I got tuned 2 days ago.
But the problems started today.

im outside of the car, i unlock the car, open the door and the immobilizer turns on and the cars alarm goes off (not the panic alarm) this is a completely oem alarm and iv had the car for 5 years now

its a 04 ap2. im clueless it wont let me start the car

no matter what i do the alarm keeps going off whether i lock or unlock the car inside or out once i get it the alarm turns on and wont let me start the car.

 

what kind of engine management? piggy back im guessing since your immobilizer still works (no pun intended)

 

are you unlocking the car with the key or the keyless keyfob?

If your OEM is armed it will cause this exact issue. You'll need to hit unlock on your remote twice to disarm the system.

 

Im running ems version 1
that what I dont get ems doesnt control it anymore.
when i unlock the car outside even if I hit the unlock button 4 times the red light is still flashing inside the car and when I open the door alarm turns on.
it's the oem alarm im stumped on this I pulled out a blue fuse and problem is solved but still doing get why its doing that?

 

is the oem alarm tied to the immobilizer? if so, since you don't have the immobilizer anymore, that could be messing with the alarm

 

The alarm should be completely separate form the immbolizer.
Try this: Use your key and unlock your driver's door with it. Does the light turn off?

 

i tried that yeserday i locked the car outside(red light flashing). then used the key to unlock the car and the red light still flashed. when i opened the door same thing car alarm .

theres the ticker underneath the stearing column that is a black box there was a big red fuse next to it and a big blue fuse both were taped together i pulled out the blue fuse and it turned off the red light.

I'm still irritated I wanna know why this is happening

 

If you have the factory add alarm alarm you can easily just remove it:
