Dormakaba buys Alliants, pulling door locks and guest apps into one company

Dormakaba, one of the biggest names in hotel door locks, has agreed to buy Alliants, a UK guest experience software company. The deal puts physical access and the digital guest journey under one roof, and it is a signal worth reading for anyone choosing a check-in or mobile key stack.

The agreement was announced on 15 September 2026. Financial terms were not disclosed. Closing is expected within 2026, subject to regulatory approval.

Who Alliants is

Alliants was founded in 2009 in Southampton, United Kingdom. It builds guest experience software and provides managed services for hotels, and it says its platform covers more than 100,000 hotel rooms worldwide.

The product set is broader than the mobile key piece dormakaba is best known for. It spans concierge services, contactless check-in, mobile key, payments, guest messaging and what the company calls agentic AI. Alliants has delivered digital hotel keys into both Apple Wallet and Google Wallet, and TIME named that digital key technology one of the best inventions of 2025. The company employs more than 100 people.

"Hotel owners and operators increasingly view access and guest experience as part of the same strategy," said Till Reuter, dormakaba's chief executive.

"Access and guest experience stopped being separate problems some time ago; the industry's tooling just hasn't caught up," said Tristan Gadsby, Alliants' chief executive and founder.

What it means for operators

Neither company mentioned property management system integration in the announcement, which is the omission most worth noticing. Mobile key and contactless check-in only work if the PMS tells them who has arrived, which room they are in, and when the key should stop working. Alliants already has those connections. Nothing in the release says what happens to them, or whether dormakaba intends to keep the platform as open to competing lock hardware as it is today.

That is the question to put to your account manager. A software vendor owned by a lock manufacturer has a reason to make its own locks the smoothest path. It may well keep everything open, and plenty of acquirers do. But if you run Alliants on top of another manufacturer's hardware, or you were planning to, you now want that commitment in writing rather than assumed.

The broader pattern is familiar. Hardware companies in hospitality have watched the software layer capture the guest relationship, and the value with it. A lock is a lock. The app that opens it is where the upsell, the messaging and the data live. Buying into that layer rather than integrating with it is how an established hardware business stops being a commodity supplier.

For operators the practical near-term effect is nothing. Deals of this size take months to close and longer to show up in a roadmap. Contracts stay as they are.

The medium-term effect is one fewer independent option in a category that has been consolidating steadily. If you are running a procurement process for check-in or mobile key right now, it is worth asking each vendor on your list who owns them and who is likely to.
