With UPVC and composite doors quickly replacing wood doors as the preferred choice for new home
builders and upgrades I take a look at the most important part of the door – The Cylinder.
Most people don’t realise that the cylinder, the bit you put your key into for those not of a technical
mindset, is the single most important part of your door – it is the part that makes the door
mechanism lock and there are many different types of cylinder on the market.
Some cylinders are considerably better than others, you can pick up a cylinder in Poundland or you
can buy the best on the market – is there a difference? Of course there is, a cheap lock cylinder will
have been made using the cheapest possible metal and will have been made for the lowest cost, the
better cylinders will have been made to a specific standard and will have features to help defeat
So let’s take a look at a standard euro profile cylinder, these are the most common type and found
on most doors in Orpington and Kent.
The picture above is a basic cheap cylinder lock.
This lock will do the job of locking and unlocking the door but not much more – I have been to
several burglaries in Orpington recently where the lock has simply been snapped out of the door
allowing the burglars to enter the property quickly and quietly. This is one of the most common ways
to open UPVC and composite doors and with the cheaper cylinders it is incredibly simple for a
burglar to open your door.
Obviously I can’t show how burglars do this but it is simple and it can be done to almost every
cylinder lock except for a few which have features which I will go into in more detail below.
With most of the doors in Orpington having these locks fitted I am now recommending fitting anti
snap locks as standard.
What is an anti snap lock cylinder?
An anti snap cylinder has been designed to keep burglars out and has features to prevent the lock
being picked, drilled or snapped leaving your home open to burglars.
I recommend as a minimum the Yale Super
