HOW TO KEYLOCK THE LG500G FOR THE DUMMY (me.)
Exit all menus back to the main screensaver. Locate the lower left key with the padlock on it. PRESS and HOLD. The screen will display the message that the keys are locked.
TO UNLOCK: press any key to activate the screen. Press the upper left button with UNLOCK over it - a screen pops up telling you to press the upper right button with YES over it. Press , ONCE , because it becomes the dreaded BROWSE button on unlock.
This and much more in the yellow paged section, "Using your Tracphone," in the Services Guide packed in the clamshell, section 3.13.
IIRC my old TF Nokia bar phone was the same - and the Browser key on it easy to hit, too.
