Master Keyed Systems - Independent Cardiff Locksmith


Master Keyed suits are very common in certain areas as this gives protection between people allocated an area with their own specific lock but gives someone in charge to get access to the whole suite of locks which the master key rules over.  Master keyed locks can be fitted anywhere but are only common on cylinder locks such as the Rim, Euro and Oval Cylinders.


Master Keyed Suites works by having as many locks as you require with each lock having its own personalised keys which don't work on any one of the other locks within the suite but then having a Master Key which will overrule any one of the locks and allow them to Lock and Unlock. Our independent and approved locksmiths Can order these niche locking systems and fully approved and qualified to do so.

James Cardiff Locksmith can talk you through all the requirements and information about these locks. One question which often comes up is that normal locking systems which get fitted do not show being of high quality against attacks and the answer to this is that due to the prices of the systems people often don't like to pay the cost of the more highly rated locks but are very worthwhile if you do decide to have these fitted to a franchise of shops or business' due to the importance and cost of valuable items stored within the building.
