How to look after your Adapta cylinders

23rd July 2017

So you've taken the plunge and decided to buy a Master Key System, fantastic!

Your property is secure and you have one key that allows you to open all your doors! 

This next part is very important though.

Master Keyed Door cylinders have on average, between 24 and 48 moving components on the key side. This means it's very important to ensure the cylinder is maintained on a regular basis to ensure reliability in the future.

The best part is, it's so easy and takes just a few seconds!

We recommend a Silicone or Teflon based lubricant sprayed into the key hole at the following intervals dependent on your environment or usage.

Coastal/Corrosive environments apply MONTHLY.

75-100 key operations a day apply MONTHLY.

50-75 operations a day, apply QUARTERLY.

Less than 50 operations a day, apply every 6 MONTHS.

It really is that easy!

However, under no circumstances use WD40*, Grease or Oil.

Appropriate lubricants and cleaners are available via the Architectural Ironmonger that supplied the suite.

If in any doubt, we're always here to help. Please email us at and quote your Master Key reference number for more information.

*WD40 manufacture a silicone spray which can be used
