Our take
The Approach looks better than most retrofits and is often on sale. Reviews are mixed on reliability, so it’s the pick for deal hunters rather than the default.

What we like
- Tom’s Guide’s best budget smart lock (July 2026)
- Slimmer than August
- Frequent deep discounts
Watch out for
- PCWorld hit calibration and firmware glitches
- Sources disagree on whether remote access needs a bridge
Skip it if you want the smoothest, most proven setup. August is the safer choice.
