Latch is now DOOR: how its connected-building platform works

Getting into an apartment building used to mean collecting a key, a fob and a list of codes. Latch, now operating as DOOR, is building a system that turns that collection of physical credentials into a connected service for residents, property managers, visitors and maintenance teams.

At its centre is access control: smart locks, readers and intercoms connected to cloud software. But the company’s ambition is broader. DOOR combines those devices with smart-home controls and property data, with the aim of helping a multifamily building manage daily tasks from one platform.

How the system works in a building

A resident can use the DOOR app, a doorcode or an authorised keycard to enter the spaces they are allowed to use. A property manager uses DOOR OS, the browser-based management tool, to add or remove access, configure a property and manage connected devices. The same model can cover apartment doors, building entrances and common areas such as gyms, garages and delivery spaces.

This is useful because access changes frequently in rental housing. A new resident moves in, a contractor needs temporary entry, a lost credential has to be disabled, or a cleaner needs access only during a limited time window. A connected system can change those permissions without a manager having to rekey a lock or hand over a physical key each time.

From smart locks to building operations

DOOR’s platform also supports smart-home devices and integrations with equipment such as sensors, thermostats and lighting. The company describes the longer-term goal as “building intelligence”: using access, device and property information to make operations less manual. In practice, that can mean helping a manager coordinate work orders, maintenance, inspections and repairs alongside everyday access management.

The difference between that idea and a conventional smart lock is the operating context. A single connected lock solves a door problem. A multifamily portfolio needs an auditable way to manage many doors, users and service providers without creating confusion about who can enter where. Reliability, battery management, privacy, integration and staff training matter as much as the app experience.

DOOR’s own support material shows the practical nature of the system. For example, a Latch Intercom is paired to a building entrance through the DOOR app and DOOR OS; it works with a corresponding access device rather than functioning as a stand-alone unlocker. That is a small detail, but it illustrates why a connected-building installation is a system design exercise, not simply a hardware purchase.

The hand-off between manager and resident

The system changes hands several times during an ordinary tenancy. A building team sets up the property and its connected devices. A resident receives the access methods that the property enables. Visitors, delivery staff and service providers can be given access under the policy chosen by the building, rather than receiving a permanent physical key. When a tenancy ends, a manager can remove access from the system instead of collecting and reissuing every credential.

That workflow is one reason multifamily operators use connected access. An apartment building is not one front door with one owner. It is a changing network of private homes, shared facilities, entrances and working spaces. The access policy has to recognise the difference between a resident entering an apartment, a guest arriving at a lobby, a technician attending a scheduled job and an employee managing the property.

The practical test comes when something is not routine. A resident may lose a keycard, change phones or arrive when a device is offline. A manager may need to grant access during a repair while protecting other residents’ privacy. DOOR’s value rests on whether its devices, app and management tools make those exceptions easier to resolve without turning daily building access into a support problem.

Why the name changed but the company did not

Latch emerged in the 2010s with a focus on smart access for multifamily properties. It became public in 2021 through a business combination with TS Innovation Acquisitions Corp. The customer-facing business was rebranded as DOOR in August 2025, while the legal public-company name remained Latch, Inc. Latch Systems, the principal operating subsidiary, was renamed DOOR Systems.

That distinction matters when checking news or filings. The product, app and website are branded DOOR, but corporate documents can still carry the Latch, Inc. name. The company’s common shares continue to trade over the counter as LTCH, rather than under a new DOOR ticker.

A narrower operating focus in 2026

In its second-quarter 2026 update, Latch said it planned to exit the DOOR Property Management business and reduce its workforce as part of a cost-reduction plan. The stated focus was the core building-intelligence platform, including AI-enabled software capabilities and product development. A planned exit should not be confused with an instantly completed transition, but it indicates where the company is directing resources.

For property owners, this focus makes the evaluation straightforward. The important question is whether access control, resident tools and building operations work together well enough to reduce routine workload. Hardware specifications matter, but so do deployment support, existing-building compatibility, integrations with property-management software, incident response and the way access data is handled.

What residents should expect

For residents, the benefit is convenience: fewer physical keys, clearer guest access and a way to manage an enabled home from one app. The trade-off is that access becomes dependent on a property’s device setup, account permissions and support process. Residents should know which access method works if a phone battery dies, whom to contact if a device fails and what access activity their property manager can view in common areas.

DOOR’s product FAQ outlines the company’s integrated approach to locks, access control and building automation. It is a useful starting point for understanding the product, although the right installation will still depend on the individual property.

DOOR’s story is therefore not just a rebrand. It is an attempt to turn the familiar problem of opening a door into a managed layer of building operations—one that has to earn its place by being secure, dependable and simple for the people who use it every day.
