A professional-grade LiftMaster 87504-267 garage door opener kit typically retails between $500 and $700, depending on whether it is purchased as a standalone unit or bundled with professional dealer installation services, extra remote controls, or wireless keypads. Because LiftMaster products are distributed exclusively through authorized professional garage door technicians rather than big-box retail shelves, pricing varies based on local labor rates and installer markups. Verification: Request an itemized hardware and installation quote from a certified local LiftMaster dealer.
