2004 GMC Sierra 1500 4.3L (X LU3) 4-spd (4L60-E)

Customer called asking me about unlocking a radio for them, and if it has to match the RPO code in the glove box. Can it be unlocked via a scan tool [non tech2] as mine is broke, or will it need programmed. And can a different radio be programmed to the vehicle. I haven't done a replacement with a different RPO, and ever tried one w/o having a tech2 on hand, plus can't remember the last time i did one if ever. 

Thank, Brian

tech 2 or SPS will be required - strongly recommend matching RPO code of original build

I've always just called the local dealer (that I do business with) with the VIN and got the unlock code from them.

You should be able to unlock the radio with the Tech2. SPS started taking affect around 2006 or 07. I have upgrade the radio system in certain vehicles. You just have to decipher the RPO's which can be crazy depending on the YMM

Hi Brian, Any questions to whether this module, radio...require programming can me checked for free at tis2web​.​service​.​gm​.​com/tis2web FWIW - this does require SPS and I would stick with the same RPO code for the radio. Although you can upgrade from lets say a single disc to a 6 CD changer as long as it was an offered option for that vehicle.
