The PCB board inside your Audio key FOB remote is the main circuit board that the buttons on the outside of the FOB connect to. To remove this PCB board you will need to open up the FOB itself. The job should only take you a few minutes. Instructions 1 Insert a small flat-head screwdriver in the seam where the top half of the key FOB meets the bottom half. 2 Work your way around the sides until the two halves separate. The PCB board will be revealed in the bottom half of the key FOB. 3 Remove the PCB board and set it aside. To replace the board simply fit it in the bottom housing and fit the two halves of the housing together. You can apply some hobby glue to the edges of the two halves of the FOB to secure the two halves together.
