Your car was not ever actually equipped with a remote start. This means that someone has added onto the factory system and added a remote start. This feature normally is simply an add on to the keyless entry already equipped. Depending on the actual manufacturer they work different. You may want to try to hit the door lock button once to lock the doors and then press and hold the lock button once again. This should cause the vehicle to start. Feel free to contact me with any questions or problems! Good luck!
