You have to program the new key for your pcm. Vehicle won't start without it. The chip is in the black plastic section of the key.

i seen autozone and others have ignitions with and with out chips so since mine has the theft light on its a chip key? so do i have to go to the dealer to program the new key since i dont have the old one?

Your 2000 has a chip in the key. The PATS system was introduced on the Explorers for the '98 model year and every one since has it.

If you do not have BOTH of the original keys, you will need to take the car and the new key to the dealer to have it programmed. You may be able to take it to a non-dealer garage IF they have the proper programming equipment.

As gijoecam said, ALL Explorers from 1998 on have the PATS system which includes an RF chip in the key.

Another thought: When you replaced the ignition cylinder, did you have the cylinder keyed to your existing keys or did you get two new keys with it? Your best (and least expensive) bet will be to pop the ignition cylinder back out, take it to a locksmith, and have it re-keyed to your old ignition key.

FYI, they do not have to both be the original keys. They simply have to be two working keys to program a third.

Quite right - I meant original as from the old lock set, not from when the car was new - should have clarified

This is the only way to do it "cost effectively"!

There is no way to program the new keys because the old keys will not turn the cylinder.
