Take an oversized piece of plywood. Drill the 2 1/8 hole in the
board. clamp or tack the template to the door and drill away
with the hole saw.

Make sure that the new hole will accommodate the backset
requirements of the strike.

Hello, you put the key in and turn it like normal but the door
won`t "click"
unlock. The house is a raised ranch w/ an attached garage. The
door to the
garage is right next to the main front door and has the same
type of lock so I
just swapped out the two. I didn`t measure the hole where the
knob set goes
into.
Went to the local hardware store and bought two new keyed entry
knob sets.
Had them re-keyed so they could both use the same key. Talked
to a guy at the
hardware store about all the knob sets being standard......asked
if these would
fit in my door and he said yes. Went home to put the new door
knob sets in and
they won`t fit. The existing holes in my doors are too small in
dia. The new
ones need a 2 1/8" hole. How can I drill a bigger hole in the
same place as
the holes I have. I mean it would be easy to drill a hole in a
door that has
no hole. Just use a hole saw......but how to center the 2 1/8"
hole saw in a
hole with no center point. I know you might say .....take them
back and buy
the ones that fit my door hole. I can`t find any that will fit.
The house was
made back in 1963. Buy new doors and drill them......not an
option at this
time for me.
TIA.............for any ideas. Dan.
