This product, which is traded yes here under different names at different prices is only useful to deter casual thieves. This product was sold Millonenfach and the "key" is the same for all products. If you buy for 9.00 This quick release gets you supplied the correct key fits all other locks. Even if you have no key here, you get a simple pliers these "locks" on easily. Therefore, my advice is to prefer higher-end products not grab the same key have.
