Fixed stuck key
FYI...looked up threads concerning stuck keys and found this one. Had a stuck key issue that I was able to fix myself on my Mac Book Pro (pre-unibody 2008). Not sure HOW it occured but the "K" key looked like it had been smashed in on the bottom. Key still functioned but not well.
1. Pulled out "K" key from the top--just snaps off. Looked fine.
2. Pulled out "L" key (which was working normal) to see what a normal key should look like underneath the hood.
3. If you do this you will notice that the plastic pieces underneath should lay flat, however you can lift one side up and it forms a criss-cross that lifts the other side up simultaneously. My "K" key had plastic pieces raised up and I saw this was caused by one of the notches that is in the middle of the criss-cross laying above rather than below the criss-cross area.
4. So if this is your problem just adjust the notch on the bad key back under so that when the plastic pieces are at rest they lay flat.
5. Next line up the lid notches with the top grooves of the plastic laying flat and push down with some force until you hear a snap and they snap into place.
6. Works good as new.
