RIM Installation Instructions

Prepare Nexkey Core - If you are replacing a cylinder, be sure to note the length of the old tailpiece. When installing outdoors, be sure to install provided O-rings to prevent water incursion

Remove Mechanical Cylinder - Remove the existing RIM hardware to gain access to the two RIM cylinder retaining screws. Loosen the retaining screws and remove the RIM cylinder and RIM cylinder retaining plate from the door.

Install Nexkey Core into Lockset - Select the cylinder ring that will position the cylinder to the correct length. Make sure the tailpiece has been measured and cut to the appropriate length, then break off the screws so the clamp plate and cylinder properly tighten onto the door.

Unlocking the Nexkey Core

Step 1

Open Nexkey App, tap the front of the Core , and It will start to blink blue.

Step 2

Once the Core LED turns solid blue, then you can twist as you would a key. The resistance and turn will be the same as with the lock’s original key.

What does the LEDs mean?

Slow Blink: Device is attempting to connect to the Nexkey app

Fast Blink: Device found, Authentication in process

Solid LED: Core unlocked

Solid LED for longer than 10 seconds: Device needs to be power cycled by removing and reinserting the battery.

Testing Nexkey Core

The Core should not change the function of the lock. The lock should operate in the same manner as it did with a key.

Step 1

Keeping the door open, open the app and tap the front of the Core. The LED will start to blink, when it turns solid you should be able to rotate the Core and unlock the door.

Step 2

Once you have gained confidence in the lock operation, close and lock the door. Test the Core.

Step 3

You may be able to turn the Core but the door should not unlock when the LED is off

  • The battery can be replaced from directly from the front side of the lock.

  • Power cycle the Core by removing the battery for 20 seconds and reinstalling.
