A customer asked about a GM 3-button remote with FCC ID LHJ011. This keyfob was used on several GM trucks and truck-platform SUVs from 2003-2006, including Sierra and Silverado pick-ups, Escalade, Suburban, Tahoe and Yukon SUVs, and a variety of other vehicles. For all of the vehicles listed in this post, the keyless entry system in the vehicle can easily be programmed by a user to accept a new remote.
This FCC also appears on the case of a 4-button remote that a trunk release function. These systems were used on Saturn sedans and are not user programmable.
