E.g. hidden backdoors for government agencies.
They certainly do it with consumer level encryption methods, is it similar with high security non-military locks?
While I suppose anything's possible, I'd find it highly unlikely.
Installing a hidden security hole in a crypto system (built upon many thousand lines of code and advanced mathemetical theory) is one thing (and, as you point out, has been done in some cases in the past). Hiding a secret backdoor in an easily-examined device with 20 or 30 parts, though, is very much harder. With the amount of effort that is spent examining locks by people on this site, I am sure that some evidence of "backdoor" engineering would have shown up if it were there.
