A two-part keyboard separately connects to an electronic device to input data to the electronic device. The two-part keyboard includes first and second housings that respectively have a keyboard portion. The two-part keyboard also includes a base, a connector, and a controller for receiving and processing a signal. Two ends of the base respectively and movably connect to the first and second housings. Due to the connection between the base and the first and the second housings, the first and the second housings may move toward or backward. The controller electrically connects to the connector and the keyboard portions on the first and the second housings. The base is contained within the first and the second housings when the first and the second housings move toward to contact. The base is exposed between the first and the second housings to electrically connect to the electronic device.
