2000 gmc sierra factory stereo

I changed my used sierra's battery and when I got power, my factory stereo locked up. The original owner can't remember the security code. Is there anyway to reset it without taking it to a GM mechanic?

Look behind the glove box, there should be a sticker with the code on it. or in the owners manual if you have one.

2005 gmc sierra, replaced radio with known good radio with same part # and model #, all functions work but there is no sound from the radio or the key and door chimes. Is this a lock feature. Took vehicle...


i cannot understand how you radio would work. These radios are coded throught data link to computer. the only way to get the stereo to work is to run a calibration program through the vehicle. then it should accept your new cd player. if the stereo's are the same then may I suggest you to take the radios appart and switch the parts that don't work like CD drive assembly and faceplate.but use your factory installed stereo as the main core, this should fix your isses and work fine since the calibration is for the origional factory stereo.

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

2000 gmc sierra 1500 5.3 v8. a/c heater control problem


your heat/cool and vent selection options are controlled by engine vacuum through small clear tubes attached to the rear of your climate control interface. Other vehicles have small steel pull wires that operate the desired changes. You might try removing the trim and any fasteners affiliated with the interface/console. GENTLY pull outward and look to see if any of these tubes are pulled off or cut/damaged. Did anyone recently install a new stereo in the vehicle? If so, the vacuum tubing and or pull wires that change your outlets could have been damaged when the stereo unit was pushed into place. Hope this helps

Installing an aftermarket stereo, spliced the wires and have everything connected including the remote wire to the factory amp wire but still no sound.


There is no remote wire on these newer trucks....03 and up....u have to buy the harness....although i didnt....i have an 03 gmc sierra and just pulled the schematic and matched the wires. And there is no programming to do on an aftermarket stereo.....I work for GMC and we cant program aftermarket stereos......if u buy the right harness ...and its over $100 then everything should work just fine.....and this does not disarm ur alarm system either....mine still works fine....hope this helps
