BTW, can I recommend making use of the subject line?
A lot of people (myself included) are irritated by mystery subject lines like that. Many people don't know the first thing about locks, so reading this thread is a waste of time, but they have no idea what the thread is about unless they click on the link and read the first post. On the other hand, people who know things about locks might pass this thread over without ever looking inside because they had no idea that the contents of the thread concerned them. Using the subject line is better for others and for you.
A topic like this should have a subject line like, "Cabs with locks but no keys . . . can anyone help?" or, "Is there a way to open a locked cab without a key?"
