5 stars for 5 key

Had me these cylinders ordered because the old apparently hakelte when closing. As it turned out later, however, this was not the old cylinders, but the old lock case in the door. With a little oil into the lock case the Hakeln was gone also. Suuper I find the 5 key. The can, no matter how around, stuck in the cylinder. So there's no up or down (smooth or serrated side) and not "tip". Since there was only one key from my old cylinder, the purchase was correct despite erledigtem Hakeln using oil and I am happy. In addition the new cylinder has a hazard function, ie, you can shut on or, although a key is inserted in it. This, of course for the key owner also requires trust.
A no-name cylinders can be expensive if you have to leave open the door from the emergency service. So better -Markenware !!
