After months of having the random alarm issue on my ‘04 TSX, IT IS FINALLY FIXED. (posting this everywhere so those in similar situations can fix it the easiest way).
My factory alarm began going off for no reason and I tried the easy fixes first. It was not due to low batteries on my key fobs, or a depleted car battery, or any issue with the doors/trunk. It was narrowed down to the hood latch sensor. Acura dealership claimed there is no way to disconnect the sensor, but there absolutely is and it’s fairly straightforward. Before you take your car to a mechanic, attempt to clean the sensor, or even buy a new hood latch assembly, please TRY THIS:
1. Open the hood, and remove the black covering near the hood latch (the one with all the black clips).
2. Remove the grill held in by similar clips (2 on top, 4 on bottom) ((this step may not be necessary, but allows much easier access))
3. Remove the black casing around the latch assembly (3 bolts)
4. From here, you will see 2 grey wire connectors towards the bottom of the latch assembly. Disconnect by pinching down on the right connector and pulling apart. (I covered up these connectors with electrical tape just to be safe).
5. If the connectors aren’t visible from that point, you may have to remove the actual lock assembly. Just 3 more bolts, not difficult.
After reassembling the car, my random alarm issue ceases to exist. My alarm system still works with the 4 doors and my trunk, just not my hood. This was the easiest, cheapest, and best possible outcome I could have asked for.
