I locked the car with the button. Then, I unlocked the car with the key. The alarm began sounding and would not quit. After about 5 minutes, the alarm stopped. Now, my car won't start.
Thats because it in security mode... its not going too
reset the alarm and then unlock the door with the key fob.
if this doesn't work get a good mechanic
Try locking and unlocking with the button and see if that works- this should reset the security system-Denny

YOU need to locate the RESET alarm button. They are in different places but the most common are UNDER the steering wheel column, glove box, drver side kick panels or in the middle console someitme hiddedn. The button is small and not sure if your alarm is factory or after market.

SOURCE: First: alarm went off on its own.(mazda 6 2003).
there is often a small back up battery in the immobiliser unit itself, if you can locate this unit and replace the battery with the ignition on / engine running, then it should not need recoding and work fine after that. The other thing that could be wrong is the key battery (if the fob has one) or the transponder chip in the key head. If the key signal is low the immobiliser lamp will light during driving, but this does not explain the alarm going off. That is more likely either a poor vehicle battery, alarm / immobiliser back up battery, or another electrical fault such as water leakage into a tail-light or even the alarm unit itself when it rains. A lot of alarms are voltage sensing and when the vehicle is parked they will alarm if the battery voltage changes for any reason, though not during driving so the battery in the immob is my first choice to look at.

I do not have a key fob.
then try this... turn the key to the lock position and hold it for about 5 seconds... then let sit for a minute and then try to unlock the door... do this on the drivers side only. If this doesn't help you need to seek help because we don't know if it's an factory set up or a dealer installed item or someone installed it in their driveway
