I own a 2003 mazdaspeed protege, Yetserday I had installed a new deck for the car after I finished hooked up the negative back to the battery and after about 15-20 seconds the alarm started going off and my car no longer starts. I have no clue what this could be, either than a security feature. I re checked all my wiring and it was done correctly. My Key fob no longer works either, I called someone and they said all I need to do is re program the key fob to disarm the alarm which I have no clue on how to do. On my key fob it says Naldec Corporation and I tried searching up a user manual and I could not find anything. Does anyone know the solution to this? or any information that would help? Everything is appreciated thanks!

 

I don't have a clue man. There is something wrong with the alarm systems on at least 2002 model Mazda's and up. I have a 2002 protégé, and the alarm starts blinking about 2 minutes after I get out. Then...... I have to hold the alarm bypass button and turn the key to accessory within 45 seconds or the alarm starts going off in random tones><<?? Crazy... I have been dealing with this problem for awhile now, and its getting old. In the past two weeks I was just driving along (AFTER HAVING TO DEAL WITH THE REGULAR HASSEL OF HOLDING THE DANG OVERIDE BUTTON TO START THE CAR) and the damn alarm starts going off while I am driving down the road. When this happens the alarm override button won't even work. You just have to wait it out.. I am at whits end with this S@t. I even moved the override button. I mounted it in the little plastic panel beneath the steering wheel for easy access. SOOOO FRUSTRATED!!
