This is due to the anti-theft in the radio. Open the fuse box under the hood, pull two fuses; radio and radio back-up, put the 2 fuses back in. Turn the radio ON, it should ask for your code. Pull out the ash tray and see if you have the 5 digit code there. Enter the code and the radio should now work.

If you never entered a lockout code for your radio, youll have to take it to the dealer to get them to clear it out.

This is the anti-theft device on your factory radio. When the battery died, the radio thought it had been removed from your car and went into anti-theft mode. When you turned the car back on, the radio should have read "CODE" on the display, at which point you need to enter the factory anti-theft code. After 3 failed attempts at entering the code, it will simply read "OFF" and the radio is locked.

At this point:
- find your factory anti-theft code - it should be in your owner's manual, or you can contact a dealer to retrieve it
- turn the key to the ACC position (radio and accessories on, but engine is off)
- turn on the radio so the display reads "OFF"
- let the car sit for 1 hour
- radio will turn off automatically and reset
- turn the radio on again, and it should read "CODE"
- enter the factory anti-theft code

Make sure you have the code before starting the procedure. To enter the code, use the radio preset buttons. For example, if your code is "4321", hit Preset #1 button four times, Preset #2 three times, Preset #3 two times, and Preset #4 one time. Then hit the "Tape" or "CD" button. Radio should now be unlocked.

If its a factory installed radio and not an aftermarket radio, only dealerships can reset the radio for you. The reason for being is dealerships needs to be sure that his or her radios are not stolen.

have you vin number ready. the dealer always have factory code number

Factory radio codes are an anti-theft deterrent, they are unique to each radio and car serial number, in order to get the code the dealer will have to access the manufacturers data base, you will need to pull the radio and record the radio model number and the serial number of the chassis of the radio and take it to the dealer, they will not in most cases give the info out over the phone, this would defeat the whole purpose of the code.
