The A2 Double-Sided Stainless Steel Smart Lock is a durable and versatile locking solution designed for various door types, including aluminum profile doors, security doors, and courtyard gates. Crafted from 304 stainless steel, it ensures both robust protection and a sleek appearance. Supporting multiple access methods, it caters to modern security needs while offering convenience and adaptability. The lock fits doors with thicknesses ranging from 40mm to 120mm, making it suitable for residential and commercial installations.
send inquiryMost smart locks assume one side of the door stays free and open — a mechanical thumbturn on the inside, smart access only on the outside. But that assumption doesn't hold everywhere. The A2 Double-Sided Stainless Steel Smart Lock was built for the doors where it genuinely doesn't hold — placing full smart panels on both the front and rear sides, which makes it a natural fit for aluminum profile doors, security doors, courtyard gates, and any entrance where access actually needs managing from both directions at once.
Visually, the lock keeps a long black touchscreen panel, complete with a digital keypad, a lower sensor area, and a horizontal lever handle. Handle color comes in black or silver, so the same lock body can be paired to match whatever door style it's going on. The overall look stays clean and modern enough to work across residential entrances just as easily as commercial ones.
304 stainless steel makes up the build, chosen with frequent daily use and semi-outdoor exposure in mind. Profile doors and courtyard gates in particular tend to face rougher conditions than a typical interior door — more handling, more humidity, more general wear — and stainless steel is what lets the A2 resist corrosion, wear, and deformation under that kind of pressure.
Here's a closer look at what actually sets the A2 apart, beyond just having two panels instead of one.
As a Double-Sided Smart Gate Lock, the A2 puts a fully intelligent access panel on each side of the door — not a keypad on one side and a basic mechanical knob on the other. Both sides show a proper keypad interface, which means entry and exit both stay under controlled access rather than one direction being wide open by default.
That structure proves genuinely useful across:
Wherever access truly needs managing from both directions, the A2 offers a level of control a single-sided smart lock simply can't match.
Lower sensor areas visible on both panels reflect the A2's identity as a Double-Sided Fingerprint Door Lock, working alongside keypad access to give different users a convenient, controlled way through the door from either side.
Depending on configuration, supported access methods can include:
That flexibility carries over well into both residential settings and more formally managed access environments.
Crafted from 304 stainless steel, the A2 holds up structurally against corrosion — a genuinely important quality given that aluminum profile doors, security doors, and courtyard gates all tend to see frequent touch, humidity, and some degree of outdoor exposure over their lifespan.
That same stainless steel structure supports long-term reliability across residential buildings, offices, and other controlled entrance points where hardware needs to keep performing year after year.
Door thickness compatibility runs from 40 mm to 120 mm, giving the A2 room to adapt across varied installation conditions.
It works comfortably on:
For projects juggling multiple door types but wanting one consistent smart lock solution throughout, that range of compatibility genuinely simplifies things.
The dimension image lays out the key specs:
It also shows a mortise lock body running through the door, with smart panels mounted on each side — a useful reference for installers and project teams confirming door compatibility before moving ahead with installation.
The A2 Double-Sided Stainless Steel Smart Lock fits doors and gates where smart access genuinely needs to work in both directions, not just one.
| Application | Usage Description |
|---|---|
| Aluminum Profile Doors | Double-sided access control for narrow or framed door systems |
| Security Doors | Fits residential and commercial security entrances |
| Courtyard Gates | Controlled entry and exit for outdoor or semi-outdoor gate areas |
| Shared Entrances | Useful where access needs managing from both sides of the door |
| Commercial Rooms | Fits restricted rooms, offices, or facility doors |
| Residential Gates | Suited to villas, private courtyards, and controlled home entrances |
For doors where the inside genuinely can't stay freely accessible to everyone, the A2 fills a gap most single-sided smart locks simply weren't designed to cover.
