Wheel locks are very cheap. $20 will get you a nice set of 4. The trick is, when you install them, DON'T remove the original wheel locks. Most Honda wheels have 1 "locked" nut and 4 "unlocked" nuts (so 4 locked and 16 unlocked per car). If you replace the factory locked nut with a different locked nut, you've made things only a tiny bit harder for the thief -- they still need to remove 4 locked nuts and 16 unlocked nuts. If you replace one of the unlocked nuts with a different locked nut, now the thief needs to remove 8 locked nuts and 12 unlocked nuts. Now stealing your wheels will take twice as long -- so the thief moves on to an easier target.
