Macbook pro 2015, scissor switch key issue
Hello all, recently my e key has stopped working on my laptop.
I took the key off, cleaned it, and reattached with no issue, but it still didn't work so I figured it to be a problem with the silicon dome. I have a 2015 macbook pro, so back when they had scissor switch keyboards. I took it to the apple genius bar today and they were pretty unhelpful--the guy confirmed that the silicon part would need replacement, but said they don't carry them anymore.
I expected this, given that my laptop is so old, so I asked if they could harvest it from a key i don't really use that much. The guy declined, said he wasn't allowed to do that. Okay, that's fine. I asked if he could tell me how to do it, and he said "no no no, you need a special tool." I said "oh, what tool would I need to get?" and he kind of smirked and said "nothing you would have." (??)
I said "oh, what's it called?" and he didn't answer me, he just ignored the question and said that theres a place nearby that could do it and then gave me the name of the repair place. I went to the repair place and alas! the tool they used was a pair of tweezers.
Replacing the silicon cost about 30 bucks; they had extras and didn't have to harvest it from one of my keys. BUT after the service the guy charged me 60, saying that he gave me a new key and switch mechanism. To clarify, I did not want this nor did he ask, he just charged. I asked what was wrong with the old key and he just said it was "worn down." Bruh. All my keys are worn down, its an 10 year old laptop.
Anyway, I got home and have been doing my work and the key pops off and I haven't been able to click it back on. Also, the silicon dome is moving freely, so I put all the parts on my desk where I wouldn't lose them. Can I use glue to make the silicon not move when I try to reattach the key, or so I can use it without the key cap? If so, what kind of glue is safe? At this point, should I just get a bluetooth keyboard, or try to go back to the repair place with the receipt? The metal parts aren't damaged or bent, I'm just having a lot of trouble reattaching it for some reason. Any advice?
