Disconnected the horn (probably could have removed the fuse, but I was down there anyway).
The alarm was now going crazy, but no horn (only lights).
Removed the latch, cleaned it up. Cleaned up the alarm sensor. Put everything back.
Alarm is still going crazy. I disconnected the battery in between tests to save battery life.
Disarm the Security System:
Disconnect the battery, Make sure all doors are shut. You can have the hood up (I did). Reconnect the battery. (I still have my hood up) Walk over to the passenger door. Use your key to lock the car, then unlock the car. Alarm turns off.
Everything is fixed. My hood also shuts like it should (before the cleanup it was the biggest pain), no issues there.
Hope someone else that has this problem finds this helpful.
A) Have the alarm system disconnected/removed.
B) Get either your dealer or an independent audio/security system shop to get you a remote. If you know what RPN and FCC code you need, many remotes are available on Ebay for a modest cost.
Do you know where I can find my RPN and FCC code? I would like to order some used remotes on ebay.
