Got some bad news...replaced the switch but it didn't resolve anything. I don't know whats wrong. Can it be an electrical problem?

I have talked to my personal friend who used to work for acura and he told me he replaced hundreds of switches and it always fixed the problem.

My alarm kept going off even after I inserted my key into the ignition before I found out that I couldn't shift out of park....perhaps the alarm caused some wires in the electrical line to go bad?

I know my brake light bulbs are fine since the tail-light function is on when my headlights are on. (they stay solid though, even when pressing on the brake)
