Community Reviews

Eufy Smart Lock C33 is best suited for indoor or covered, lower exposure doors where access tracking and NFC convenience matter more than heavy weather protection. The lock is described as not a deadbolt, with both sides using levers, so it fits rooms, dorms, roommates, stockrooms, or other controlled spaces better than a main entry. Battery life and fingerprint reliability are the biggest concerns, especially with sweat, Wi Fi use, and some older models. The IP53 rating is only comfortable for a covered porch, making this a niche fit rather than a front door workhorse.

  • Apartment managers tracking access in stockrooms or shared rooms, because managed access control and frequent entry are where this lock shines.

  • Households using interior bedroom or roommate doors, because the lever-only design fits rooms inside a home better than a main entry.

    Ride_The_Sky

  • Covered-porch installations, because the IP53 rating is enough for sheltered weather but not heavy direct exposure.

    IndigoWinter2667

  • Owners who can tolerate occasional charging, because one long-term setup needed a recharge every five to six months.

    omar10wahab

  • Buyers who want long battery life on a Wi-Fi lock, because battery life can be abysmal and may drop to a few months or less.

    ginuwinqbinJackie8zrsax777ColinW5259

  • Front-door entrances, because the lever-only design is better suited to interior doors than a primary entry.

    ArkusRide_The_Skykikilicious

  • People who need reliable fingerprint unlocking with sweaty hands, because the sensor can fail to scan properly when fingers are damp.

    ginuwinqbinJackie8zSauloP

  • Rain-exposed exterior doors, because the IP53 rating is not trusted for long-term heavy direct weather.

IP53, not the best water rating but its enough for a covered porch. I wouldn't trust it long term in heavy direct weather.

I have the deadbolt version and the fingerprint sensor isn't good. Got some random Chinese door knob with a fingerprint sensor and it is much better. You'd think Eufy would have better sensors...

Very good point!
These type of locks are likely best for office or dorm like areas, not the best for primary entrances.

FYI: this line of Eufy smart locks are suspectable to picking via the physical key slot. Usually a simple wave rake is all you need. This also means likely I could use a paperclip with a bent end also, and another for tension.

Try the Tapo lock. I switched from Eufy and will never go back. Battery is rechargeable and still at 100% 2 months later and gets used a bunch everyday. I put 3 in. Response time is really good to.

My other Eufy locks have been rock solid. I have a ton of them on multiple rental properties. Will check Tapo out though. Thansk for rec.

I too had the same experience. I don't know if they improved them but the battery life was abysmal. I returned it.

I have had a eufy battery powered deadbolt lock over 3 years now. Battery life is great for mine still to this day. Maybe charge it every 5-6 months. I have it connected to home assistant as well which notifies me if the battery gets low. Mine does have a way to power with an external battery pack but I've never used it and it's not a problem for me.

Home assistant showing I charged July 6th and battery got low October 31st which is the last time I charged it

If you have an iPhone & Android household, and your phones support UWB technology, you should check out the new Aqara U400. You'll be able to walk up to the door, and it'll automatically unlock. I plan on putting my U100 on the back door once I grab one of these. Gonna wait for a sale, of course.
