aluminium top box lock help

[oly]

i think this may be covered here so looking for a link but
i have a new aluminium top box and a set of locks.
i want to key the locks to the ignition key.
i have two barrells and a load of different shape pins.
is there as step by step guide to do this with pics on here?
i can only find the guide for vario panniers
thanks

The actual keying is the same as the vario panniers....

The difference is how you remove the lock barrels.....Take the panniers off the bike, into the kitchen is best...

Put the key into the lock and look at the back of the lock. There is a spring loaded pin you need to keep in place as you turn the key. I use a thin sharp knife. As you turn the key the pin touches the edge of the knife, and contracts level with the barrel tube, you then pull out the lock with the key

Sounds more confusing than it actually is.... then follow the actual leaf replacement thread you have already found
