That’s my point. I do keep buying official TSA locks and they keep being cut off.

Once and only once a few years back YYZ SFO they cut it off and out a gold one back on in its place with the same code. That one then got cut off YYZ LHR last year. On the way back I lost another brand new one.

Maybe I shouldn’t bother! I brought a pack of three last year, have one left.
