Locker Locks !

[Zebede4500]

I want to change the various external locker locks (Gas, Loo, Water etc) to a more secure barrel type key.
Found suppliers but they offer one lock, four keys.
I need four locks all on the same key. Anyone achieved this ?
Where from and were they easy to fit ?

Thanks
Zeb

Speak with a locksmith they can rejig the barrels of most locks to fit the same key, your local m/home dealer may have such a tool as they use it to do the locks on water caps etc when you lose one so all the locks are the same!
