Does a software approach cover unit doors the way Latch does?

No. Latch sells smart locks for unit doors alongside building entry, while a buzzer app controls the building's front entrance only. If per-unit smart locks are a hard requirement, you need lock hardware regardless; many buildings pair a buzzer app for the entrance with whatever lock or lockbox each unit already uses.

Can I trial a software option on one building before rolling it out?

Yes, and that is the practical advantage. You add one building, have its panel dial the new virtual number, and run it for a trial period with zero construction. Rolling out to the rest of a portfolio is repeating a directory change per building, and rolling back is just pointing the panel at the old number again.

What does an access ecosystem lock you into?

Hardware ecosystems couple the door hardware, the software subscription, and the vendor roadmap. If pricing or the product changes, switching means replacing physical equipment. With a software layer on a standard telephone-entry panel, the panel stays neutral and switching costs are an account change, not a construction project.

Latch Alternatives Without Hardware Installation

By Ty · 2026-07-06

Latch pitches a whole building operating system: smart locks on unit doors, intercom at the entrance, one app for everything. It is a real ecosystem, and that is exactly the problem if all you actually need is for the front-door buzzer to stop ringing one person’s phone. The full package means hardware on every door, installers in every building, ownership sign-off, and a subscription sized for an amenity program rather than a fix.

Most buildings shopping for a Latch alternative are really shopping for one piece of it: modern control over building entry. If your entry panel already dials a phone number when a visitor selects a unit, that piece does not require new hardware at all.

How to fix it

Option	Pros	Cons
Latch	Unit smart locks plus entry in one ecosystem, strong for new construction	Hardware on every door, installation, subscription, owner approval
ButterflyMX	Video intercom at the entrance, delivery PINs	Panel purchase and install, board decision, per-building rollout
Panel replacement (DoorKing, Linear)	Modern managed directory on proven hardware	Capital cost and installer time per building, no resident app frills
Keep the buzzer on a personal phone	Free, no changes	Every arrival depends on one person answering, nothing is logged
Lowkey	Auto buzz-in, passcodes, scheduled vendor access, entry history, no construction	Quick one-time setup with your building

Choose the ecosystem if you are outfitting new construction or ownership wants smart locks on every unit door. Choose the software layer if the pain is the entrance: deliveries, vendors, and guests getting buzzed in reliably without a human answering every call.

Where Lowkey helps

Lowkey upgrades the entrance without touching the building. The existing telephone-entry panel dials a virtual number instead of a personal phone, and from the app you get automatic buzz-in, 4-digit passcodes for the keypad, recurring windows for cleaners and maintenance, and a full activity history per building. It works with any buzzer that dials out to a phone number, which covers most apartment and condo systems. For operators, one account manages every building with the whole team on board, so a portfolio gets consistent entry control in days, one directory change per building, and nothing to install.
