Battery went dead, jumped to start, now radio won't play, word CODE came up in little screen above radio, Help

Normally put radio code in by holding the buttons as the numbers come up

Charge it, or hook up jumper cables, wait a few minutes before you actually try to start it. Make the ground to the running engine the last connection you make.

You could have blown the main fuse while doing the jump start. Also check the fusible link on the power battery cable.

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

The voltmeter should only go as high as 14-15 volts when the engine is running. I would check for a poor connection between the battery and starter.

Your radio is in theft lockout, you need the security code that came with the owners paperwork new.

Sounds like the battery is completely dead. It's either a faulty battery(go and have it checked) or a dead alternator. To check if the alternator is bad, once the car is started, remove the negative battery cable, if it stays on, then the alternator is good, if it dies immediately, then the alternator is bad and needs replacement.

did they run a test on the alternator!! at battery when off should be at least 12.6 volts, less than 12 volts battery is bad. when running at battery voltage should be at least 14.1 to 14.7, thats if alternator is ok. if less than above replace alternator. if alt. is ok, could be a bad battery.

TEST YOUR ALTERNATOR AND HAVE THE BATTERY CHECKED IF THEY ARE OK
YOU MAY HAVE ELECTRICAL SHORT

You can recover the code at the following site without pulling the radio. The site will show you how to get the 8 digit serial number of the radio from the radio and then use that serial number to find your code. Takes about ten minutes. Look at the notes if you have trouble
