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
most likely it is your fuel pump the same thing happened to my 1999 mercuy sable
No.. the chip "so-to-speak" is integrated into the key lock cylinder.
Before 1998 - no. 1998 and after - yes.
Maybe the chip in the key is defective.
