there was also 2 tools for the TOY43R lock in usa , the 1st release that worked well , then it was found that the tool didnt work in a later generation of the lock , the tool was then redeveloped and rereleased to take this lock in as well , sadly both versions i believe are still sold due to distributors having stock of each .
