Types of System We Maintain & Service
We maintain every type of access control, from simple standalone readers to complex networked systems.
Key Card or Fob Access Systems
The most common system. We clean readers, test range, check programming, and make sure all cards work. Regular maintenance stops the annoying ‘card not read’ problem that wastes everyone’s time.
Mobile Entry Systems
Smartphone credentials and fingerprint readers need careful maintenance. We update apps, check connectivity, and ensure backup access methods work. Modern tech needs modern maintenance.
Keypad / PIN Code Entry Systems
Simple but effective when maintained properly. We check buttons still work, update codes regularly, verify weather sealing, and ensure keypads stay readable. Regular code changes keep these systems secure.
Intercom & / Video Entry Systems
Audio and video entry systems for visitor management. We test cameras, clean lenses, check speakers, and verify door release mechanisms. Clear communication and reliable operation when you need to screen visitors.
Visitor & Temporary Passes
Systems that issue temporary credentials need regular attention. We update software, audit active passes, and ensure expired credentials are properly revoked. Secure visitor access without permanent risk.
Included in Our Access Control Maintenance Packages
Every visit covers everything. No hidden extras, no “that’s not included” surprises.
Device-Level Servicing
We don’t just check the main panel – we test every reader, lock, and exit button. Each device cleaned, tested, and verified. Problems found early before they cause lockouts.
Thorough Logging of All Details
Everything is documented in an online portal for easy reference. Which devices were tested, what was found, what was fixed. Full audit trail for compliance and insurance. No more hunting for paperwork during inspections.

FAQs
Quick answers to common questions about access control system maintenance.
Why is regular access control system maintenance important?
Without maintenance, readers fail, locks jam, and security weakens. Regular servicing prevents lockouts, maintains security, and ensures emergency releases work. It also keeps user lists current – essential for real security.
What is included in an access control system health check?
We check every reader, lock, and exit button. Test backup power and emergency releases. Verify user permissions are correct. Update software and firmware. Clean all devices. Document everything in an online portal for your reference.
Can you upgrade my current access control system?
Yes. We can add mobile credentials to card systems, integrate with other security, or add new features. Sometimes we replace controllers but keep locks. We’ll assess your system and explain what’s possible.
Do you offer support for systems installed by other providers?
Yes. We take over maintenance of any access control system. Doesn’t matter who installed it – we’ll fix it, and maintain it properly. Many customers come to us after poor service elsewhere. We audit the system and bring it up to standard.
What benefits do I get with remote troubleshooting?
Faster fixes without waiting for engineers. We can check your system, identify faults, reset controllers, and update settings remotely, solving problems in minutes instead of hours. You get less disruption, lower costs, and better security.
