Replacement Keys for Top Boxes etc

Hi
Inherited a big, locked, Carry All back box without a key, duh!!
I tried This website and entered the search term "Top box" lots of keys were found. I then tried the number stamped on the lock, in my case 010 and hit search.
There it was. I was a bit sceptical but thought what the heck it's cheaper than a new lock.
Paid £3.95 plus postage for it and two days later it arrived and guess what:-
I now have a massive lockable back box to fit loads of "stuff" in.

Good company, quick service and realistic prices.
Cheers
Adrian
