations for that state.
