Natalia doors, cupboards, different locks, but always without success.
A bit of a big brain thing here, but if you understand how the locking mechanism work, you don't always have to attack at the locking core to open them.
Additionally, as weird as it sounds, sometimes the easiest solution if you have the time for it is to not even attack it in the first place, but to purchase the key. For any future users who are victims of well, "bad" belts e.g. the following boy from this story:
zbovka I have some unfortunate information deducted from the descriptions of his belt.
It's a cheap Chinese mass produced belt that sells for as cheap as like 22 usd on aliexpress. It's not a neosteel, and their silicone liners always falls off.
The boy's solution, should he ever have the freedom to do online shopping, is to literally find the exact same model of his belt, purchase it, or take a gamble and purchase as many of the cheapest magic key locks and hope he gets the correct one (I know only 2 unique ones so far out of the "proper" uniquely-keyed magic locks). If he does his research, he could probably get out of the belt after spending literally 5 bucks for the 2 types of cheap magic locks, mostly for shipping.
I've never been to wallmart being an aussie, but as another example apparently this used to be one of their products for locksmiths and business owners, a literal keyring set that contains common industrial keys:
The topic of pen testers (short for penetrating testing, or "red team versus blue team", its an actual unique job where a business requiring high security would pay you to test the security of that business complex, take pictures of you being in a place you shouldn't be or less commonly "steal" something before returning it at the end of the day, and write a report on areas they should improve upon, which could be as simple as moving an infrared request-to-exit sensor away from the centre of an entrance)
Although that being said if you're trying to learn to pick so you can pick your own lock eventually, it is an experience worth trying. Unfortunately, many cabinets and cupboard locks work very differently to many padlocks, and depending on what model lock you have, your mother may have possibly paid extra for a different type of lock that may use dimples for example.
