METRA smart high-tech locking system offers the ability to use your lockers for long and short-term use. The system is configured to be self or pre-assigned, by an administrator or the system and opened by a 4-digit PIN, with a phone, RFID card, fob and even your smart watch. METRA electronic locks offer a touch-less experience when using our lockers (versus a battery-operated lock). Combine this with smart integration to your access management system, for a secure and seamless user experience for gym members and patrons. Our smart locking technology is reliable, secure, and user-friendly. It allows you to feel that you — and the things you need daily — are safe, secure and are cared for.
