Motorola T720c Keypad replacement or cleaning

At the base of the antenna, use your fingers to unscrew the stem counterclockwise.

The antenna will pull out with little effort.

On the back of the phone, locate the tab with the down arrow.

Using your finger, press the tab and slide the back cover down to release it from the phone.

Inserting your finger in the recess at the top edge of the battery, pull the battery away from the housing to remove it.

Locate the three screws that secure the back battery housing to the phone.

Use a Torx T6 screwdriver to unscrew the screws and then remove them with your fingers.

Using a spudger (not shown), separate by gently prying the front from the back of the phone housing.

Remove the back.

In the same direction you would flip open the phone, use your finger to gently lift the circuit board from the plastic keypad.

While avoiding contact with the inner electronics, use the spudger to lift the plastic keypad from the phone.

Using a lens cloth, wipe away any build-up on or between the keys.

Wait for the keypad to dry before reassembling.
