Are additional M1 cards available for sale?

our M1 cards is not available currently, but you can find others', as long as the frequency is 13.56MHZ, it will work with our lock

can this product be used on a multi point lock?

Yes it can, but be prepared for a fair bit of work to make this happen. The handles and lock supplied have centres of 85mm but nearly all British Multi Locks are 92mm centres. After discarding the mortise lock supplied you will have to change the handle centres by removing the barrel carrier and lowering it by 7mm, this will require some of the carrier to be filed away and the retaining screws replaced just retaining the edge of the carrier (not through the holes). Then file to adjust the faceplates. Purchase a 92mm multipoint and fit with the altered handles. The lock will work ok. Just completed this and all functions good.

how are the pin codes be generated or revoked? I want to use this lock for a bnb property.

There is no APP you have to change via the keypad directly
