The pin tumbler mechanism originated first with a primitive lock designed by the Egyptians about the time of the pharaohsIt wasn’t developed again until Linus Yale invented his pin tumbler lock which were originally supplied for bank and safe locks. 

Current cylinder locks come in all shaped and sizes from a standard yale type rim cylinder on your wooden front door, cam locks, padlocks, screw in cylinders and the most popular by far is the euro profile cylinder which is found in almost every UPVC and aluminium door ( old aluminium doors not using a multipoint mechanism have an oval cylinder. ) 

Most cylinders are available in various finishes:

 N or NM = Nickel / Nickel Matt 

PB or B = Brass or Polished Brass 

CH = Chrome 

There is a large amount of different manufacturers almost all of them making a full range of every type of cylinder and as with most things there are good quality products and poor.
