What do do when your intercom system needs servicing

One day, out of the blue, a door entry system can start causing trouble: the video doesn’t work, the buzzer no longer makes a sound etc.

At Metrolocks, we have all the expertise to conduct intercom system servicing and maintenance for you and your building.

Get in touch with us, explain your entry phone’s symptoms, and we will advise you on what steps to take.

Our expert team covers the entire Greater London area.

With over 25 years of experience in London-wide door entry system maintenance and installation, we at Metrolocks are perfectly placed to help you out, whether the issue is great or small. Most importantly, our prices are competitive, and we always quote for works in advance.

If you’ve ever had an intercom system in a flat, you’ll never again want to be without one.

Tell us about your intercom troubles, and we'll set them right.

How do I describe my intercom problem?

There are a number of common symptoms that arise in door entry systems. It’s not always simple to identify the underlying issue, but understanding the symptoms helps us to help you.

Audio or video not working inside your flat

Door release button inside the flat does not release the door

Doorbell button on exterior panel not ringing within the flat

Door is always open, whether you press the door release or not

Through fault-finding, we at Metrolocks can identify the cause of the problem and make the necessary repairs, to ensure that all door functionality is as it should be: perfect.

(We’ve got a blog post about how further to diagnose your intercom system, which can be found here.)

Some of the brands we service

Here are a few brands that we come across on a regular basis. In most cases, the brand name will be written on the intercom panel outside the building or intercom handset in your flat/office. If you can’t see a brand name marked on the panel, not to worry. Send us a few pictures and we’ll be able to identify it.

Above all, don’t worry if you’re not really sure how to describe the intercom. We’ll be able to ask all the right questions, thereby making the diagnostic process much easier.
