You most likely have a bad hood latch switch you can unplug this switch until you get it repaired to stop the alarm from going off.

BEHIND THE DRIVERS KNEE PANEL IF IT IS FACTORY IT SHOULD BE JUST BEHIND THE DUCT WORK YOU CAN ALSO JUST UNPLUG THE PIGTAIL HARNESS IN BETWEEN THE IGN. SWITCH AND THE ALARM (PLEASE RATE THIS)

yes theres is, try locking and unlocking the pass/side door with the key. you can check for power at the starter at the small wire if theres power at that wire when the key is held in the crank position then you have a bad starter try taping on starter while key is held in start if its starts when tapping then starter is bad,heres a diagram to show you were to tap and where to check for power, hope this helps.

It is located on the bottom of the Driver's side dash, below and to the left of the steering wheel. The connector is recessed about an inch and has a black cover that has "OBDII" imprinted on it.

Have you checked any fuses? Does the climate control light up? If not then in the under hood fuse box (left of drivers side) check the ECU-B fuse should be 7.5 amp. Check the heater fuse in the fuse box inside the car it should be 15 amp. If the fuses are OK and only the clock is bad check out my site www.autoclockrepair.com I offer a repair service.
