Choosing

Which smart lock fits my door?

Published on October 11, 2026

Choosing a smart lock does not start with the lock, but with your door. Do you want to replace the cylinder, or rather not? And who needs to get in?

Five locks, five situations

  • You replace the cylinder

    The Core takes the place of your current cylinder, made to measure for your door. You open with your phone or a card.

  • You want to get in without a phone

    The Core Touch has keys and a fingerprint reader on the outside knob. Handy for children and guests.

  • Your cylinder has to stay

    The Motion goes on the inside over your existing cylinder. From outside your key still works.

  • It is an interior door

    The Handle is lock and handle in one, for doors 35 to 55 mm thick. You open with your finger, a code or a card.

  • You do not want to touch your lock

    Your ordinary key sits in the Keybox. Whoever needs it opens the box with a code, a card or a finger.

If you choose a cylinder you need two sizes: from the screw to the outside of the fitting, outside and inside. This is what a 46 and 61 mm cylinder looks like:
