Shift key always depressed after liquid - how to avoid Safe Boot?

[Jugney]

I work at a local mac shop, and a customer has a 13" Macbook Pro (Late 2011) with a bit of water damage, the result of which is that the left shift key is always registered by the system.

I installed Karabiner to see if I could disable that key, and it works when the OS is up. The problem is, during boot the system registers the SHIFT key and goes into safe boot - which disables Karabiner since it's a third-party login item...

Is there any way to force normal boot on startup through some fancy commands?

Replace keyboard. Quit messing around.

Maybe put in an external keyboard?

Or you might even have to external everything, keyboard, mouse, display. Close the clamshell, and let it boot. Might just default away from the internal keyboard.

Have you tried popping off the shift key and giving is a bit of a prod?

In case two recommendations wasn't enough, I'll throw another in.

Replace the keyboard. I'd also make sure no other components have any liquid damage while you're testing it apart.

Personally, I don't trust any components with liquid damage.
