After smoothing out the left over latches you are ready to drill. Drill three holes at the corners of where the old latches used to be. The picture shows the rough spot where you'll want to drill

Please double check and adjust your drill hole placement if you think it's needed. This is what I did, and it worked.

Remember to use a very small drill bit. The plastic walls are thin, and the screws we should be using are very small.

Be careful not to drill something you shouldn't and do not drill at an angle or drill through the wall of the battery compartment. This is the only real hard part of this repair, take your time and think about what you are doing.
