Good to keep on hand just in case.
I have this in my go bag ... I have actually had HVAC people show up and were unable to remove the locking cap from the refrigerant port on the AC compressor unit. Told them they do it again I am charging them 200.00 for use of my tools.

Locking cap key/wrench
Locking caps are stupid and just a way that someone is getting rich. Probably multiple someones. No buddy is huffing refrigerant. Oh wow dude that was a knarly huff. I really displaced the oxygen in my lugs, now my brain is suffering and the colors are beautiful. Sorry man not happening! I have accidentally done it and there is 0 high. That being said as a tech i need this stupid key that appears to work fine. And wasn't 30 40 dollars

Good backup tool
Good backup to have as an HVAC tech. The shield key is all I use it for since others always end up breaking on me. Very annoying to have to use daily but can get you out of a pinch when you need it
