With the Yale ENTR Code Panel you can easily open your smart door lock with a self-set code. This way you open your smart door lock with a code and you don't have to search for your keys or your smartphone. The combination lock has a memory for a maximum of 20 codes, the first of which is stored as a management code. This allows you to add new codes. For example, you give easy access to the babysitter or cleaner and you withdraw the access for that person if that is no longer necessary. You connect the code panel wirelessly to your existing Yale ENTR Kit.
