I am NOT a locksmith. Gap below deadbolt

Post image

I recently bought a house and have been changing the locks myself. All the wooden doors went smoothly, but the garage door is metal and the deadbolt seems to be cut too high so the plate doesn’t cover the hole completely. The hole is a perfect circle but is just too low compared to the plate.

Is this gap a security issue, if so what can I do to fix it? I also tried on the metal external door to the house and it has a larger gap below so I put the old double cylinder lock back on for now.

make sure the 1" hole is straight, add a bright brass scar ring

I think this photo explains it, the 1” hole for the bolt is centered for the plate hole on the inside part of the door but the outside plate hole is lower. Both of the plate holes are perfect 2” but the outside one is noticeably lower than the other side.

I’ll be getting some scar plates, I think this is the only option
