lockscreen pincode not working? urgent please help topic

hi i am rooted and have a clockwork mod recovery. i set a lockscreen pincode but for some reason it is not accepting the pin which am 100% the correct pin. just keeps saying incorrect. it does not give me any forgot pincode option or sign in with google account. i really dont want to do a factory reset. can anyone tell me if there is a apk i can flash which resets the lockscreen pincode to none? thanks
