Silent Sales Force SSF is tricky machine because, over the years, they utilized 3 different types of locks and they are not interchangeable. This listing will get you a pair of the two most common types so you don't have to try to figure out which type you need for your machine.
Locks are no longer made for the 3rd type. If you get these and can't get either one to fit in your lid you can modify the larger one to fit. Use a file, dremel tool, or bench grinder and shave off just a little bit on the 4 points where it is rubbing and the locks will slide right in.
There are MANY different keys for gumball machines and it is highly unlikely that these keys will unlock the old locks in your machine. You will need to remove the old locks from the machine by drilling them out. We do not offer returns on this item so please do not buy them and then contact us to ask for a return because the keys didn't open your old locks. To find keys that will open your old locks you will need to recall the number that was stamped on your key.
