The lock that charges itself from a beam of light, with finger vein, palm vein and face on one door.
The V7 Max is the most expensive lock we list and the only one that powers itself from a beam of light, which makes it a specialist choice rather than a default one. It took CES 2026 Best of Innovation for that charging system, which Lockin calls AuraCharge. A small transmitter plugs into a socket inside the house, sits within about four metres of the door with a clear line of sight, and beams eye safe light onto a receiving panel on the inside of the lock. Two lithium packs inside the lock stay topped up, so nobody is pulling a battery out twice a year. TUV Rheinland and SGS both certified the optical output. The rest of the lock matches the price. The outside panel is 15.1mm thick and carries a 5 inch touchscreen, HD cameras, a finger vein reader, a palm vein reader and 3D face recognition. A second 5 inch screen sits on the inside panel. Matter is built in, so Apple Home, Google Home, Alexa and SmartThings all see it. Two things to be plain about. Lockin has taken its own V7 Max product page down, so part of what we know comes from the CES announcement and from the spec sheet its distributors publish rather than a live brand page, and we confirm the rest with the factory when we quote. It is also a mortise lock ordered left or right handed, so the door is measured and the handing fixed before anything ships.
A small indoor transmitter beams light at the lock from up to four metres away, so the packs top themselves up and charging stops being your job.
Three biometrics on one door, finger vein, palm vein and 3D face, so every person in the house has a method that works for their hands.Two cameras and a 5 inch outside screen make the lock the video doorbell too, with a matching screen on the inside panel.Matter is built in, so Apple Home, Google Home, Alexa and SmartThings all control the lock without a Lockin bridge.Model V7 Max

Three Dubai specifics decide this lock. First, heat. Lockin rates it from -20C to 55C, and a west facing villa door in July sits in direct sun for hours, so it belongs in a shaded or recessed entrance rather than on a bare sun struck door. Second, the transmitter. It plugs into a socket inside the house, within about four metres of the door and with a clear line of sight, so we look for a hall socket during the survey. In a flat that is usually easy and in a villa with a deep entrance hall it sometimes is not. Third, the door. It is a mortise lock with the handing fixed at order, and Dubai villa doors run thicker than European standard with the backset varying by developer, so we measure before ordering. Tower flats add a fire rated door and building approval to the list. Tenants need the landlord's written consent, and at this price that conversation happens first, not last.
Lockin in the UAE. Sold through UAE smart home retail. Its palm-vein and finger-vein locks read blood-vessel patterns rather than a fingerprint surface, which is a class of lock most brands here do not offer.
