Narrative:

On takeoff in lax on runway 25R we got a door caution light around 100 kts. I was the pilot monitoring and cancelled the light and said door light (looking back I don't know if I said it loud enough for the captain to hear) the captain performed a rejected takeoff. We both performed our immediate action items and cleared the runway. We told the tower that we did not need assistance; ran the QRH; talked to the flight attendants (the door light had gone out and we had the fas re-check the main cabin door handle); and checked the brake cooling charts. We waited about 13 minutes and took off uneventfully.
