Do an actual full source check as directed by Google .
Starting with Android 4.2, the key lock source is in frameworks/base/policy/src/com/android/internal/policy/impl/keyguard . There you can see the mirror on GitHub on the Internet (I linked this link to the release of JB MR 1.1 in case of a change of location in a future release).
When this question was answered, Android 2.3 and below had a screen lock source frameworks/policies/base/phone/com/android/internal/policy/impl . You can also browse these sources online in your GitHub mirror ; this source is still kicking in the current repo, but has not been updated in a few years.
