Well, I just found this out a few months ago. The L and R buttons on my 3DS were worn out; luckily, I found out how to get them working again.
You need these materials:
- Your 3DS
- WD-40
- Cotton swab
- Paper towels ( or something else as long it can wipe away the WD-40 )
Let's begin with the steps. First, get your 3DS. You need to blow on the L and R buttons where there is just a little space between both of them. Second, get a few cotton swabs ( you probably should have one ) and apply a little Wd-40 on each end. Lift up the button just a little bit with your fingertips and apply the WD-40 to the button. Repeat the process for both buttons. Third, the WD-40 might/will drip down from the buttons so wipe it with a paper towel. Finally, blow once more into the buttons so that it dries into them.
Note: It will take some time for the WD-40 to clean the L and R buttons, so wait for a few minutes until they function properly. After some time, test it out to see if it worked.
The L and R buttons, also called the "shoulder buttons," are located on the back of the system on each corner; L on the left side, and R on the right. The location of these buttons are the same across all versions of the DS.

A and S
L and R are simply 2 buttons on the back of a Nintendo DS or a Game Boy Advance.
They do work, but you have to move your cursor over the box number. Then you can use the L and R buttons to your hearts content.
If you press on joystick you can change them.
Unlike the classic gamecube controller
The price can vary depending on where you take your Nintendo DS Lite to be repaired. However most people have reported that it can cost $100 to have the R and L buttons repaired.
