When an access control system goes wrong, door held open all night, reader unresponsive, controller offline, software refusing logins, mag lock dropped because of a tripped supply, SEG Ltd attends fast and fixes properly. We work on every major manufacturer: Paxton Net2 and Paxton10, Salto, ACT, Inner Range, Honeywell, Suprema, plus a long list of legacy standalone units. The first thing we'll do on the phone is try to narrow the fault: many issues are resolved with a quick reset, a credentials re-pair, or a software user fix without anyone needing to attend site.

Common faults we repair include power-supply failure on a controller or mag lock (often the obvious symptom: the door has stopped securing), reader read failures (could be the credential, the reader, or the wiring), controller comms loss (DHCP, switch, or controller itself), software user/permission issues, REX (request-to-exit) sensors stuck open, door closers no longer self-closing, push-to-exit buttons mechanically failed, and broken break-glass overrides. Most of these are repairable in a single visit; a few need parts ordered and a second visit, in which case we propose interim safety arrangements (locked override, manual key control) until the fix lands.

Our diagnostic visit fee covers attendance and fault identification. If the repair can be completed in the same visit you only pay for parts plus the additional time. If a component is at end-of-life or no longer manufactured we'll quote a like-for-like or upgrade path, and credit the diagnostic fee against the replacement. No "while-you're-here" upsells.
