Completely disable a specifict key {solved...kinda}

Question

{Solved} ---> since i couldn't find a way to solve my problem i decided to remove the keyboard and manually cut off the connection of the key, i am glad to say it actually worked and that it seems the rest of my keyboard isn't going haywire i am a bit....dissapointed that i wasn't able to find a more....elegant way to do so (not cutting the key off, for example) but, it works.
thanks to all of you who read my post}
My keyboard's(laptop) "Left" key is broken (due to a water related incident) so i am trying to find a way to completely disable it. I kinda found one using "xmodmap -e 'keycode #=NoSignal' and that solves most of my problem, normally there are no problems and i would be able to type whatever i desire without issues. The problem arises when i have to modify some file for one reason or another from the terminal and i have to go into SU mode, it ask for a password but for some reason my left key "reactivates"  it isn't actually moving my cursor but inserting some other text. It also bothers me when im trying to select something in a right click menu(or any sort of menu that allows for keyboard based selection) that has sub menus in it. I verify xev and indeed even if its not actually doing what it should (for example moving my cursor as a type) it is still stuck (aka spam as if i was holding it).
So i wonder if there is a method to completely disable my left key?
apologies for the bad grammar.

First, think really hard about why you want to disable the PK. If it turns out that you really must change the PK, then do this:
1. drop the primary key.
2. recreate the PK with the DEFERRABLE INITIALLY DEFERRED clause.
This will cause the PK to be created with a non-unique index so that if you disable the PK, you will not get an ORA-1 exception. It will also defer checking and enforcing the PK until you commit. This could eliminate the need to disable/enable the PK.
