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.
