Emergency key
There are not many emergencies I can imagine where it is necessary to remove the belt.
If they must, put you in an MRI scanner or insert a catheter into you in the ICU.
You must always have a key with you, but it must be impossible for you to use it.
Otherwise, the whole idea of a locked belt is pointless.
I have my emergency key fixed with a cable tie to this metal triangle on my back.
With a mirror and scissors, I can't get it, so it's a safe place for "horny" moments.
In my opinion, the safest way to open a cb without a suitable key is to pick the lock. Appropriate tools are available on Amazon and instruction videos elsewhere.
A good cb is made of stainless steel. This means that you have to use massive force to destroy it. This is simply too dangerous for the wearer. Also to destroy the lock requires some force. At least if the bracket is protected accordingly.
Except magnetic locks, I know of none for a cb that can not be picked.
Well, a paper clip is not a suitable tool either.
I think we should get back to the topic of emergancy key. For lock picking there is another thread.
That was probably a bit misleading on my part. Lock picking is not an emergency key for me. Only of the methods that have been discussed, it is the one that is the least dangerous for the wearer.
