2007 - 2010 How to VIN Unlock Salvage Yard GM Radio w/ Tech2 OR Manually Programming its EEPROM

In this video I show you TWO ways to UNLOCK an used salvage yard Delphi / Delco Electronics showing LOCKED on the display for 2007 up thru 2010 designs. Shown by using the GM Tech2 scan tool OR instead by using an inexpensive CH341a EEPROM programmer to manually update the VIN stored inside the radio. Both methods do NOT involve any soldering (for this part number), hacking, destruction, or damaging of the radio circuit board or its chip(s) and thus preserve 100% of the functionality as originally designed by GM - while still clearing the VIN Theftlock correctly. However, to perform the remedies in this video you need to either have access to a GM Tech2 scan tool and CANDi module, or alternatively a GM MDI scan tool with a paid Tech2Win subscription at www.acdelcotds.com, or an EEPROM programmer capable of programming for a SOIC8 24C08 EEPROM (marked 09400464 by Delphi).

NOTE: Some radio models have a circuit board design that is incompatible with in-circuit programming, and for these a test clip WILL NOT work. You will have to instead desolder and remove the EEPROM chip if you are having problems reading it in circuit (e.g., getting all 00s). I can only confirm this particular salvage Delphi radio with GM part 25834576 will work in-circuit.

I illustrate both procedures using a benchtop test harness constructed out of a salvage 2009 Chevrolet Cobalt Body Control Module (BCM). The video is an exact match for unlocking the radio on a 2007, 2008, 2009, or 2010 Chevrolet Cobalt or Pontiac G5 with the US8 radio head unit GM part 25834576 and BCM 25928052. This video is NOT going to apply to older vehicle Theftlock style radios, and is somewhat different than the previous generation RDS radios too - I have other videos for both of those - check my playlist. I make no claims this videos approaches are applicable at all if you're outside these particular GM model years.
