Automatic doors: installation, repair and servicing

Automatic doors. Working with the systems around them.

We install, repair and service automatic doors at the entrances of residential blocks and commercial buildings across London within the M25.

Because we also install access control and door entry, your automatic doors can open from a fob, a keypad or the door entry panel, all handled by one team.

What we do. Install, repair, maintain, connect.

New automatic door installations

Repairs to existing automatic doors
Fault-finding and repairs on most makes of operator, sensor and control, including doors we didn’t install.
Servicing and maintenance
Planned maintenance visits that keep doors safe, reliable and compliant, with a clear report provided after every visit.
Linking doors to access control and door entry
Doors that open from a fob, keypad or door entry panel, set up and supported by one team, so there’s no back-and-forth between suppliers.

Why AB Key. One contractor for the whole entrance.

Automatic doors rarely work alone; they’re connected to access control, door entry and fire alarm release. Because we install and maintain all of these, one team takes responsibility when an issue arises.

Safety and compliance.

Powered pedestrian doors must be safe for everyone who uses them. Our maintenance visits check safety sensors, force and speed settings, emergency release and fail-safe operation, in line with BS EN 16005. Regular servicing also supports your duties under the Equality Act by keeping accessible entrances working.

Planned maintenance contracts.

Most door faults are preventable. A planned maintenance contract gives you scheduled visits, priority call-outs and a full service history for every door across your portfolio, so you have the records when you need them.
