1. Remove the old cylinder

First, you have to remove your current cylinder. Unscrew the lock screw in the mortise plate on the side of the door.

2. Pull out the old cylinder

Insert your key and turn it so the cam lines up with the body of the cylinder. Now pull out the cylinder. 

3. Adjust the new cylinder

Measure the back part (on the outside of your door) of the old cylinder from the middle of the screw-hole and away (see illustration). In the Danalock box, you’ll find an adjustable lock cylinder.
If the old cylinder and the adjustable cylinder match - go to no 5. If they don’t please proceed.

4. Unscrew the small screws on both sides of the cylinder and pull it apart.

5. Insert the same size of spacer piece and brass tube to make the adjustable cylinder match the old cylinder. Please look at the following size guide to find the right length for the spacer piece and the brass tube.

Size guide - When you adjust the size of the Danalock cylinder to the old cylinder you‘ll have to exchange the brass tube in the center with another that fits the spacer piece. Here are the different combinations.

6. Assemble the cylinder and screw the small screws back in on both sides of the cylinder.

7. Insert the adjustable cylinder

Insert the new cylinder, and re-insert the lock-screw in the mortise-plate to fix the cylinder. (b) Do not tighten the screw to hard - make sure the cylinder is working by locking and unlocking with your hand.

8. The right rosette spacer

To avoid pulling the cylinder out of place you need to find the right spacer or a spacer combination between the rosette and the back plate. Unscrew the two breakable screws that holds the spacers together with the adjustable cylinder. Choose one or more spacers so they flush with the rosette surface. (See next illustration).

IMPORTANT! Avoid pulling the cylinder out of place. It is important that the spacer flushes or sticks out from the hole in the rosette plate.

9. Break the screws to the right length

Depending on which spacer or spacer combination you chose, it is now important that the screws that fasten the cylinder to the backplate have the right length. Use this chart to find the right length. Use a wirecutter, two pliers, or bend the screws forth and back several times in a vice to break them.

10. Fasten the backplate to the cylinder

Now fasten the backplate to the cylinder with the rosette spacer in between them.


IMPORTANT! Check that the lock still works!

Make sure that the lock still works properly by tuning the tailpiece. If you cant lock and unlock this way please loosen the cylinder screws.

11. Give the tailpiece the right length

To avoid damaging the Danalock you will have to shorten the new cylinder tailpiece to a max of 35mm from the door surface. Use two pliers or a wire cutter to shorten the tailpiece.

12. Attach the tailpiece adaptor

Insert the green tailpiece adaptor in the center tube on the backside of the Danalock. Press on the adaptor until a click ensuring it is fixed firmly to the Danalock.

13. Fit the tailpiece to the middle of the housing base

Fit the Danalock over the backplate. Make sure the tailpiece hits the slide in the middle of the adaptor.

14. Align the plate marks

Find the small marking on the edge of the backplate and align the mark on the back of the Danalock baseplate with it. Now you are sure to hit the notches on the backplate with the Danalock.

15. Fasten the Danalock

Turn the Danalock clockwise until it clicks to fasten it to the backplate. NOTE: If you need to unfasten and retry, see “Uninstall instructions” at the end of the manual.

16. Activate batteries

Pull out the plastic tab to activate the batteries. Alight will flash to confirm the Danalock is ready.

Dismount instruction

If at any time you need to dismount the Danalock from your door, insert a pen tip into the hole at the top inner edge of the lock and press while turning the lock counter-clockwise until the lock releases. This will not reset the lock or disconnect it from your account, but the lock may need to be re-calibrated if fastened to your door again.
