Hey guys I have a 2003 G35 Sedan. I changed out the burnt out light bulbs with LEDs behind the Infiniti clock on the center console. However, when I pulled the plastic trim piece out, I somehow accidentally snapped in half the circuit board that sits behind the red LED alarm light. Now my alarm system won't even trip or go off when I lock the car and open the door again from the inside like it usually does.

Does anyone know what the part is called?

Are all of the circuit boards compatible with each other in terms of G35s. (Thinking of doing a junk yard run)

How much does this part typically cost and should I take it to the dealer to have them fix it because I don't want someone to steal my ride because of a compromised alarm system.
