My 99 gmc sierra 4wd stereo is locked and the dealer is gonna charge me to fix it. How can I get the code?


sorry there is no quick fix, if there was a general code it would be too simple to steal any radio, check the owners manual or somewhere in the glove box

Stereo locked up. So now I am trying to find the


the stereo locked up due to the anti-theft system on your car, you must of disconnected the battery and then reconnected it (power interuption) you should have a reset switch, or button, if not you will have to contact the dealer and get the lock out code. I hope this was helpful

2004 Honda Accord touch screen will not accept code numbers


DOES SYSTEM INTAKE CODE YOU TYPE AND RETURN WITH ERROR MESSAGE OR JUST PLAIN HAS LOCKED SCREEN? SYSTEM IS DESIGNED SO THAT IF INCORRECT CODE IS INPUT MORE THAN THREE TIMES SYTEM LOCKS ITSELF.WHICH REQUIRES THAN THE NAVI UNIT BE UNPLUGGED FROM BATTERY POWER FOR ABOUT 5-10 MINS TO RESET ITSELF.NOW INCORRECT CODE CAN BE DUE TO WRONG CODE/SERIAL # CARD FOR VEHICLE, UNIT HAS BEEN REPLACED IN PAST POSSIBLY AND YOU ARE INPUTING CODE FROM OLD UNIT UNKNOWINGLY. YOU ALSO WANT TO MAKE SURE CODE YOU ARE TRYING TO INPUT IS FOR NAVI-SYSTEM AND NOT THE RADIO CODE FOR THE STEREO. IF ALL ABOVE CHECKS OK THEN NEXT STEP WOULD BE TO REMOVE UNIT TO RETRIEVE SERIAL NUMBER FROM BACK OF NAVI UNIT THEN GO TO NEAREST DEALARSHIP WHO CAN THAN RUN S/N THROUGH HONDA IN SYSTEM AND RETRIEVE CORRECT CODE FOR THAN SERIAL NUMBER. LET ME KNOW HOW IT GO'S

I have a 2004 chevy trailblazer i need the stereo code its locked


I had this problem myself. You can get the code by simply giving the dealership a call and giving them the stereo serial number. Many dealerships put these on a sticker on the glove box somewhere. Or you may have to get it from the bottom of the stereo itself. I lucked out and found it on the glove box, sometimes they even put it on the outside of the glove box on either side. Once I had this all I had to do was call the parts dept at the dealership and the guy gave me the code.
This should help

Anti Theft Radio Code (Honda Odyssey 2004


You have the wrong stereo code. No Honda stereo code has a 0.Your local dealership parts dept. should be able to supply the stereo code given the VIN of the vehicle or serial number of the stereo.
