I got a spare original key with no battery in it put new battery in and it work fine to open the doors. But when i try to start the engine it fires up but then die.
Saw this tips in this tread:
"Insert the key into the ignition switch.
Press either the lock or unlock button momentarily twice.
Turn the key in the ignition switch to the ON/RUN position within 30 seconds. "

Try that but the car did not start at all now an the key is now totaly dead do not even work to open the doors that it use to.

What to do?
