The Nemef Entr Keypad is an extension to your Nemef Entr door lock. Connect the keypad wirelessly to your door lock and you operate the lock with a unique code. The memory has a storage space for up to 20 different codes. So you give each user a separate code to manage the door. Making extra keys is therefore a thing of the past. In addition, thanks to the unique code per person, you know exactly who unlocked the lock.
