Update: used my hair dryer on it a bunch of times spread out over the last 5 hours so I don't heat it up too much. Was gonna wait till morning but I'm an impatient moron so I decided to test it rn without putting it together.
All the keys work perfectly except for the + key. That one takes a few tries or holding it down with more force to get it going. I'll try using the hairdryer over it and leaving it till morning, hopefully it gets fixed too. If it doesn't, any suggestions?
Edit: held the switch down with a pen and blowdried it for a minute and it works now. Thanks again dudes
