I just bought a 97 Corolla CE with alarm system. I believe it is a factory installed system, with a little red light mounted in a small removable dash panel, to the left of the steering wheel. I was given one key with the car, which unlocked the doors and started the car. It is a simple metal key, no remote built in. When I test drove the car, I did not realize it had an alarm system. I locked the car last night while at the store, and used the key to unlock it, all without problem. But I had locked the doors by pushing down the individual buttons on each door. Last night I used the power door lock switch on the driver's door to lock everything. This afternoon, I unlocked the driver's door and the alarm went off & I immediately slammed the door. Alarm continued for about 20 seconds. I tried the passenger door with the same result. How do I get into my car without setting off the alarm? I tried getting in & putting the key in the ignition. I cannot start the car! How do I disable this alarm and still be able to start the car? I don't have funds for a tow or a mechanic.
