Nintendo’s Parental Controls PIN reset tool will generate a master key to reset the Parental Controls PIN on your Nintendo Switch console. Note: If you need a master key for other Nintendo products, please contact our Customer Service. A Nintendo Account (belonging to a user aged 18+) is required to use the Nintendo Switch Parental Controls app. Linking a Nintendo Account to the Nintendo Switch Parental Controls app allows parents to manage and monitor Nintendo Switch usage through a smart device.

website and type in your inquiry number where is asks for a
confirmation number (they are the same thing) and select the
correct date from the drop-down menu. It will give you a master key
code that you can use for unlocking Parental Controls. This website
also works for the DSi.
NOTE: With the DSi, it can be very hit-and-miss, since there are
reports of it working, and reports of it failing.
mkey is a master key generator for the Parental Controls functionality on various consoles from a certain vendor. Currently, this includes the Wii, DSi, 3DS, Wii U and Switch.
This allows resetting Parental Controls (due to being locked out) without having to contact customer support.

v2 support was initially implemented in October 2015, and has been serving the above page since December 2015. v1 and Wii U support was added in January 2016. v0 support was added in April 2016. v3/Switch support was added in July 2017. v4 support was added in April 2019.
Python and C implementations are available in this repository. These function very similarly.
As of writing, system support is good - all algorithms in use are supported, provided one can extract the necessary keys from the system firmware.
For some algorithm versions (especially 3DS v2) many keys are required from the system firmware in order to generate master keys. These can differ between regions and system versions. The best documentation for these is in the code, which covers the situation on all supported devices.
The v4 algorithm on the Switch and likely any future algorithms also require a console-unique device ID stored on the system that Nintendo can retrieve using the separate, visible serial number one must provide via the support call. The security in this relies upon the device ID being hard to obtain by simply using the device. This would make the generator more of an academic exercise rather than a practical tool.
