How do I measure a 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).

Measurement A - Measure from one end of the cylinder to the middle of the central screw hole.

Measurement B - Measure from the other end to the middle of the central screw hole.


Now check your measurements

Measure the overall cylinder length from end to end. The length of the cylinder should equal the sum of measurements (A) and (B) when added together.

For example: If measurement (A) = 45mm and measurement (B) = 50mm the size required would be 45/50 cylinder (95mm in length). No further measurements are required

Please note: These cylinders can be reversed when fitting therefore ordering a 45/50 cylinder is the same as ordering a 50/45 cylinder.


  • 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 offset is protruding from the correct side. Check the operation of the lock before you close the door.


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).


Can I get keys cut locally for Yale cylinders?

Almost all local key cutting shops carry standard Yale key blanks.

What does Anti - Bump mean?


If you have not heard of Lock Bumping before you most certainly will soon, it is now one of the most common means of burglary in the U.K. 'Bump keys' are available to buy on the internet for quite small sums of money and they allow criminals to gain entry into your property without leaving any signs of a crime having been committed. This makes it incredibly difficult to claim for losses on your insurance policies as they usually require proof of forced entry.

There are just nine bump keys that are able to open every kind of cylinder lock on the market today and they are not difficult to make from scratch, we know we tried it.

The Yale branded high security Anti-Bump door cylinder offers a solution to overcome most of the traditional cylinder lock vulnerabilities evident today. This is a high security, British Kitemarked door cylinder lock that works hard to keep your property safe from unwelcome intrusion.
