Locker locks are installed in their hundreds, and the total cost of ownership is then decided by what happens after installation: batteries to buy and change, service visits to plan, cabling to lay and move. In a worked example with 300 lockers over ten years — Focus Security's own adjustable assumptions, to be replaced with each site's actual figures — battery operation alone costs around NOK 60,500, roughly NOK 200 per locker, before waste handling and battery logistics are taken into account.

Battery waste is the second burden: single-use alkaline batteries, the type that typically powers battery-operated locker locks, have been classified as hazardous waste in the EU; the requirement applies in the EU from 9 December 2026, and the Norwegian Environment Agency has proposed the same entry into force in Norway. The collection rate for portable batteries in Norway was 63.6 per cent in 2023, according to Norway's official reporting to Eurostat. The rest is never captured by the return system, and some ends up in residual waste — where batteries are a well-known fire source: around 80 per cent of fires at Norwegian waste facilities are caused by batteries, according to figures from the Norwegian Directorate for Civil Protection (DSB) reported by the national broadcaster NRK. With Ojmar's patented Push Power™, neither the battery cost nor the battery waste arises: the energy to read the card and open the lock is harvested from the push of the knob itself.

• Push Power™ — the lock generates its own power: every push of the knob provides the energy to read the card and open the lock, with no batteries and no cables to the lockers
• Maintenance-free — no battery purchases, no battery changes and no service visits to replace batteries over the lock's service life; the whole battery logistics chain disappears
• Zero battery waste — no used batteries to collect or return across the entire service life; the construction is also 100 per cent recyclable and uses half as much plastic as many comparable locks
• OTS 40 Batteryless — the world's first battery-free, cloud-connected locker lock: operated with RFID cards, wristbands or a phone, managed from Ojmar Cloud with a mobile app and an open API, encrypted end to end; winner of the iF Design Award 2025
• OTS 20 Batteryless — the first battery-free electronic locker lock on the market (Best of NeoCon 2024): the same Push Power™ in a standalone system that needs no network, operated with cards, wristbands or key fobs, with an SDK for integration

“This is an environmental problem that can actually be removed — building by building, specification by specification. All it takes is one new word in the next specification: battery-free. The technology exists. From now on, batteries in locker locks are a choice, not a necessity,” says Bjarte Hatlenes, CEO of Focus Security AS.

Ojmar S.A. was founded in 1919 in Elgoibar in the Basque Country, Spain, and is a leading European manufacturer of locking systems for storage lockers — with more than 40 patents, including Push Power™, and certification to ISO 9001, 14001 and 27001. Focus Security is the distributor of Ojmar's electronic locker locks in Norway and is now building a nationwide network of resellers among locksmiths and electrical installers. The locks are built for open integration: Ojmar Cloud has an open API and the standalone locks have an SDK, so the lockers can be integrated into any access control, booking or building management system — open systems without vendor lock-in are at the core of Focus Security. We supply Nedap AEOS ourselves and will integrate the locker locks there; the integration is technically verified and planned.
