Sometimes the second button may need to be kept pressed for about 5 seconds to start the car if the remote car module is present.
Try to do that make sure your car is safely parked , and the emergency brakes applied and is engaged in park.Do this in an open area and not in an enclosed garage.
Some remotes require a double press on the butttons to activate this function.
You may try both functions on both buttons .
I hope this helps.
