Lever-handle smart locks replace the tubular latch already sitting in your door. On a standard hinged door that is a drill-and-swap job rather than a rebuild — which is why this is where most people start, and why it is the closest thing to a like-for-like upgrade in the whole smart door lock range.
Both locks here open five ways: fingerprint, keypad code, RFID card, phone app and a mechanical key. The difference between them is not features. It is how much measuring you want to do.

If you have measured your backset and it reads 60 or 70 mm, the doorbell model is better value and adds a doorbell. If you would rather not measure precisely, the adjustable-latch model puts the part that usually goes wrong in the box, and handles far more users — useful for a share house or a small office.
Will one of these fit your door?
Both suit hinged doors between 35 and 55 mm thick with a stile at least 96 mm wide. The measurement that decides it is the backset, and each product page has a calculator that asks you for it. The sizing guide shows exactly where to put the tape.
If your tape reads 45 or 50 mm you have a European fitting and neither of these will go on — look at the 4585 option in the push/pull range instead. If your door is aluminium-framed with a narrow stile, the camera lock at a 22 mm backset is the one built for it.
Neither lock here carries a weather rating. Fit them to an internal door, or to an entry that sits under an eave, a porch or a roof overhang. If your door takes direct rain, the IP66 gate lock and the IP66 push/pull range are the two that are built for it.
Push/pull instead?
A lever is what most homes already have, so it is the easiest swap and the most familiar to live with. A push/pull handle is easier again if you routinely arrive with an armful of shopping or you have limited grip strength — you lean on it going out and pull it coming in, with no turning at all. It also happens to be the range that is weather-rated.

Why a lever is the easiest upgrade
A lever handle driven by a tubular latch is what most homes already have on a hinged door. Because the smart version uses the same bore and the same latch pocket, fitting one is a swap rather than a rebuild — usually under an hour with a drill, a screwdriver and the supplied template.
That also makes it the cheapest way into the category. You are not paying for a mortise body, a camera, a screen or a weather seal you do not need. If your door is sheltered and standard, this is the rational place to start, and our buying guide reaches the same conclusion by a longer route.
Living with one day to day
The fingerprint is what you will use, several times a day, without thinking. The code is what you give someone over the phone. The card is for the cleaner. The app is for the times you are not there, and the mechanical key is the one you will use once in five years and be very glad exists.
Both locks store enough fingerprints, codes and cards for a household several times over. Where they diverge is user management: if you are running a share house, a holiday let or a small office, the adjustable-latch model handles nine administrators and 291 users, which the entry model does not.
Batteries last around twelve months and the lock warns you long before they go. If you ignore the warning, there is a USB port on the outside face — a phone power bank wakes it up. Details in the FAQ.
