Exactly how are you locked out? If you're stuck on the lock-out screen with a lockout pattern that you've forgotten? If that's the case, the G1 manual indicates the following:
"When you fail to draw the correct unlock pattern on the screen after five attempts, you will be prompted to wait for 30 seconds before you can try again. If you forgot your screen unlock pattern, touch Forgot pattern. You will be prompted to sign in using your Google Account name and password, and create a new screen unlock pattern before the Home screen displays."
