Why Left or Right?


Basically i wanted to make it easier for you to understand which key you are buying, especially when looking into a keyway.


for example the standard Yale rim cylinder accepts a 1A key


As you can now see the lowest ward

(the part of the lock that sticks out)

is on the right hand side


This is a standard profile for most common locks and is known here as a "Right" key


The other main profile but not as common is the "Left" key, as before but this time the profile is "reversed"


for example our U-5I key

As you can see the lowest ward would insert into the bottom Left of the key, hence a "Left" key,

aka a "reversed" key or profile


another good example would be the universal padlock set

Side by side you can see the different profiles
