Key remote functions not working

[JamesDean]

Shipped the car, all was OK loading and on receiving end 2,000 miles away.

Friend let his buddy drive it once, and no one can say what happened.

I got to car four weeks later, totally dead battery. I foolishly paid AAA for a new one after the guy jumped the existing and started car.

Alarm gong rings when driver door is opened, and key not yet in ignition.

Neither of two keys function to remote-unlock or lock doors, and neither key opens front or rear hatches.

Try this: insert key into door lock, turn it to unlock position and hold it there, then press the unlock button while holding the key in the turned unlock position.

it should be fine for next time after you start the car.
