2003 04 05 Unlock XM Lock Error on Salvage Yard GM XM Receiver (Buick Cadillac Chevrolet Pontiac)

Описание: In this video I'll show you how to fix the XM Lock (or XM Locked) error message shown on the factory radio head unit display when you attempt to replace your defective original, and now discontinued by GM, Delphi Digital Radio Receiver (DRR) module (aka "XM Radio") with a salvage yard unit for these years for repair purposes. Even if you obtain the exact same Delphi Delco Electronics GM part DRR number from the exact same make, model and model year vehicle - the GM dealers Tech2 or MDI tools CANNOT clear the VIN related XM Lock that results! This is a huge difference from the regular radio head units and makes XM receiver repair more challenging skill wise.

This limitation is simply because, for a variety of security and piracy control reasons, GM and SiriusXM did not permit customers swapping S-band XM receivers between vehicles even at the dealer level. But GM no longer sells these parts, so how can you LEGALLY REPAIR your vehicle today? Well, rather than damaging or modifying the DRR circuit board or its EEPROM memory with novice hacks, I show you how you can professionally correct this error condition without any loss of the factory designed XM radio functionality.

Like the Body Control Module (BCM) on some vehicles of this same era, the Delphi part 9355093 EEPROM chip (which in the video I show is nothing more than an ST 24C08 EEPROM) on the circuit board of these modules was a write-ONCE process for the VIN by the Tech2 setup programming. Any attempts to change an already existing VIN that has been stored were blocked by design for anti-piracy / security reasons. In this video we go over how you get around this situation with the right electronics tools by opening up the unit and either transferring the EEPROM chip between units (preferred), or alternatively changing overwriting the VIN information contained on the EEPROM itself without damaging or modifying either the EEPROM chip or circuit board. I'll also explain a couple of different Delphi DRR board designs you can encounter within these years as well as the significance of the VIN vs the radio ID to your XM Radio account at SiriusXM.

VERY IMPORTANT NOTE: Even after you successfully unlock the DRR after you transfer the EEPROM chip between units, or alternatively just overwrite the VIN, you will STILL need to call SiriusXM to change the RadioID on your account there (because the Radio ID isn't something you can change in the EEPROM so you'll have to switch your account to the one from the salvage yard unit going forward). This is no different than what you would do if you replaced the factory unit with an aftermarket XM radio.

While the theme of vehicle in this video is the 2003-2005 Chevrolet Cavalier and Pontiac Sunfire, this video applies specifically to any vehicles with DRR module GM part numbers 22692861 and 22729350. And to model years 2003, 2004, and 2005 for all of the following Buick, Cadillac, Chevrolet, GMC, and Pontiac vehicles with regular production option (RPO) U2K:

2004-2005 Buick Rendezvous
2004 Cadillac CTS
2003 Cadillac Escalade
2003 Cadillac Escalade EXT
2004 Cadillac SRX
2005 Chevrolet Corvette
2004-2005 Cadillac XLR
2003 Chevrolet Avalanche
2003-2005 Chevrolet Cavalier
2004 Chevrolet Colorado
2005 Chevrolet Equinox
2003 Chevrolet Silverado
2003 Chevrolet Suburban
2003 Chevrolet Tahoe
2004 GMC Canyon
2003 GMC Sierra
2003 GMC Yukon
2003 GMC Yukon XL
2004-2005 Pontiac Aztec
2003-2005 Pontiac Sunfire

This video may certainly be applicable to model year parts for DRRs before 2003, and usually applicable to those thru 2010 (but not likely applicable past 2010).
