Your question: What size hole is a door knob?

Are all door knob holes the same size?

Standard cross bores measure about 1 inch in diameter. The latch bore can be found on the edge of the door, and its standard size is 2 1/8 inches. Also measure the door’s backset, which is the length straight from the middle of the cross bore out to the door’s edge.

Can you use any door knob?

You can typically have multiple entry door locks set (keyed) to work with the same key. However, you may not be able to do this with locks of different brands. Locks with do-it-yourself rekeying let you configure the lock without removing the hardware from the door.

How do you unlock a door knob that has a hole on the side?

When it comes to unlocking a doorknob that has a hole on the side, the solution is simple. Using something small like a paper clip or even a coat hanger, you can insert the tool and move it until it catches. The locking mechanism should release, and you will be able to turn the doorknob once again.
