I have heard that folks who own this phone in the UK can simply take it to an authorized Nokia repair center and and have the keypad replaced free. Since I am in the US this was not an option.
I found a replacement keypad online for $5 + S & H so I bought it. I worked at a mobile phone accessories shop for about a year so I felt like this was something I could do myself. Hopefully this guide will help another poor American out.
Step 1: The Right Tool for the Job
Optional: hair dryer, microfiber cloth
Step 2: Remove the Battery Cover
Remove the battery.
Step 3: Remove the 2 Lower T6 Screws
Step 4: Seperate the Backplate
If you do not have this tool, or one like it do not attempt this. If you're like me you will likely be too anxious and arrogant to ignore this warning. So at least don't use anything metal as it might scratch or bend your fragile phone parts. Perhaps something like a guitar pick might do the trick.
Hint: The latches seem to be at the "hips" of this phone's sexy hourglass figure. Don't expect to be able to separate the phone unless you pop these free.
Step 5: Seperate the Front Plate
Step 6: Replace the Keypad
You may want to take this time to clean off the screen using a microfiber cloth or your shirt
Step 7: Reassemble
Now your phone is like new!
And please: Don't be one of those dweebs that leaves the plastic protector on his screen for a month.
Be sure to favorite this so you can come back in 6 months when you keypad inevitably fails again as a result of poor design. It's really a shame because this really is a great phone considering.
