Installation Support

To install the Friday Lock you need a screw driver to uninstall your current thumb turn and a hacksaw to shorten the tailpiece if so needed.

You can use a credit card or plastic card to securely release the shell in seconds and get access to the battery. This is used when changing the shell or battery and requires no tools.

The shell of the Friday Lock must be used indoors. The electronics on the interior side of the door must stay dry.

The Friday Lock is installed using your existing lock, making installation easier and safer. Friday Lock is a retrofit to the existing deadbolt lock. Only the thumb latch will need to be changed. The exterior and actual lock cylinder/casing remains. Install the Friday Lock by removing your existing thumb latch and installing the Friday Lock using the same screws and mounting holes.

We’ve put together some videos to help explain how to install your Friday Lock in detail. You can watch the videos if you click on each of the steps shown below.

Step 1. Uninstall old thumb turn, keep the screws.

Step 2. Measure tailpiece with slider. Max length 8mm. Shorten if needed. Or use the Door Adaptor Plate in the bottom of the pack to reduce the length.

Step 3. Rotate the Friday Lock until you find the green and red holes.

Step 4. Screw the Friday Lock with the old screws. If the hole in your door is too big, use the Door Adaptor Plate in the bottom of the pack.

Step 5. Rotate the Friday Lock to desired open and closed orientation and install the tailpiece adaptor.

Step 6. Insert the battery.

Step 3 of the installation requires you to rotate the lock until you find the green and red holes. When you see both, you’ve found the correct position and you can screw the Friday Lock in place. For some locks we’ve got you an image showing the precise position.

In addition, the technology uses proprietary techniques to mitigate false unlocks from the interior side of the door.

Issuing a Remote Key is much like handing over a traditional key except it is handled digitally. Any Friday Lock owner – there can be multiple owners using the same Friday Lock – can issue a Remote Key to other users and adjust the level of access this key will have. As owner, you can set Remote Keys as being time-limited or indefinite, and you can revoke the key at any time. Each Remote Key has a unique signature that is verified between Friday Home and you through a secure and encrypted protocol. When you, another owner or one of your guests access the Friday Home app, the unique key is registered and will show up in the History, allowing you to know who has accessed your Friday Home and when.


If your phone is stolen you can contact Customer Services to disable your phone’s access. Friday Lock recommends that you secure your phone at all times with a code/fingerprint.
