How do I measure a thumb turn door cylinder?

The size of cylinder you need is determined by the thickness of the door and handle combination,
for this reason there are many sizes available and you will need to be careful that you measure
the cylinder accurately (one size will not fit all). It is possible to measure a door cylinder in the door,
but to be sure it's best to remove it first.

Your new door cylinder should protrude by no more than 5mm from the handle back plates.
It is most sensible to go for exactly the same size as you are replacing (unless your old cylinder was protruding excessively).

It is possible to measure a door cylinder in the door, but to be sure it's best to remove it first.
Measurement A - Measure from Thumb Turn end of the cylinder to the middle of the central screw hole (e.g. 45mm)
Measurement B - Measure from the other end to the middle of the central screw hole (e.g. 50mm).
This would be a 45/50 cylinder (95mm in length). When ordering please remember that the Thumb
Turn will always be on the 'T' side (i.e. 45/50T Thumb turn , thumb turn knob will be on the 50mm side). 

How far should a door cylinder protrude out of the door handle?

Your new door cylinder should protrude between 2mm and 5mm from the handle back plates,
but due to the overall lengths of cylinders available this is not always possible.
It is most sensible to go for exactly the same size as you are replacing (unless your old cylinder was protruding excessively). 

How do I fit a new door cylinder?

These easy to fit replacement cylinders can be fitted by a DIY novice in minutes!
Open the door and unscrew the one fixing screw which is located on the lock
faceplate (the strip of metal the full length of your door), in line with the bottom
of the door cylinder.
Put the key into one side whilst holding the other side firm.
Turn the key and the cylinder should slide out, if it does not turn the key in the
opposite direction and the cylinder should slide out.
Take your new cylinder lock and insert the new key and turn it until the cam is inline
with the body of the cylinder. Insert the new cylinder into position and replace the fixing screw.
If the door cylinder is offset (i.e. 40/60, 30/50 etc) ensure the off set is protruding from the correct side.
Check the operation of the lock before you close the door.
