How to repair a remote control 
Purchase the keypad repair kit, which is well worth the money, especially if the remote is a really expensive remote control, or no longer manufactured. 
The keypad repair kit usually costs in the $20 to $30 range. This kit comes with a solution in it that is needed to coat the keypad with.
Remove any batteries out of your remote control. Check over the remote control and remove any screws keeping the remote together.
