How Do You Remove the PCB 3 Button on an Audi Key FOB?


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.
