Figure out your cylinder number

After you measure your cylinder number, you will find out the diameter of the interior and exterior length of your cylinder. For example, your cylinder has an interior length of 35 mm and an exterior length of 55 mm. It means you need a new cylinder with 35/55 size and in 90 mm length.

Buy the cylinder

You have measured your cylinder and based on the measurement, you now have your cylinder size. The next step is to purchase the new cylinder. You can buy new cylinders with appropriate keys from trusted locksmiths or online security shops. Here are some terms to think about upon buying a new cylinder:

  • Digital/mechanical
  • Digital cylinder means you change your traditional keys with digital keys. This can mean a PIN-code, an RFID lock, or making your smartphone as the lock. A mechanical cylinder means a manual cylinder which needs a key to be operated.

  • Knob
  • A knob cylinder means that it has one cylinder on one side and a knob on the other side. People use knob cylinders mostly for front doors with the key facing the front side and the knob facing the inner side.

  • One-sided or double-sided
  • One-sided cylinder means a cylinder with only one keyhole. Think of a cylinder for storage room. Meanwhile, double-sided cylinder means that both ends of the cylinder have keyholes.

  • Cylinder with panic function.
  • If you put this kind of cylinder on a door, you can open the door even if the key is still latched on the keyhole.

  • More than one-solution cylinders
  • Do you have a lot of rooms and you would like to have only one key to secure them all? Keyed alike is the key (pun intended)! With this system, you can create your customised locking plan, so you can access different doors with only one key.

In conclusion, changing the cylinder to your door is something that you can do yourself. You can save a lot of money by keeping the matter on to your own hands and not calling the locksmith to change them.
