Premium power. Professional results.

Official LiftMaster look at the Security+ 3.0 garage door opener lineup — quiet drives, battery backup, cameras, and myQ smart control.

Why homeowners upgrade

Battery backup

Power outage protection

Storms happen. With built-in battery backup on equipped openers, you can still open and close when the grid drops — so you’re not locked in or locked out.

A big reason homeowners choose a new garage door motor instead of another board repair on an aging unit.

Quiet drive

Nearly silent DC motor & belt

Quiet is why people pay for premium. A reinforced belt + DC motor is built for homes with living space near the garage — the kind of quiet garage door opener you notice the first morning after install.

Chain models are tougher for heavy doors; we’ll recommend the drive that fits your door, not just the quietest brochure.

Smart control

LiftMaster powered by myQ

One app for the garage door, cameras, and more — status, alerts, and close-from-anywhere when you leave for work or the kids leave the door up.

Advanced Garage Door sets it up so you’re not stuck in the app store on install day.

New opener vs. repair? About 10 years is the industry line we use. On a motor under that age, a failed logic board is often still worth repairing — the rest of the unit can have many good years left, so a board repair can beat buying a whole new garage door motor. Past 10 years, it is usually smarter to replace than keep stacking parts on an aging unit. Grinding is another solid signal to plan on a new motor (internal drive wear). Stopping mid-travel is not, by itself — that is often photo eyes, a spring/balance issue, or the door, not “throw the opener away.” Advanced Garage Door also handles garage door repair and spring replacement when the door is the real problem — we will tell you honestly which path fits.
