What method(s) do you use for cable locking laptops/computers? Key, combination or both? We are looking for a solution that uses a key, but need 50 cables with the same key to avoid a rather large key-ring. Are cable locks made in quantities of 50+ with the same key and where do we purchase from? Stores has a couple different locks, but do they all use the same key?
