The Yamiry unit is a knob-style lock, which matters more than any single feature. A knob replaces the whole handle assembly rather than sitting on top of an existing deadbolt, so the buyer gets the keypad and the lever in one piece. That makes it a simpler swap for a door that already uses a knob, and a more invasive job for one that uses a handle set or a separate deadbolt.

The feature set is squarely mid-tier. Twenty codes is generous for a household — enough for family, a cleaner, a dog walker and a short-term guest — and two backup keys mean the door still opens if the electronics fail. Auto lock and a backlit keypad are the two conveniences that separate this from a plain mechanical knob.

Build and Hardware

The product name describes a knob with a handle, so the buyer should expect a complete handle assembly rather than a bare cylinder. The keypad sits on the exterior face, with the backlit buttons arranged for one-handed entry in dim light. The interior side carries the thumb turn or lever that opens the door from inside.

The material question is the one to weigh carefully. At this price tier, knob locks of this type typically pair a metal interior chassis with plated or coated exterior trim, and the finish is what takes the weather. A covered porch or an interior-facing door treats that finish kindly; a door with full afternoon sun and no overhang is harder on it. Buyers in exposed locations should expect the cosmetic side to age before the mechanism does.

The knob form factor also sets a physical limit. A knob assembly fits standard door prep, but it is not a drop-in replacement for every door. Doors drilled for a handle set, or doors with a separate deadbolt above the knob, will need the old hardware removed and may need the opening adjusted. Measuring the existing bore before ordering avoids a return.

Codes, Keys and Power

Twenty user codes is the headline capability, and it changes how a household runs. A code can be issued to a guest and retired afterwards without rekeying anything, which is the whole point of going digital. The two backup keys cover the failure case — a dead battery or a keypad that will not read — so the lock is never purely dependent on electronics.

Auto lock is the feature that decides whether the household actually likes the lock. Set to lock behind the door, it removes the nightly check of whether the front door was secured, which is the single most common reason people buy a keypad knob. The trade-off is that auto lock is unforgiving of a door that does not swing freely; a door that needs a shoulder to close will fight the mechanism.

The backlit keypad is a small thing that matters every night after dark. Illuminated buttons mean a code can be entered without a porch light or a phone flashlight. Buyers should still plan on a battery routine — keypad locks of this class run on internal batteries, and the backup keys exist precisely because batteries eventually quit. Replacing them on a schedule rather than waiting for a warning is the habit that keeps a keyless door keyless.

Trade-off: A knob-style electronic lock at this price cannot match a heavy-duty deadbolt for physical resistance, and the exterior finish will show wear on a fully exposed door before the electronics give any trouble.

Installation and Fit

Easy installation is the claim in the product name, and for a like-for-like knob swap that is realistic. The job is a screwdriver task: remove the old knob, seat the new assembly through the existing bore, and fit the interior and exterior halves together. No wiring run is involved, which is what keeps this in do-it-yourself territory.

The variable is the door, not the lock. Standard knob prep is the easy case. A door with extra hardware, a metal skin or an unusual thickness turns a twenty-minute swap into an afternoon. Buyers who have never removed a knob should budget time for the first one and check the door’s existing holes against the product listing before ordering.

Renters should also think about reversibility. A knob swap is easy to undo at move-out, but keeping the original hardware in a labeled bag is what makes that true. Landlords generally accept a keypad knob more readily than a deadbolt replacement because the door prep is unchanged, though permission is still the renter’s call.

Who It Suits and Who It Does Not

This lock suits the household that wants to stop managing spare keys. Families with teens, households with a regular cleaner or dog walker, and owners of a short-term rental all get real value from twenty codes and a backlit keypad. It also suits the renter who wants keyless entry without altering the door’s prep.

It does not suit the buyer who needs a heavy-duty deadbolt, or a door drilled for a handle set rather than a knob. It is also the wrong pick for anyone who wants remote access, app control or entry logging — nothing in the product name suggests connectivity, so buyers should not expect it.

FAQ

1. What is the Yamiry keyless entry digital lock?
   It is a knob-style electronic lock for a front door, with a backlit keypad, twenty user codes, auto lock and two backup keys.

2. How many codes can be set on this lock?
   Twenty user codes. That is enough for a family plus regular help such as a cleaner or dog walker, with spares left over.

3. Does it come with keys in case the battery dies?
   Yes. Two backup keys are included, so the door can still be opened if the keypad or electronics stop working.

4. Does the lock close itself?
   Yes. Auto lock is listed as a feature, which means the door can be set to lock behind the user without a manual turn.

5. Is the keypad readable at night?
   Yes. The keypad is backlit, so codes can be entered after dark without extra light on the door.

6. Can it be installed without a locksmith?
   Easy installation is part of the product’s design. A like-for-like knob replacement is a screwdriver job, though doors with unusual hardware may need more work.

7. Will it fit a door that has a handle set or a separate deadbolt?
   Not directly. This is a knob assembly, so doors drilled for a handle set or a deadbolt above the knob will need the old hardware removed and may need the opening adjusted.

8. Does it work with a phone app or smart home system?
   Nothing in the product name points to app control or smart home integration. Buyers who want remote access should look at a connected lock instead.

9. Is it a good choice for a rental property?
   It can be. Twenty codes make it easy to issue and retire guest access, and a knob swap is simple to reverse at move-out if the original hardware is kept.

10. What is the main weakness of a knob-style keypad lock?
    Physical resistance. A knob lock does not match a heavy-duty deadbolt, and on a fully exposed door the exterior finish will show wear sooner than the mechanism fails.

Bottom Line

The Yamiry keyless entry digital lock is the right buy for a household that wants keyless entry on a standard knob-prepped front door without paying for connectivity it will not use. Twenty codes, auto lock and two backup keys cover the daily job, and the backlit keypad handles late arrivals. Buyers who need deadbolt-grade security, app control or a fit for handle-set doors should keep looking — but for the common case, this is a sensible, low-friction upgrade.
