You can have an immediate lock change or cylinder exchange done at Zedan and Handke in no time at all in Nuremberg, Fürth and the surrounding area at the time you want. The classic cylinder lock, which is often also referred to as a profile cylinder, offers a rather low level of protection against intruders. With special locks you can achieve a much better protection. As a result, your door can no longer be opened within a few seconds with the right technology, but becomes a real challenge for the burglar.
