If the open + locking the door in the house is carried out manually by means of the setting wheel is located at the radio drive and the electric drive is used only from the outside, is the battery life of the radio very long drive. I did have to change once. Again, a power connection is possible, but depending on the door and the necessary cabling due to the opening of the door ständigens and the associated strain on the cable is not unproblematic.
The wireless keyboard includes many settings. It can for example, different users and different access codes and different time frames are assigned. So the cleaning lady gets eg a code, which they can use only at certain times. The users are doing by typing their codes on the display with their behalf welcomed. There is also a party mode, in which the door can be opened without a code by pressing 1 button within a predeterminable time frame.
The included hand-held radio remote control is working properly, is not used by us but due to the existing wireless keyboard.
Overall, recommended for all who carry around any key with him or want to hand over to third parties. We decided to purchase and replacement after our daughter the front door key had been lost in the school and we had to change for security reasons a total of 4 simultaneous locking safety cylinder.
With regard to the cost it should be noted that there are cheap boxed sets and added cost of any necessary replacement of the lock cylinder.
Especially for further information. Also for installation is the HomeTec film recommended 2 on the side of Mr. plate (Abus.de).
