Button won't depress properly constantly triggering

So the 1 button has been causing me some problems, sometimes when try to use it it randomly is really hard to use compared to the other keys. It then triggers itself every time I press a different key and sometimes if I don't even touch the calculator. It makes it hard to turn off cause the 2nd button gets use by the one key. I sometimes have long clearing battles where every time I clear a new one spawns before propagating. Note sometimes it works perfecylmfin other times not so much

Asking for help repairing it beceuse I don't even know how to remove the front case.

Answer this question I have this problem too

Is this a good question?

Hey It sounds like you have something stuck under the 1 key. Unfortunately, as far as I know, there's no easy way to access the buttons on this calculator. You'd have to go through the back cover which requires you to

  1. Remove the battery
  2. use a small hexagonal screwdriver to remove the back
  3. remove the LCD (I'm not completely sure if this is necessary)
  4. Find a way to remove the motherboard (it's a pain and I've never been able to do it before.)

After that, you're on your own, since I've never been able to take off the motherboard, I don't know what's on the other side. Hopefully you can enlighten me if you decide to try it!
