Disassembling Nokia 6236i Keypad

Apply pressure to the battery casing (below the camera) with your thumb and pull towards the bottom of the phone.

Lift the battery case off of the phone.

Gently pull the battery out of the phone, using your thumb to apply pressure to the battery at the bottom of the phone.

The battery should lift out with minimal resistance.

Locate the notch on the bottom right corner of the phone.

Beginning at this point, slide the head of the screwdriver between the front casing and the rest of the phone.

Continue to slide the screwdriver towards the top edge of the phone.

The front casing should eventually pop off.

With the front casing removed, the keypad can easily be pulled off the back of the front casing.

In all probability, it will already have fallen out and no removal is required.
