Mine does not, but it may depend on what options the vehicle came with.
To disable the factory alarm on a 2000 Mercury Villager, put the key in the ignition and turn it halfway. Let it stay in the spot for 10 minutes and start the car.
I have read via Google that they do, however I can personally attest that mine does not.
30- 32 psi engine running, 36-40 psi key on engine off.
Turn the key to the right.
Go to a Ford dealer.
Most 2000 Concordes do have chip keys.
If it has a cover on the key, yes. If it is a steel key no.
no, its not a laser key either
Maybe the chip in the key is defective.
In 1999 it may or may not have one. If it has a thick black head with the hole in the head of the key being offset, then it is probably a chip key. If the hole is in the center top of the key or completely metal then it is not a chip key.
Amazingkeys.com has the 2000 Buick LeSabre Key. It does have the chip in it.
