NEVER insert a changing tool
"NEVER insert a changing tool into the lock unless the lock's cover is in place."
So goes the typical warning. But, why? I understand that even a slight angle will affect the true dialing numbers, but is there something more damaging than that to consider?
I have practice locks with the back covers off. I mount them this way because I cut my spindle to length for four wheel locks so I can use one dial for all the locks. I've been changing the combinations without the covers in place, taking care that it is fully inserted at the right position with the tip in the pivot hole, and I hold it as straight as I can. So far, no problems, but I thought I'd pose this here in case I'm missing something.
