Its an auto and when I twist the key the car won't turn on at all and the car is in park a mechanic said it could be an electrical issue or the starter

[717Stunna]

Took it to Chevy they said the key lost its memory to the car

yea...i dodnt think that either....huh? I didnt know there was a tx in there? What for?

Yeah they said Dont keep you key in the same pocket as your phone sometimes the two signals cancel each other out which unpairs your key to your car

Good to know. Glad it was something somewhat simple.

Since this is NOT a push button start car. Why is the FOB tied to the car? So i couldnt cut off the "key" from the FOB and use it to start car?

Im confused why a twist key car has a paired FOB. grrrrr

Theft prevention. To quote Wikipedia:

"Transponder keys may also be called “chip keys”. Transponder keys are automotive ignition keys with signal-emitting circuits built inside.
When the key is turned in the ignition cylinder, the car's computer transmits a radio signal to the transponder circuit. The circuit has no battery; it is energized by the radio signal itself. The circuit typically has a computer chip that is programmed to respond by sending a coded signal back to the car's computer. If the circuit does not respond or if the code is incorrect, the engine will not start. Many cars immobilize if the wrong key is used by intruders. Chip Keys successfully protect cars from theft in two ways: forcing the ignition cylinder won't start the car, and the keys are difficult to duplicate. This is why chip keys are popular in modern cars and help decrease car theft.
Many people who have transponder keys, such as those which are part of Ford Motor Company's SecuriLock system, are not aware of the fact because the circuit is hidden inside the plastic head of the key. On the other hand, General Motors produced what are known as VATS keys (Vehicle Anti-Theft System) during the 1990s, which are often erroneously believed to be transponders but actually use a simple resistor, which is visible in the blade of the key. If the electrical resistance of the resistor is wrong, or the key is a normal key without a resistor, the circuit of the car's electrical system will not allow the engine to get started."

They're also expensive to replace- so don't lose your spare!

Do a google search for GM VATS reprogram. There is a procedure that takes about 30 minutes I've seen for when you only have one key.

I always thought the VIN would give them the info to track which frequency your car was programmed with.
