Lenovo F3 smart lock: solar-assisted palm vein and face entry with two cameras, a 5-inch indoor screen and Alexa, Google or Siri, for bright Dubai villa doors.
The Lenovo F3 is the solar-assisted palm vein smart lock to choose in this push-pull range when your Dubai front door gets real daylight, because it is the only one that tops up its own battery from light. It suits villa owners who want palm vein and face entry without regular charging. A radar sensor wakes the lock as you walk up. You then show your face to the camera or hold your palm over the reader, which checks the vein pattern under the skin, and push the handle. Fingerprint, PIN code, card and a mechanical key are there as backups. A solar strip on the panel feeds the 5000mAh battery whenever the light on the door passes 5000 lux. When someone rings, the call reaches the Tuya Smart Life app with live video, so you can talk and open from your phone. What else you need: Wi-Fi that reaches the door, a door between 40 and 100 mm thick, and a mortise cut-out that suits the lock body. Lenovo's sheet lists the mortise two different ways, so we confirm which body ships before you pay. The 70°C rating covers a sunny villa porch. The honest limit is location. Inside a tower corridor the solar strip does very little, so an apartment owner pays extra for a feature that will not help, and fire-rated entrance doors need building approval first. For a shaded or indoor door, the X6F or A6F gives better value.

Most villa main doors in Dubai take a European mortise lock body, and the F3 is made for that kind of door. Before you order, we measure the door thickness, the existing cut-out and the gap at the frame, then confirm with the supplier which mortise body comes in the box. A west-facing door in July is well inside the 70°C rating, though a dark panel in afternoon sun runs hotter than the air, so a porch roof still helps the screen and battery age slowly. Dust settles on the solar strip fast here, and a dusty strip charges less, so add it to the weekly wipe. During a DEWA power cut the lock carries on from its battery; only app access drops until the router is back. Apartment buyers should clear two things first: landlord consent and the building's rules on fire-rated entrance doors.
Lenovo in the UAE. Lenovo-branded smart locks and cameras are made by Yunka Intelligent (Shenzhen) under licence as part of Lenovo's smart-device ecosystem, rather than by Lenovo's computer business. Most of the locks run on the Tuya / Smart Life app, while the cameras use the cam720 app. UAE availability is patchy: a few models are stocked by specialist smart-lock retailers and many are sourced to order, so we confirm the exact model, lock body and lead time before quoting.
