So I have a realy dumb sister who thought itd be a good model to put 3-in-one oil in the keyholed grounds her key wasnt working. Any normal individual wouldve known the hole is fine and the key is the problem... not her. Anyway, immediately everyones keys dont work, and someone must always be home to open out the door. This is very incovinient, and my hands are greasy and stained. It's be 2 days now, but I cant take it. I hold no idea how to clean the keyhole, and I dont want to do anything that might mess it up even more.
Someone please assistance me.
I would flush the key hole out near vinegar, or some paint thinner to remove the oils. That should take thought of it. Best of luck on your project! WD40 ,then clean that out near lighter fluid. You can buy lock lubricant at the hardware store to put in after the lighter fluid evaporates..
First try twirling a wood tooth pick in the hole.Then dip the pick in a lighter fluid such as Zippo (Ronsonal) fluid. And if that doesn't work, try putting the lighter fluid on the push button and insert it. If that doesn't work, change the lock or call a locksmith. WD-40 is not unpromising. Alcohol is a good solvent.

But just wadding it with oil won't produce the other keys to not work. It won't clog it up. It would take months save a year or two for the oil to get old-fashioned and gummy, collect dirt, and cause a problem.

I think you enjoy a bad lock cylinder.
Answers:    Flush it out with a large amount of WD-40. The solvents surrounded by the WD-40 will thin the oil and rinse out it out of there. Don't be shy- use lots of it. You are going to have a mess, so try to lock in as much of the gunk as you can with paper towels up to that time it runs down the door.
I used WD-40 once to remove some sticky oil/tar gunk. It worked pretty well as a solvent (and street lamp lubricant).
