well there are a few options.. one is get the key off the keyboard and check the part underneath to make sure it is ok and another is since laptops have usb ports use a regular keyboard or even buy this roll up rubber keyboard i saw at frys
Get a wet towel and slide it between the keys.

The method of taking keys off a laptop keyboard is different depending on the model. Consult your owner's manual for details.
Well since you asked this question you must of used the keys on your laptop/computer! So you must of had the sense to count them...Total Keys = 84, but it depends on what computer you have....
A phone is usually much smaller than a laptop, so the keys have to be smaller and fewer :-) The keys also have to be harder, so they are not so easily pressed when you have the phone in the pocket.
