It seems like what they want is not so much breakable locks, but for you to have locks that can all be opened by a common master key. And they pinky swear that the master key will be kept totally safe and all the thousands of law enforcement officers they share it with will also keep it totally safe, and they will never ever use it except for intended purposes, and no bad guys will ever be able to get a copy of it.

This is the Common Master Key (CMK) theory. How are they going to keep CMK secret (using encryption? which encryption?) and they can make sure the holders of CMK are honest (that they can't be forced/bribed/etc.) about their usage?

I wouldn't trust my government with these keys.

The point is we couldn't trust anyone with that kind of a key; it's fundamentally unsafe.

Fun fact, they did this with luggage locks. Long story short, TSA master keys are readily available on the internet.
