the lock!
Vanessa I meant the consequences for convinced wearer would only be to lose the advantages they get,and that the fact they lose these,and resume with the rules they had before,would be enough to make them keep wearing it.
that's true, there is a certain difference to us involuntary wearers. sounds a bit like oprant conditioning. using negative/positive reinforcement/punishment, i read something about that in a book recently.
Tollyboy locks are mostly 7 pin radial locks there are some 8 pin radial locks, there is one 13 pin radial lock where the pins are set in a double row with cuts on the inside and out side of the key.
On many of them a radial pick will certainly not work easily as the bottom pins are of variable length and the springs are of differing strengths so just bottoming out the tool will mostly not work.
Most locks have a spool pin(s) and/or serrated pin(s) to give a false set.
Some special locks also have trap pins in them. Try to pick one of them and don't get it exactly right and you will have a lock that can't be turned by anything including the original keys.
There are some odd ball belts out there with very bulky Medico locks, I wouldn't think they would be pickable even by most locksmiths.
There is / was some experimental work with Galaxy locks from the Australian lock company. I think they are practically unpickable by anyone.
In theory yes it is but some Tollyboy locks have some very nasty surprises in them.
The bottom pins are not always all the same length and with different strength bottom springs it makes finding the shear line of the lock harder.
Most perhaps all locks contain spool pin(s) when picking these give a false set. They feel like they are in the right shear plane but instead you have caught the edge of the spool instead of depressing it to the shear plane.
Serrated pins have grooves turned on the outside which also feel as if they are set at the shear line when they are not not.
Some locks contain trap pins These are really nasty the bottom pin in the lock is made in two pieces the bottom part of it hollow. It is possible to pick this lock in two positions the correct one where the bottom pin acts like a normal solid pin and the wrong one where the lock turns with the exposed top of the hollow pin in contact with the turning portion of the lock. If this happens then the lock will turn a certain distance until the top of the hollow pin meets a circular groove when the spring will push it into place locking the lock permanently against further turning. At this point the lock is dead. Nothing will turn it either way not even the original keys.
If you decide to pick it you are gambling that either you are very good at picking or that there are no trap pins in that lock. A trap pin variant looks exactly the same as any other 7 pin radial.
Dilly I would recommend 3D scanners and 3D printing, if it has key it's possible to copy it 
hornyaspie2 How many wearing a chastity belt, have the key + 3D scanner and 3D printer? 
If you have access to the key, why not open the belt, instead of using 3D?

well, that sounds more a scary movie, I don't doubt they exist for specific purposes, but a CB manufacturer using something like that to get stuck people in their belts and finish being news in the newspaper because somebody without DIY abilities nor radial cutter called firefighters to cut a CB?

True but maybe not as helpful as you would hope.
Tollyboy did offer permanent locks. These look normal, have a key but will only turn clockwise. They are literally use once and the key is thereafter useless.
Many lock makers also sell change key locks, these have two keys one that unlocks it and one that won't unlock it but will change the internal pinning so the first key will no longer work. Normally you buy these with a set of 7 keys plus the change key so when the key gets lost of compromised you can change the lock and use a new key. These would be very effective on a belt as you could lock the belt then change the lock so even if the wearer got access to the key it wouldn't work.

3D printer service are become more and more common it's usually located near Technical Universities and Colleges even some good equipped schools have it , 3D scanner could be rented or use phone with good quality camera instead

Again another fancy story, for CB use I mean, that has no sense, the key becames useless, no longer needed to keep, and anybody could "steal" the latest key version.
That just make sense for locks which needs the key for locking (radials), allow anyone to lock, and then not to unlock, but again, with special key that should have the "first locker"?
and also taking in account this can be only done once...
hornyaspie2 I think you do not really understand how a key holder stores the chastity keys.
Taking the key to go to a place that has 3D equipment becomes more a fantasy and a dream than a reality.

I wanted to help, fortunately it does not apply to me, but I am interested in this technology, because I have Asperger and ADHD, it is 3D printing and not chastity belts: D
This is a bit of an interesting but as a game an interesting BSDM game :-)
There us always, nuclear option always remains to notify the cops, the only right one in my opinion in the cases described above

That silly so how to unlock it when it really needed?

Sorry I didn't explain change key locks well.
A change key lock usually has 7 numbers engraved on the front of it 1-7 or 0-6 depends on who makes them.
They could be bought with any number from 1 to 7 of different keys and a change key.
Assume we only have key No 1 and the change key.
To use the lock you insert the change key and turn it to position No 1. The lock will now work like a perfectly normal lock with key No 1. If you now use the change key again and turn the lock to any or the other 6 positions key No 1 will no longer work in this lock. As soon as you reset it to one key No 1 will work again.
The reason these sort of locks could be useful on a belt is that both parents can hold a key and the lock can only be opened by both of them together, first the change key then the unlocking key.
There may be reasons to have several people with permission to unlock the belt. It is perhaps possible that the wearer may be going to stay long term with another relative and the belt could be programmed to their key before departure.
