Step 1: Open Up the Remote
Following the procedure for your remote's make and model, open up the remote to expose the keypad's black contact points that touch the circuit board when depressed.
Step 2: Stick Aluminum Foil Dots to Contact Points
If you are using the repair kit, simply peel off one of the included adhesive aluminum foil dots and stick it on the malfunctioning button's black contact point. Press it tightly against the contact point for 10-15 seconds to help adhesion.
If you are using your own aluminum foil and double sided tape, then first place a strip of double sided tape on the some aluminum foil. Using scissors, carefully cut out a piece of aluminum foil with double sided tape attached that roughly matches the size and shape of the contact point. Stick this cut out piece to the button's contact point.
Step 3: Reassemble
Put the remote back together and enjoy!
