How to fit a Yale Cylinder lock in five simple steps
Step 1 - Remove your door handle
Firstly, you will need to remove your door handle. To do this, open your door and unscrew the fixing screws, then pull each side of the handle away from the door and put in a safe place.
Step 2 - Remove the cylinder fixing screw
Next, remove the cylinder fixing screw, which is level with the bottom of your existing cylinder, then insert the key in the cylinder and turn to remove. If you find it difficult, twist the key slightly to align the cam with the door – this will ensure the cylinder slides out with ease.
Step 3 - Measure the size of your existing cylinder
You’ll need to measure the size of your existing cylinder by measuring the length of each half, to the centre of the cam. This will give you two measurements, for example – 60mm and 40mm. It is important to know which measurement is for the external side and which one is for the internal side – as the external side has the protection against attack.
Step 4 - Align the cam with the centre of the cylinder
Once you have your new cylinder, insert the key and align the cam with the centre of the cylinder then place into the lock. Again, you may need to twist the key slightly to ensure the cylinder slots into the lock. It’s important to remember that the AS Series and AS Platinum Series cylinders do have an external side.
Step 5 - Secure your new kitemarked cylinder in place
Next, replace the cylinder screw and screw tightly to secure your new kitemarked cylinder in place. Check the cylinder is fitted correctly by lifting the handle and turning the key. Lastly, replace each side of the handle and fix back into place, then test the operation of the handle together with the lock to check it works correctly.
