Del key on my keyboard not working.

I have a 5 year old mechanical keyboard and recently I was using the ctrl alt del command alot when suddenly the del key stopped working.At first it would work occasionally but then it stopped working altogether(all in a matter of 20 mins).The keys around it work and the del key in the numpad works too which is great.To make sure nothing is registering when pressing the del key I went to my Discord settings and tried to use the key as my push to talk key but was not registering no matter how hard/light I pressed it.Other keys around it and the other del key in the numpad registered.

​

I could probably start using the other del key but I was wondering if anyone had somewhat of a similar problem.

Might be time for another keyboard :/

​

Also I removed the key cover to see if anything was bad but nothing seemed out of place.The key isn't stuck or slow either.It even does the usual mechanical keyboard click.Did the circuitry behind simply die?
