Well in my opinion because since you have the power you are not using to wear a chastity belt. Basically, further the physical use the chastity belt means to be overpowered. And you do not know this intense feeling if you have a key. You can not know what means wear a belt if you have power over your belt.
Your situation is hard, in fact I do not trust in your mother in this sense, but, this point that I am touching is true, and every girl here can say you the same.
Reasons a chastity belt sucks?
Ines Well in my opinion because since you have the power you are not using to wear a chastity belt.
I agree with you, but I think in such an awkward situation they should move forward very slowly.
- - Get used to wearing the belt.
- - Build loving trust with keyholders.
- - Gently experiment with not having the key.
- - Choose whether to keep the belt or dump it.
In this manner consent is assured and all parties end up getting a fair chance of getting what they want - in the end.
Jonas Could they not give up the key to enable the belt to be trialled?
She can ask to be unlocked anytime instead
Ines I believe the same, and it is pretty logical, I would not give the key to the wearer.
My parents do the same. They never give me the key
Jen they can trust me first by handing over the key
They can trust you be leaving the belt open
A negative reason I'm surprised isn't listed yet:
You can't hug your friends without risking some questioning looks.

Even with vaccine social distance must be maintained.
And with my chastity belt I hug friends and relatives... I do not brush my body when I hug someone! And I am southern!
Even with wide belts over the drees more discreet. There are a lot of propaganda and with a chastity belt you can wear trousers without problem.

@catherine98 mentioned it
Jonas The submission occurs at the outset in such a case.
Every CB wearer is more or less submissive
Jonas As I say, I think copying the key isn't an issue because a replacement lock/key can be bought if and when they're needed.
right, if it should really become serious, the padlock can still be changed afterwards
Jonas - Build loving trust with keyholders.
and this is exactly where I do not see @Jen at the moment.
gwen You can't hug your friends without risking some questioning looks.
I have always hugged my friends, you just have to make sure you do it in the right places. 
Angelina right, if it should really become serious, the padlock can still be changed afterwards
Exactly.
To break the current impasse, Jen could respect her parents feelings by going through with the agreement to try the belt, and her parents could demonstrate that they respect her feelings by offering up the key to begin with.
You could make a lot of those complaints about wearing clothes generally :l The only difference is that clothes are socially acceptably and a belt isn't.

that would be a solution, but only in a perfect family and @Jen's mother has not proven to be very trustworthy.

I've been thinking again about this, and looking again at what Laura said:
Laura She can ask to be unlocked anytime instead
Though the belt was presented in a very negative and stressful way, I don't think these parents would go against their previous agreement to remove the belt whenever asked (during a trial period), and anyway, Jen has already won the battle to make her own choice as to whether to wear the belt in the long term. So the initial submission here isn't a huge one.
I still think the 3 day trial isn't sensible - better to take things much more slowly, a couple of hours a day with regular unlockings, to check fit and soreness, but also build trust and confidence. I think her parents would be happy for her to try it at this point and would work to ensure that things went smoothly. But who knows eh? We have too little information to do anything more than speculate. I just hope it all works out well for all concerned.
Jonas
Why should @Jen take the risk when it is safer to try the CB independently of the parents?
First, she wants to find out what it is like to wear it for longer. It may well be that she has had enough after the first time and wants to leave it at that.
If she wants to go further, she can always think about how it can be safest for her. Several options have been listed so that "all or nothing" is not necessary

I definitely still think she could ask for the key and do the trials for herself as I suggested above. However, looking back, I think that with the help of good advice on here, she's already established that they cannot force her to wear it, (what would friends/family say? etc), so the risk is negligible, the only concern here is avoiding further bad feeling. Ironically, going through with the original agreement might help to address just that.
First, she wants to find out what it is like to wear it for longer. It may well be that she has had enough after the first time and wants to leave it at that.
As I understand it, the deal was that belt could be removed for any reason during the trial period.
Overall, it kinda depends on her motivation. If she's seriously considering chastity then Ines is right, it's not a fair test of if you have the key in your possession. Further, if the belt is just being considered for use as a toy then it might be kinda unfair on the parents to demand the key.
If however, she is simply attempting to keep to the previous agreement, or remains generally unsure about the whole idea, then the parents could help this by supplying the key for the trial period.
