Troubleshooting resource
When an access card or fob stops working, first establish whether the problem follows one credential, one door or the whole site. Protect required egress, preserve the event time and avoid repeated guesses or resets that can hide the cause.
Identify the diagnostic pattern
- Does the reader react at all?
- Does the credential fail at one door or every door?
- Do other current credentials work at the same opening?
- What event or denial reason appears at the same time?
For Card Not Working, these observations help distinguish a permission decision from a reader, controller, power, network or mechanical fault. Record facts before changing anything; an undocumented reset can remove useful evidence.
Safe checks for an authorised site contact
- Check the user has the correct credential and door
- Confirm the intended access time and area with an authorised administrator
- Try another known-current credential only if site procedure permits
- Report a lost, damaged or replaced credential promptly
For Card Not Working, stop if the opening affects emergency egress, becomes hot, produces an electrical smell, cannot be secured or requires an enclosure to be opened. Use the site’s emergency and service escalation process.
What a technician may investigate
- Credential status and format
- User access groups and schedules
- Reader communications and controller events
- Whether card technology or encoding matches the reader
For Card Not Working, electrical measurements, enclosure access, wiring changes and safety-interface tests should be performed only by appropriately authorised and qualified people under controlled site conditions.
Reduce repeat faults
- Issue credentials to named users
- Record replacements and disable the old credential
- Review dormant and expired users
- Keep reader and door identifiers clear in event reports
Information to send with a service request
| Record | Useful detail |
|---|---|
| Opening | Site, door name or number and entry or exit side |
| Time | Exact time, duration and whether the fault is intermittent |
| User action | Credential type or authorised action without disclosing a PIN |
| System evidence | Reader indication, event message, controller or panel state |
| Recent change | Power, network, building, door, user or configuration work |
| Safety state | Whether normal exit and secure closure remain available |
Card Not Working questions
Can the door remain in service while card not working is investigated?
For Card Not Working, only if required egress and secure operation remain available and the organisation’s responsible person accepts the temporary condition. Escalate unsafe or unsecured openings immediately.
What evidence helps diagnose card not working?
For Card Not Working, provide the site and door identifier, exact time, user action, reader or panel indication, event message, recent changes and whether the symptom is intermittent.
Should an authorised user reset the system after card not working?
For Card Not Working, not unless the approved site procedure calls for it. A reset or power cycle may remove evidence, interrupt other doors or conceal a power, network or hardware fault.
When does card not working require urgent escalation?
For Card Not Working, escalate impaired egress, overheating, electrical smell, smoke, damaged wiring, failed emergency release, uncontrolled unlocking or a door that cannot be secured.
How can card not working be prevented from recurring?
For Card Not Working, use the page-specific preventive checks, keep door and device records current, investigate repeated events and include the relevant hardware, power and administration in planned maintenance.
