Girlfriend's car would not start.
Ran fine when parked. Next morning it would crank but would not start.
Here's what happened:
Parked the car the day before, used the key to open the trunk and the plastic key handle detached from the metal portion of the key leaving the key in the trunk lock. No big deal - just pulled the key out of the lock and snapped the plastic head back onto the metal part of the key and carried on. Problem solved,... so I thought.
Turns out the RFID chip had fallen out of the key when it came apart and I didn't notice. When I put the key back together the chip was lying on the ground (gravel driveway and the chip was encased in black plastic - about the size of the gravel, some of which is black )
The next morning that same key would operate the starter but because the chip was on the ground behind the car, the **** thing wouldn't start. Took me about 20 minutes to figure out what had happened and another 10 the find the **** black plastic chip in the gravel behind the car. At least the weather was nice !
Found the chip, pulled the key apart again, put the chip back in the key, snapped the plastic back together - key starts the car again.
That's just TOO MUCH technology !!
