JDM '94 Impreza key replacement

[MSRTV]

I have a 94 Japanese import Impreza WRX GC8 and have been looking around at key replacements but dont know my key code and don't want a copy of my current ones as is quite worn down and one is slightly bent, obviously doesnt needed to be coded but not sure where I can find the key code or anywhere that would be able to find out the key code.


Anybody know a way to find your key code or a way someone could figure out what the key code is?

don't seem to see any other keys that look the same as mine either
