description A keyboard apparatus and a detection method for status of keys thereof are provided. The detection method includes the following steps. First lines of a key module in the keyboard apparatus are driven to a first potential. Whether any key on each of second lines in the key module is pressed is detected as a first detection result. The second lines are driven to the first potential. Whether any key on each of the first lines is pressed is detected as a second detection result. One of the first lines is sequentially selected, and a press status of each key on the selected first line is scanned through the second lines so as to generate a coarse scan result. The press status of each key is obtained and whether the press status is misjudged is determined according to the first and the second detection results and the coarse scan result. 本发明提供种键盘装置及其按键状态的检测方法。此检测方法包括以下步骤：将键盘装置的按键模块的第线驱动至第电位，且检测对应于按键模块的每条第二线的任按键是否有被按压以作为第检测结果。将第二线驱动至第电位，且检测对应于每条第线的按键是否有被按压以作为第二检测结果。依序地选取其中条第线，并通过第二线来对所选取的第线的每按键的被按压状态进行扫描，从而产生粗略扫描结果
