Thank you for using just answer.
How many keys do you have?
Ok when the key is turned on it only flashes 1 time every 2 to 3 seconds?

I need you to hook up your battery the way its supposed to be with no jumper cables or charger connected, does the vehicle have any electrical power?
Whats the battery voltage?
