If anything it might even be cheaper to buy a cell phone at any local Pawn shop. This will be a really hard and precise task so if you don't want to put in that much time and effort I suggest you either get a new membrane or send it back to the company. In order to reshape it use a small metal screwdriver or something hard and just go around and flatten the middle but raise the sides of the individual Pog.Ģ- If the membrane is beyond repairing you will need to either buy one or makeshift one. Put it back on the hard surface face down and press the corresponding Pog. To test this once you're done reshaping it. When these little Pogs are dented as you can see here, you can press all you want but it won't make a proper connection an thus you won't be able to register a touch for that particular key.ġ-Reshape the pog so that springs back whenever you press one it. This creates a connection between the metal in the circuit board and the Pog that registers as a touch. When you press a key, what happens is that the little bump in the actual keypad push the Pogs on the mebrane down. They are slightly larger so they don't make a connection. The way the little metal Pogs work is that they sit on top of the little golden circles corresponding to each key. This is the reason your keys weren't working. Now on to the first step!Īfter you have put all those components aside take that keypad membrane and set it down with the metal Pogs facing you.

We will see what these look like and how it works later in the Instructable. While the actual keypad is comprised of the buttons you press, the keypad membrane is what allows the keypad to register a touch to the circuit board (it is basically a thin, white, plasticated film with small metal sections of a hemisphere that act like mini Pogs). Now keep in mind, the keypad membrane and the keypad itself are two different components this is true for most models of cell phones, though there are exceptions.

This is where we come in and fix the problem. Thank you keegsta123ģ- The phone's keypad membrane is broken or dented. Click here to see a great Instructable that demonstrates this principle. The rice will draw out the moisture and if there was not too much damage the phone should work fine.

The only thing to try best for a phone that's been subjected to moisture is to place it in a sealed container with rice. This issue is one that a certified technician would have to take care of and is nothing that we can fix here as it would be time consuming and expensive.Ģ- Because of moisture or heat, again, the circuitry could be damaged. Generally, when a cell phone's keypad is not working properly it could be one of three different reasons:ġ- Due to shock from a drop, circuitry is damaged thus no matter how hard you press you will never get the phone to register it. It has to do with malfunctioning keypads. Today's fix is real easy and depending on what tools you got, will probably take you between 10 to 15 minutes. In turn the cell phone will rebel and stop functioning. Most of us have cell phones and from time to time we tend to drop or maybe treat them with a less-than-delicate manner.
