My engine won't start after i got my car detailed

What is your question?

Hi i had my car detailed on Saturday. They cleaned the interior and shampooed the carpet. The key was left in the ignition - the car wasn't running - but all the doors were left open for aprox 2 hours while they worked inside. Then the alarm came on and lock down the car. We could not get the engine started. I could use the key to lock and unlock the door, open and close the windows but that's all i could do. What would have cause this to happen? Thank you. Sheila
