if you take off the keyCAP, you'll likely be sorry.

I expect that you don't have much machinery under there that could be affected by such a misguided attempt at heroic countermeasures. PROBABLY. you have a membrane keyboard under those plastic caps. A printed circuit board, covered with a dimpled silicone membrane. you can't get under just one "key". most likely, you've gotten a crumb or drip and some corrosion has happened between these contacts on the "7" key. and the circuit is closed making a 7 appear....

so sorry.

actually... fixing it.. very difficult 7/10. REPLACING it... very easy 2/10.

presuming of course, that you have a replacement keyboard. used? or new? ... depends on the popularity of the make/model. they are practically never interchangable.

HLJ's suggestion is as good as I can imagine if you intend to try to repair it. don't take the keycap off though, it will never go back on right. /voice of experience.

/aside
I once worked for a construction company and I often had to setup small networks in the jobshack at a jobsite. very very dirty environment by computer standards, but these guys were turning a hole in the ground into a building... so .. anyhow. once I revisited one of my installations and noticed the keyboard of the project manager's laptop was seriously dirty. filthy. so I unlimbered the local shop vac.. and promptly remove a whole stripe of keys.

FUCK

/end aside

you won't get that keycap back on, brother.

if you remove it, wash it, and let it dry very very very very days long thoroughly... you might make whatever was conductively icky in there dilute and wash away.

maybe.

or just price a new one. may be reasonable. If you go this route, you can definitely do the replacement. I've done scores, and you can do it.
