Global Indigenous Lock Standards & Identification Matrix
Engineered for overseas smart lock developers. Consolidating indigenous mechanical tolerances, mortise cutting logic, and error-proofing guidelines across DACH (DIN), France (NF), Japan (JIS), UK/ANZ (AS/BS), LatAm (ABNT), and North America (ANSI).
📍 Quick Navigation:
🇩🇪 DACH (DIN)
🇫🇷 France (NF)
🇯🇵 Japan (JIS/MIWA)
🇦🇺 UK & ANZ (AS/BS)
🌎 Latin America (ABNT)
🇺🇸 North America (ANSI)
🇩🇪 DACH Region: Dornmaß, PZ Dimensions & Dual-Action Clutch
DIN 18251 / DIN 18252
- Dornmaß (Backset): Standard 55/65mm for timber, 35-45mm for profile doors.
- PZ (Centres): Standard 72mm for entrance, 92mm for fire doors.
- Gefahrenfunktion (Emergency Clutch): Cylinder must feature BS dual-clutch; otherwise lockout occurs when motor stalls.
Recommended Adapter: ADP-02 (8-to-9mm panic sleeve) + ADP-06 (key clamp)
🇫🇷 France & Belgium: Axe 50, Entraxe 70 & 7mm Spindles
NF / Vachette 70
- Entraxe (Centres): Strict 70mm centres (differs from German 72mm); mixing causes latch binding.
- Axe (Backset): Standard 50mm, with older buildings featuring 40mm.
- Fouillot (Spindle): 7x7mm square hole. Standard 8mm spindle cannot fit without adapter.
Recommended Adapter: ADP-01 (7-to-8mm brass sleeve)
🇯🇵 Japan: Faceplate Engraving Decoding & Anti-Theft Thumbturn
JIS A 1510 / MIWA / GOAL
- フロント刻印 (Faceplate Engraving): Marking MIWA 13LA determines 64mm backset & CAD cutting pocket directly.
- 防犯サムターン (Pinch Thumbturn): Thumbturn has spring-loaded pinch tabs. Direct motor drive stalls without release adapter.
Recommended Adapter: ADP-03 (MIWA B5 pinch gripper)
🇦🇺🇬🇧 UK & Australia: Rim Nightlatches & Lockwood 001 Deadlatches
AS 4145 / BS 3621
- Lockwood 001 (Australian Deadlatch): Teardrop knob (48x34mm); auxiliary bolt must depress fully into strike box.
- Door Gap False Lock Risk: Gap >3.5mm causes false lock where door can be carded open.
Recommended Adapter: ADP-05 (Teardrop turn adapter) + ADP-07 (Strike shims) + ADP-10 (Cover plate)
🌎 Latin America: 40mm Narrow Entrada & Pivot Roller Latches
ABNT NBR 14913 / IRAM
- Entrada 40mm (Narrow Backset): Brazil standard 40/45mm backset. Standard wide smart locks collide with door frames.
- Porta Pivotante (Pivot Doors): High-end pivot doors use roller catches; smart locks require standalone latch drive.
Recommended Adapter: ADP-08 (Door reinforcer)
🇺🇸 North America: 54mm Bore & Flat Tailpiece Deadbolts
ANSI / BHMA A156.36
- Cross Bore 2-1/8" (54mm Cross Bore): Universal 54mm cross bore across US homes for door thickness 35-45mm.
- Tailpiece (Tailpiece Cam): Schlage thick cam vs Kwikset thin cam require universal stepped adapter.
Recommended Adapter: ADP-04 (Universal tailpiece cam) + ADP-07 (Anti-binding shims)
📖 Global Locksmith & Hardware Specification Jargon Cheat Sheet
When communicating with overseas locksmiths, architectural hardware consultants (AHC), and cross-border B2B distributors, the following industry acronyms are standard:
| Acronym | Full Industry Term | Engineering Definition | Smart Retrofit Impact |
|---|---|---|---|
| KA | Keyed Alike | Multiple cylinders operable by a single identical key pattern | Common in residential front/back doors. Retain existing core or offer rekey kit. |
| KD | Keyed Different | Each cylinder has an independent, unique keyway pattern | Standard out-of-box cylinder; 100% ideal for key-gripper retrofit adapters. |
| MK | Master Keyed | Hierarchy where individual tenant keys open one door, master opens all | Strictly prohibited to replace cylinder in multi-tenant lease. No-drill retrofit is mandatory. |
| BS | Backset (Dornmaß) | Distance from edge of door to center of keyhole/spindle bore | NA: 60/70mm; DE: 55/65mm; FR: 50mm; JP: 51/64mm; LatAm: 40mm narrow stile. |
| PZ | Profilzylinder Distance | Center of handle spindle to center of euro cylinder round profile | Euro dividing line: 72mm (interior timber) vs 92mm (entrance / multipoint / fire door). |
| US26D | Satin Chrome / Brushed Chrome | ANSI BHMA 626 Satin Chromium Plating | Benchmark architectural finish for commercial & apartment retrofit hardware. |
| US19 | Flat Black / Matte Black | ANSI BHMA 622 Electrostatic Matte Black | Fastest growing residential modern smart home finish, now exceeding 45% volume. |
