I was talking to a counterman at a NAPA store in North Dakota yesterday. He said he needed a replacement keyless remote for his 2006 Chevy Silverado pickup. When he called his local Chevy dealer to buy the remote, he was told that this application required dealer programming with a scan tool. That information is incorrect.
This application is user programmable. For model years 2003-2006 Chevy Silverado used a 3-button keyfob with FCC ID LHJ011. Multiple OE part numbers were assigned to this part, but the most common GM part numbers are 15186203, 21997127 and 15132198. Some vehicles may have had seat memory. The seat memory remotes marked Fob 1 and Fob 2 on the back are interchangeable with keyfobs with no seat memory number. This same keyless entry remote was used on Avalanches, Suburbans, Tahoes, GMC Sierras and Yukons and even Hummer H2 during this period and all of these applications are user programmable.
We are not sure whether dealership personnel have bad information about programming or intentionally mislead customers to preserve business. In any event, the information received by this particular NAPA counterman was untrue. He seemed a little angry when I told him the dealer had not been honest with him.
