IMPORTANT: A specific laptop model may use several different key types, some Dells can have 8 or more types of keyboards.  You must check the hinge mechanism of one of your main letter keys matches that in the picture to ensure it is the right one for your keyboard.  It is your responsibility to check compatibility, refunds will not be given for incorrect purchases.  While supplied with the hinge attached it is sometimes easier to separate the key from the hinge and fix the hinge to the keyboard and then affix the key. All keys available This listing is for one key only.  Supplied with hinge mechanism as well (please be careful fitting) but not the rubber central nipple unless requested as this is normally part of the underlying keyboard membrane sheet, no problem if you do want one - I will just cut it out. Please indicate which key(s) you would like. Feedback always left once I know you are happy. ref 194
