I believe some condensation got on the L key of my keyboard. It no longer functions at all. In system preferences, only special characters can be remapped. I was wondering if anyone knew of any third-party app that would allow me to re-map one of those rarely used characters to act as the “L” key. I purchased an OEM replacement keyboard, but after watching the instructional videos, I’m not too keen on spending four hours on the repair, and I am definitely not taking it to a place that is going to charge me $300-$400. But it is also extremely inconvenient to use the on screen keyboard for one of the most common letters, and even more inconvenient to carry an external keyboard around with a laptop. Aside from that, the computer is perfect and has just been upgraded to the max.

Nobody doing repairs would ask 3/400$ for a keyboard replacement. Ask around, you’ll probably get it done with a 100$, it’s a boring and time consuming headache turning a screwdriver for a couple of hours, but nothing complicated unless one does some noob silly mistakes. However, if you like better the idea of remapping the key, Karabiner is your app. https://karabiner-elements.pqrs.org/
