Samsung SCH-A310 Keypad Replacement

Remove the battery by pressing the button at the top of the case.

Unscrew the antenna by twisting it counter-clockwise until it is loose.

Slide the antenna out of the phone.

The black casing can be removed from the old antenna and used for the new antenna.

Using a #00 Phillips Screwdriver, remove the 4 (3mm) black screws from each corner of the back casing.

Use the wide plastic prying tool to open the back case.

To make this process easier, use the tool to push against this tab while gently pulling the back upward.

Repeat this process on the opposite side.

The volume button may fall out, but don't force it back in. Set it aside for reassembly.

When replacing the volume button, the rubber tab must be placed carefully into the space in the inner casing.

Pull the back plate up by gently twisting slightly towards the top left corner. When you feel the catch release, you can fold the plate back like a book cover.

If you accidentally pull the wires out, don't panic. The connector can be pushed back into place very easily.

Fold the circuit board back like a book cover just as you did with the back plate.

Be careful of this connector which goes to the front of the phone.

The silver contacts on the bottom of the motherboard are what recognize key presses; if the phone isn't responding to key presses, you will need to replace the motherboard here.

Simply pop the keypad out of the case by pressing the keys through the frame.

If keys were sticky, give them a thorough cleaning with soap and water; if they are damaged, replace the keypad.
