Newer southern subdivisions
Alpine, Cedar Hills, and Draper carry a lot of newer construction, closer to the 1999 median build year for this whole service area, so openers there tend to be factory remotes with circuit boards that fail from age rather than wear. Cottonwood Heights, Midvale, Holladay, and Murray sit on older stock, more typical of the 1980s-90s wave that defined much of this valley, and that means steel doors with original torsion springs that have simply cycled out their lifespan.
