Your 2001 Ford Explorer uses a key that has chip in it called a transponder (as you know). This chip has a mathematical formula that is used to answer a numeric question that your car generates. If the answer is correct the car's computer allows you to start the car. (A Simple Example: what is 5 multiplied by X?) The transponder and car both know that X = 2 so the chip responds with the answer 20, and the car, knowing the answer is correct, starts. This all happens in about a tenth of a second. There is also about a billion possible answers to the cars question, so if you use the wrong key, it will give the wrong answer, and the car will not start. So, to answer your question: If the key turns in the door and the ignition that it is working mechanically, but the transponder part is broken. If the key does not turn in the lock, the mechanical part of the key (the cuts on the key or the wafers in the lock) are not working properly. Either way, a Locksmith in your area should be able to help you out.
Probably the security passlock system (chip in key system). Check for the security light on the dash. If it is you have to go to the dealer get it repaired & reprogramed, approx $600.00. Dealer specific computer needed.
Its 1 of two things. Bad chip in key, or its the antenna that goes in a circle around the key hole to read the chip in the key. It will get worse and worse until one day it will never start again.
yes
Does a 1999 Volvo s70 have a chip in it
yes
yes
that normally means the chip in your key has to be programed or the chip has stop working so u might need a new chip
On a 1995 Ford Explorer : No ( at least my 1995 Ford Explorer XLT doesn't )
only thing i can think of is because the key has a computer chip in it if u have the wrong key or the chip is messed up the car wont start
without it the security lite will start blinking fast and the motor will only spin over but not crank
1998 Explorer uses a PATS II system with a transponder in the keyhead.
No it does not.
