In keystroke recognition technologies, a method and a module for updating a keystroke reference, and a terminal device are provided. The method for updating a keystroke reference includes: receiving a pressing interrupt sent by a keystroke chip; obtaining a plurality of pressing capacitance values from the keystroke chip, where the plurality of pressing capacitance values include a capacitance value of the keystroke chip at a generation moment of the pressing interrupt and a capacitance value of the keystroke chip at a scanning moment next to the generation moment of the pressing interrupt; and setting a release reference of the keystroke chip according to the plurality of pressing capacitance values, to improve interchangeability and anti-interference of the keystroke chip with no extra burden on a main control chip.
