My car won't start

Ok, those systems might still work because the not require as much energy as the starter. Check the Battery Voltage with a good Voltmeter. If below 12, there might be your problem!

check the ground leg to your engine.. it runs off the neg. battery terminal. will connect to frame and engine.. pull it off, wire brush it put it back.. you radio will work, 'cause it draws much less current, and is grounded in dash.

Those are all really common symptoms of the alternator going bad on those cars. I would have it checked to make sure it's charging properly.

sounds like the rke module (Remote Keyless Entry) module losing power, I hope that helps you out

have battery tested if good fully charge,then check all relays and fuses.

any real answer yet? did the problem ever get resolved? i have the same problem with my sister's car. too cold to diagnose tonight, but will post the solution probably tomorrow. since the lights and heater works, but ignition and radio arent getting power, my first guess is there's probably a fried fusible link which controls the 2nd accessory power to the ignition switch. will post a solution soon.

It is in Theft lock from the loss of power. Contact your local dealer for help getting it unlocked.

Could be the security system or the neutral safety switch.

battery dead.

I found a paritally blown fuse. When the fuse blew metal pieces ended up partially making contact. After replacing the fuse everything worked great.
