I have read my manual and done some searches looking for answers and cannot find anything conclusive so I will ask explicitly. I have read mixed results on Evo 8s having an alarm. I personally believe it does because when I hit unlock or get out of the car after driving, ~30secs later it will beep once. This does NOT lock the car, but opening the door without hitting unlock will cause the alarm to go off.

My question is: How do I stop this from happening? It's realllly annoying. If I get out and pump gas, it beeps once and I have to hit unlock to disable it. If my keys are in the car, well I'm gonna have an alarm-fest at the pump when I get in. What is going on here?!

 

did you buy it use or new

 

Used, but it's the stock Evo alarm(at least the remote operating it is)

 

Sounds like you have a passive alarm system that is arming itself. You need to turn that feature off.

 

There is no stock alarm. I would recommend getting someone who is familiar with the car to look under the hood and/or dash to see if anything is installed. Look for an auxilary power wire from the battery or fuse box. Just my 2 cents.

 

Whoops, yeah, missed that part. Yeah, there must have been something added to the car, and it is arming itself passively.

 

So the stock remote would be able to operate a 3rd party alarm system?

 

Yeah, passive remote systems can arm themselves automatically. Get it checked out, then I recommend getting an active system. Remember, a good alarm system should be the first mod you do to protect your investment. Let me know if you need any suggestions.

 

Thanks for the help guys. djscoto, I'll PM you on this since the mystery seems to be solved
