Maybe you need to find another carpenter?

Tell us the type hardware you purchased

" two regular hollow slab doors"
Slab doors are not drilled for lock-sets.

What is the problem?

If he drilled the doors incorrectly he replaces them.

You do not drill slab doors without the lock-set template IN HAND (even if you do not actually use it).

Hello All - I picked the doors, not knowing the difference. The doors had the holes already in them. My carpenter assumed I knew what I was doing :) . I'm looking at Kwikset Models # 335 15 (Privacy) and 334 15 (Passage). These two are for a 2 3/8 backset, not the 2 3/4 backset I require. Thanks All!

Now that I am thinking about it you will need to replace the door as it is only available with a 2 3/8" backset.

So, your "carpenter" says, I'll just use a hole saw with my lock jig, redrill the door for a 2-3/8 back-set, remove a portion of the door skin from each side of the 1/4 moon cutout, glue, fill, sand, prime and paint it on the backside of the 2-3/4 hole and install your lock-sets".
OR, you can, again pay this same "wise and seasoned" carpenter to hang and paint new doors.

If the doors are to be painted it is not all that hard to plug the existing hole and then move it to the required back set. It just takes time.

A hole saw to cut a plug, some Minwax High Performance Filler to attach the plug in the old hole and smooth out the surface on both sides, then bore a new hole.

The existing hole is trough internal blocking in the door already.

It may well cost as much as a 'commodity quality' hollow core door though.

Labor hours are expensive.
Buying materials without a complete knowledge of nomenclature and use often results in the wrong item being purchased.

You might have been able to swap the doors for true slab doors if they had not been modified in any way not a single screw hole, brand new condition).
