Flip the keyboard over so that you are looking at the keys.

To locate the solder joint on the board, count the number of rows down and keys from the right or left side to the broken key/switch.

Flip the keyboard over so you can see the solder joints again.

Using the number of rows and keys from the left and right, count the solder joints which will find the solder joint you need to remove.

It is helpful to count from the side that has fewer keys until the broken switch—in this case from right to left (the second row and five keys to the left).
