Removing/refitting Euro cylinder:

Although the section of euro cylinders are standard, the length of the cylinder and the offsets about the locating screw hole do vary, so it will probably be necessary to first remove the existing cylinder from the door to measure it, refit it while you purchase a replacement, and then go through the removal/replacement procedure again - don't worry, it only requires removing one screw.

Proceed as follows:-

  1. Unlock and open the door.
  2. Locate on the edge of the door the cylinder fixing screw, (normally a large headed screw inline with the lower end of the cylinder) remove the screw.
  3. Next turn the key in the cylinder to bring the cam in line with the body of the cylinder so that it can be withdrawn - the cam is hidden in the door so this has to be judged by feel - it is normally about 25° off of the unlocked key removal position it may be clockwise rather than anticlockwise. (Note: If the cylinder fitted has a Thumb Turn knob, there is no need to use a key, just turn the knob to align the cam.)
  4. Slide out the door cylinder to the key (or Thumb Turn knob) side. If the cylinder catches, try turning the key to about 25° on the other side of the key withdrawal position. If the cylinder will not slide out of the door, it may be that it is being snagged by the door furniture or the locking mechanism. In this event, the door furniture and/or the locking mechanism may need to be loosened so that the cylinder is free to slide out.
  5. Measure and note the 2 offset dimensions from the fixing screws (see illustration) - if the offsets are different, note which side of the door each offset applies to.
  6. If necessary, refit the cylinder in the door until a replacement is purchased - the procedure is just the reverse of removal but the cam can be aligned with the door cylinder by eye.

Purchasing a replacement cylinder:

Purchase a replacement euro cylinder having the same offsets as the original - if a Thumb Turn type is to be fitted in place of a double key type (or vice-versa), the offsets still need to be the same as the original. Remember to have any extra keys cut at the time of purchase.
