Hole in Door for Lock

• The hole in the door must be enlarged to 33 mm (1.3 in.) to fit a new design door lock.
• A template can be made of paper. Make a 1.3 in. circle on the paper and cut out the hole with scissors.
• Use transparent packing tape to fasten the paper on the door.
• Use a grinding wheel on a Dremmel to increase the diameter of the hole.
