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

Universal padlock keys

 

Side by side you can see the different profiles
