I removed the battery and now the car won't start

'I disconnected the car battery/changed the car battery and now my car won't start'

Another common question on Fixya.
You've done nothing wrong. It's simply that the immobiliser doesn't recognise the key.

Put the key into the ignition. Turn the ignition on. Press the LOCK button twice on your remote. Wait 1 minute.

Turn the ignition off and press the UNLOCK button on the remote a couple of times. This will disarm the immobiliser.

The key should be recognised and your vehicle will start.

1995 geo tracker won't start. I've replaced everything except the ignition switch. It used to click when i turn the key, now it won't even click.


DISCONNECT YOUR BATTERY AND RECONNECT, THIS SHOULD RESET THE BRAIN.

ALSO...WHEN YOU TURN THE KEY, LISTEN TO HEAR IF YOU CAN HEAR THE FUEL PUMP COME ON...IF NOT, GUESS WHAT? HOPEFULLY NOT!... BUT,YOU MAY NEED TO REPLACE THE FUEL PUMP, IF YOU CAN'T HEAR IT WHEN YOU TURN THE KEY, AFTER YOU'VE RESET THE BATTERY!

HOPE THIS HELPS!
