Yes, it is part of a very complicated & VERY TROUBLESOME system known as passlock. If you Google this system you will find it's a typical problem on this model,but, you can also find enough info there to diagnose & repair yourself.
Yes
I don't think you can bypass them.
You can't bypass or reset security system, bring it to the dealer.
No, a 1991 Chrysler New Yorker does not have chip key.
Yes, it has a chip. You can take the key to the Walmart auto section where they make keys. They can test it and tell you if it for sure has a chip but I am 99% sure it does.
if it is a gm with the little resistor chip in it you could try to cleand the chip with alcohol to remove oils from skin and such
according to my gm dealer it does not. The passlock system is in the ignition cylinder
yes
I don't think you can bypass them.
is the 93 olds is the as a 95 olds on the security light
The key has a built in Chip and can only be purchased from a Olds. dealer cost is around $21. edit The ignition actually uses PKII (pk2)system. There is not a resistor in the key. The chip is on the key lock cylinder not the key. Dealer is still the best place to get them. Last one I got was 9 dollars.
you can copy any key, but, if the key has a "chip" in it you will have to take it to the dealer to get a copy made. I drive a 2004 F-150 and it has a chip in it.
YES
No it does not if it is a s10 blazer
No. So you can easily get a copy of it.
Yes every F-150 since 1999 has a transponder "chip" in the key. You can get replacements or extras from a locksmith or your local dealer.
