How do you change a drill bit in a drill?

Answer:
Depends on the chuck. Adjustable chucks can be loosened by hand, simply twist the end of the drill. Older (or heavy duty drills) need a key to open the drill chuck.

I have a McKeller cordless 18V electric drill with no hand adjustable or key adjustment visable???? I'm confused
