Windows 7 - key not working

it feels like something is stuck in r key , any help with cleaning?

From here, NO.

Take the key Off and have a Look, But good luck in getting it back on.

how to take it off? lol and get it back on too?

and sorry for not giving proper description, because the key isnt working im trying not to type much, as its only making the key harder.

Try blowing it with a straw or use a can of compressed air!!!!

oh thanks great idea! the straw one is easy, since i dont know where to find can of air, tho its fixed now , i just closed my laptop's lid, turn it upside down and patted the back of it, well all the keyboard dust came to screen and i only had to wipe it off but its fine as new now
