My remote wouldn't respond to some button presses anymore. The contacts became dirty after long use. So I opened it and cleaned the contacts. (I used pure alcohol - please take care not to brush off the carbon layer of the buttons.)

The remote has a bottom and top part. They are held together with plastic clips.
Don't forget to remove the battery, just for good measure.

Use a spudger, prying tool or a flatbed screwdriver to pry open the two halves. Start at the center.
The two halves are clamped together firmly.
Work your way to the front, and then back again on the other side.
See the next step for the location of the clips.

The clips are located 3 centimeters apart. The first clip is 1 centimeter from the front of the remote.
The hooks of the clips are on the bottom halve of the remote and face inward.
The top halve of the remote has indents where the clips grab into.

4 단계 All parts of the remote

These are all the parts.
I cleaned all parts with a toothbrush first.
Then I cleaned the PCB and the back of the silicone buttons with pure alcohol.
Make sure not to brush too hard! You might remove the carbon layer that is applied. (It's the carbon layer that makes the electrical connection, so it's essential).
