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.
I have read via Google that they do, however I can personally attest that mine does not.
A key is needed to enter, lock, and unlock many Mercury Sable cars. A key is also needed to start the engine.
Mine does not, but it may depend on what options the vehicle came with.
Does a 1999 Volvo s70 have a chip in it
No it does not.
yes
If the key is gray, yes. If the key is black, no.
look in the glove box
No.. the chip "so-to-speak" is integrated into the key lock cylinder.
Before 1998 - no. 1998 and after - yes.
most likely it is your fuel pump the same thing happened to my 1999 mercuy sable
Maybe the chip in the key is defective.
