An unlocking method and a mobile terminal are provided. The unlocking method includes: in the case that a mobile terminal is locked, a touch chip determines whether a fingerprint verification operation is detected; in the case that the fingerprint verification operation is detected, the touch chip sends control signals to a central processor and a fingerprint driving chip; the fingerprint driving chip drives, in response to the control signal, a fingerprint sensor to collect fingerprint information, and determines whether the collected fingerprint information matches preset fingerprint information; and if so, the central processor unlocks the mobile terminal in response to a second control signal and a determination result from the fingerprint driving chip.
