Thumbturn adapter for Switchbot Lock Ultra

This is an adapter insert for the Switchbot Lock Ultra that allows the use of a Euro lock cylinder with thumbturn, where the thumbturn knob is not removable. It will be necessary to file out the mounting plate to provide enough room for the thumbturn to pass through. If you're careful with this, you can still use the templated parts of the mounting plate to ensure you're mounting in the right position. If you have a thumbturn Euro lock like you'd find on Amazon, this adapter might do the trick for you. Just alter the mounting plate as said, remove the 2 screws holding the official insert in place, replace the insert and reinstall the screws and you're good to go!
