Introduction
If your LG Chocolate 3 keyboard is broken or malfunctioning, this guide will assist you in replacing the keypad. A keypad can be damaged from frequent use and become unresponsive. To access the keyboard, you will remove the battery, the rear case, the side buttons, and the motherboard. This is a complex repair with many small parts, and the process will take about an hour to complete. If you wish to reassemble the phone after the keypad replacement, follow the steps in reverse order.
