Well its really easy to code normal locks, hell I could do a standard lock with my eyes closed.
(another thing that could of been done is all the locks have a similar lock profile but vary enought to stop one secondary key being used on another lock, meaning the master Primary key will cover the whole 200 locks, I thinks thats right lol)
But the solex locks are another story all together.
Whats the key look like on the end????
