They are more secure than not having them. As with all wheel locks (OEM, and aftermarket) there are a limited number of key combinations available. I worked for an auto recycler summers while in college and we had a tool box full of "keys" for almost all locks. In 2 years I had 1 set of locks that I did not have a key to.
