Transponder Keys - have a chip inside the handle of the key, which also often features remote control buttons for locks & trunk access. "Remote keys" and "switchblade keys" are two types of transponder keys.Smart Keys/ FOBIK Keys - an all-in-one car remote & key, usually standard with push-button start & "keyless entry" carsVATS Keys - for older model GM vehicles have been called "chip keys" because of the resistor on the key blade. The resistor looks like a "chip," but in fact is not a computer chip at all.
Most 2000 Concordes do have chip keys.
The dealership (if it is one of those keys which require a coded chip reprogram).

Not all models have chip. Engine immobilizer is a part of security and was optional.
i have a 85 z turbo and it dose not have a chip just had 2 keys made
Unfortunately, you'll have to go to the dealership, and the keys can run $30. There is a security chip in the key, and it has to be matched to the car. Most key copy stores will have a blank that looks very similar, but it doesn't have a chip in it.
If you had keys with computer chip embedded,you will have to go back to a dealer,and have it checked&ordered..
