# GlobalLockSummary

> Open knowledge base of the world's mechanical door locks: identify the lock you have, record its dimensions, and design the smart-lock retrofit that fits it.

An open, machine-readable reference for identifying existing mechanical door locks worldwide and designing smart-lock retrofits that fit them. All data is also available as JSON at /data/catalog.json.

## Retrofit design
- [Retrofit architectures](/retrofit.html): the seven architectures, adapters and design targets
- [motor-on-thumbturn](/retrofit/motor-on-thumbturn.html): A geared motor clamps over the existing cylinder body on the inside of the door and turns the thumb-turn (or a key left 
- [integrated-cylinder](/retrofit/integrated-cylinder.html): The cylinder itself is replaced by a cylinder with the motor, battery and radio inside. The outside keeps a mechanical k
- [interior-handle-motor](/retrofit/interior-handle-motor.html): The interior lever or knob is replaced by a motor unit that drives the 8 mm spindle directly. The outside keeps the orig
- [surface-deadbolt-motor](/retrofit/surface-deadbolt-motor.html): An adhesive or screw-fixed motor sits on the door face and rotates the existing deadbolt turn-piece. Nothing is drilled.
- [full-lock-replacement](/retrofit/full-lock-replacement.html): The old lock case is removed and a smart lock with the same footprint takes its place. This is the dominant approach in 
- [rim-lock-motor](/retrofit/rim-lock-motor.html): A motor unit is fixed to the surface-mounted rim lock case or to its knob, driving the latch or the deadbolt. Common on 
- [gate-actuator](/retrofit/gate-actuator.html): Metal security gates get a dedicated actuator: a motor pulls a lever or a chain, or an electromagnet releases the gate l

## Lock families
- [Australian deadlatch and deadlock](/locks/au-deadlatch.html): A surface deadlatch with a key outside and a knob or slide inside, plus a separate deadlock on many doors. Mechanically close to the UK nigh
- [Euro profile cylinder in a mortise case (DIN)](/locks/euro-cylinder-mortise.html): The most standardised lock family on earth. A 17 mm × 33 mm profile cylinder sits in a mortise case built to DIN 18251, driven by an 8 mm sq
- [Indian mortise handle set, rim nightlatch and cylindrical lock](/locks/in-mortise-rim.html): India is the clearest example of why a retrofit cannot be designed per country. Three incompatible interfaces share one market: a euro-profi
- [Japanese mortise case and cylinder (MIWA / GOAL style)](/locks/jp-miwa-case.html): Japan has its own dominant makers and its own case geometry, with a backset commonly around 64 mm rather than the European 55/60 mm. Replace
- [Korean push-pull digital lock base (mortise)](/locks/kr-pushpull-mortise.html): The design language that dominated Asian smart locks for a decade: a tall push-pull handle set replacing an entire mortise lock set. It is a
- [Multipoint locking system (uPVC / composite)](/locks/multipoint-upvc.html): One cylinder and one handle drive hooks and rollers at three or more points along the door edge through a gearbox. The handle must be lifted
- [Padlock, hasp and staple](/locks/padlock-hasppad.html): The oldest interface on this site and still the most common lock on outbuildings, gates and shutters. Retrofit here is not about the lock at
- [Rim nightlatch (surface-mounted)](/locks/rim-nightlatch.html): A surface-mounted case on the inside of the door with a cylinder through the door face. Pulling the inside knob retracts the latch; the outs
- [Singapore HDB main-door mortise set and metal gate lock](/locks/sg-hdb-mortise.html): A two-door entrance: a fire-rated timber main door with a mortise lock set, and a metal security gate with its own latch. Most Singaporean r
- [Singapore HDB metal security gate lock](/locks/sg-metal-gate-lock.html): The second door of a Singaporean entrance, and the one that defeats most smart-lock products. It is a metal gate, not a door: bars instead o
- [5-lever mortice deadlock (BS 3621)](/locks/uk-5-lever-mortice.html): A lever lock keyed from both sides, with no cylinder at all: the key moves the levers directly through a keyhole in the faceplate. BS 3621 c
- [UK oval cylinder (uPVC and composite doors)](/locks/uk-oval-cylinder.html): The cylinder on most British uPVC and composite doors. It is oval rather than round-profiled, sits in a multipoint gearbox, and is the compo
- [Bored lever or knob set (ANSI/BHMA A156.2)](/locks/us-bored-lever.html): Two bores: a 2-1/8 in cross bore through the face for the knob, and an edge bore for the latch. Dimensions are so consistent that a retrofit
- [Single-cylinder deadbolt (ANSI/BHMA A156.36)](/locks/us-deadbolt.html): A separate round lock above the handle: key outside, thumb-turn inside, 1 in bolt throw. It is the single most retrofit-friendly lock in the
- [Mortise lockset (ANSI/BHMA A156.13)](/locks/us-mortise.html): The commercial workhorse: a large case in a pocket in the door edge, with a huge function catalogue (passage, entry, classroom, storeroom, e
