The short answer
Access Control Services, explained
Access control replaces mechanical keys with electronic credentials — keypad codes, key cards, fobs or a phone. The practical advantage is revocation: when an employee leaves, you disable their credential in the software instead of rekeying every lock, and you get a log showing who opened which door and when.
Every business hits the same wall eventually. Someone quits, the key doesn’t come back, and rekeying six doors costs more than the key ever did. Multiply that by normal staff turnover and mechanical keys become the most expensive part of your building.
Access control fixes the economics. It also gives you something keys never could: a record. Who opened the back door at 11:40 p.m., which code was used, whether the door was propped. For medical, retail cash handling and anywhere with controlled inventory, that log is worth the install on its own.
