According to the packaging, the smart card hotel door lock comprises two parts: the lock mortise and the lock panel.

Hotel Door Lock Panel

The hotel door lock panel is divided into front and back panels. The front panel comprises a hotel lock mainboard, an exterior door handle, and a mechanical lock cylinder.

The back panel comprises an interior door handle, hotel door lock battery packs box and a thumb knob. The front and back panels are connected by two handle spindles inserted in the lock mortise and then joined by fixing screws at four corners. The exterior handle can be used and opened after reading the card, and the interior door handle can be used to open the door at any time from inside.

The lock mortise is the core component of the hotel door lock, responsible for the hotel lock’s main locking work. The deadbolt is controlled by the thumb knob of the interior handle, and the lock latch bolt is governed by the handle on the front and back panels.

The mainboard is connected to the lock mortise, and the lock mortise is connected to the battery for the power supply.

The above is a simple description of the hotel lock structure.
