A friend's car key was not working properly, and he took it to an electronics repair shop. They quoted a very high price for the repair and my friend refused and got his key back.
Now he brought me the key and asked me to fix it, but before me the crafty person removed some of the components of the switch from the PCB.
This is the switch board. You can still see some components soldered there, but I have no clue.
If I search for the PCB number in Google, the same boards appear there. However, I don't have enough experience to determine what these components are and what their values are. Can you help me find these three components?
