Hello there.
I have problem with my 2004 USA rx8.
Recently alarm bacame supersensitive and wake me(and my neighbours) up late at night withough much reason. As quick fix, i removed horn and hazard lights fuse but cannot drive this way ;(.
I searched thruought the internet, and it seems like supersensitive shock sensor.
Removed some plasticks to decrease its sensitivity, and there: surprise!
There isnt any sensor.

(pic made with phone, sry).

i expected to see something like in this thread:

I searched everywhere close to its nominal place, but didnt find it.
it wasnt there: Screenshot by Lightshot either.

So my question is:
Is there any other reason for super-sensitive alarm despite shock-sensor?
Or maybe its placed in some different,odd place in US version?
Thanks for help.

Edit:

I have read "how to search" and found this thread:
https://www.rx8club.com/series-i-tro...ng-off-226318/

this may be an issue for myself aswell, gotta check it(didnt have ay accident though).

Edit2:

didnt help. alarm goes of whenever heavier car passes by.
Guess theres no choice ut visist Authorized MAzda dealer...

I had the same problem with my '04. The alarm would go off for no reason, especially in the middle of the night. One day I locked my keys in the trunk and I had a tow truck company break into the car for me. To my surprise when they opened the door the alarm didn't go off. I tested the alarm system later on in my driveway by locking the car with the key fob and leaving the window open so I can open the lock. Still the alarm didn't go off. This is a **** off since the alarm goes off for no reason but not when it's broken into. So looking at the owners manual it says that the alarm is only active when the trunk doors and hood are closed. So first I checked the doors just using the light on the dash, they were good. I checked the hood latch limit switch with a meter and I got no connection. When I bypassed it the alarm system worked. I assume this is the problem cause the switch is small and simple If the contact inside all of a sudden works when you lock the car, but then fails later on then the alarm goes off. I'm hoping for the best to see if this resolves the issue as I just did it today. The only other thing it could be is the control system for the alarm. The guy at the dealership calls it a "body control unit". So I'll keep this thread updated, but if anyone else has this problem check to make sure the door switches work.

Oh i forgotabout this thread.
Issue solved long time ago.
Reason for alarm going off was dead roof-light + its switch set to ON 24/7.
Apparently *s are very senstive to any dead lighting bulbs
