Trying to unlock google password and it want let me get out of it

Leave the phone on take the battery out this should reboot the phone

If rebooting the phone doesn't work, and it doesn't let you authenticate via the Google account (or you don't have one), you'll need to perform a hard reset, which would delete all of the data on the phone. To do this, turn the phone off, hold down the volume up button, turn the phone on, and keep the volume up button held down until you get a white screen with 3 skateboarding androids on it. go to clear data (navigate using volume keys, select using power button), then hit volume up for yes.
