Ham fisted users are going to have problems
I've bent my key a bit multiple times. I know exactly how soft it is because I've straightened it multiple times. Now, I know you're thinking I'm a ham-fisted *******, but that dog won't hunt. I have over 50 years experience passing mechanical aptitude tests, including building and flying a complex aircraft. I have a car hoist in my garage and haven't paid anyone to work on any of my vehicles since I was 18. About 5 years ago I relented and started paying for tire mouting, but only on my cars, not on the bike or the skidsteer or the dump truck. I tell you all that to assure you that relieving the strain on a latch before turning a key comes as naturally to me as taking a leak after drinking beer. I take from the comments that some keys are softer than others. Water remains wet.
