Have the battery load tested.

I take help from online websites that have this service like helping in repair some like reliable-store have instant help.. others are a bit slow which I don't prefer... rest is up to u.. U get free manuals

SOMETHING IS AJAR OR THE CANCEL BUTTON IS BROKEN ON ONE OR MORE OF THE DOORS OR HATCH. SEE THAT EACH ONE IS IN PLACE AND CANCELS THE COURTESY LIGHTS

473P is the part number of the remote. 473P is the original remote for a Python1200XP alarm. I have the users guide.

The 'Keyless Entry & Burglar Alarm System" is activated. You must 'Disarm' the system using the Keyless Entry Remove (Key Fob) to "Reset" the system. The reason the engine won't start is due to the burglar alarm - it has a "Starter Kill" circuit which is activated when the alarm is activated. The alarm must be DEactivated to DEactivate the 'Starter Kill' circuit.
Another way to start the engine is to get in the car, put the key in the ignition and turn it to 'ON" and wait 3 to 5 minutes until the emergency flashers stop/turn off. Afterward, you should be able to start the engine. NOTE: This does NOT reset the burglar alarm. It will go off again when you enter the vehicle without using the remote/key fob.

put key in ignition switch leave in the off position, press the remote starter, if your car starts it is the transponder system it may need to be adjusted

Does your key have a chip on it? If it does its probably the problem
