A brand new professional-grade LiftMaster 8500W jackshaft garage door opener kit typically retails between $400 and $600, depending on whether it is purchased as a standalone unit or bundled with an automatic garage door lock, wireless keypads, remote controls, and professional dealer installation services. Because LiftMaster products are distributed exclusively through authorized professional garage door technicians rather than big-box retail shelves, pricing varies compared to standard consumer brands. Verification: Request a formal itemized quote from a certified local LiftMaster dealer to compare active equipment and labor costs.
