Can a Mac boot when the right shift key is broken in the pressed position? [duplicate]

Here's the thing, the right shift key of my macbook is stuck, so it always boots in safe mode once I turn the machine on. Worse, I cannot log in since my password has lower case letters.

I tried resetting the NVRAM by holding Command - Option - P - R and also went into the disk utilities, however nothing I can do there helps.

I looking for a way to disable the right side shift key or alternatively enable the bluetooth via command line, since I have a wireless keyboard, but I cannot make either work.

UPDATE:

I woke up today and the key was working fine. However I do not trust on it. Probably when the MacBook gets warmer it will stuck again.

I downloaded a software called KeyRemap4MacBook, which can be downloaded from here. I followed this tutorial in order to deactive the key, this is a temporal fix while I make some saving to buy a new one.

Sadly, you might need to open the Mac and disconnect the keyboard.

Here is an image from iFixit.com's takeapart for the 15 inch model.

It is protected by a metal cage - but you won't need to do all the steps - just get the bottom off and disconnect the battery before working on the keyboard cable.

You will of course need a USB keyboard to work things temporarily and enable the bluetooth keyboard if you can't get there with a mouse or the trackpad only. Do read the cautions on the repair guide and be sure you are up to a delicate task. A proper Mac technician might charge $30 for this repair since it's quite easy for someone with all the tools and experience getting in to the Mac.
