What to replace old deadbolt on our front door.

Old deadbolt 1 3/4" lock with 7/8" bolt.

New deadbolt 2 1/8"wit 1" bolt.

For the new lock (deadbolt) hole I'm thinking of making a template out of 1/2" scrap wood, hole-saw a 2 1/8 hole, center it over the 1 3/4" hole, clamp then drill it out to enlarge the hole.

Now enlarging the 7/8" to a 1" bolt might be a little tricky, should I buy a gouge chisel and try to enlarge it that way? Or go with another template? But how to clamp the template to the edge of the door (don't have any pipe clamps), I suppose I could drill two holes and wood screw it into the end of the door to hold it in place? (kinda hate to add two new hole for the screws)

Thanks in advance!
