Aircraft
The flight left the gate on time. Taxiing out we were instructed to contact Clearance Delivery. We were given a full reroute by ATC due to weather. We were cleared for Takeoff. I; the First Officer; was the pilot flying. AT 90-95 knots a Master Warning light came on and both the Captain and myself determined that the FORWARD ENTRY light is illuminated on the overhead panel. The Captain made the decision to reject the takeoff just prior to the 100 Knots callout being made. I called the Tower to let them know that Aircraft X is rejecting. I followed by asking the passengers in the cabin to remain seated. I also called the flight attendants to confirm that everything was ok in the back. I run the RTO checklist and looked at the brake cooling chart in the QRH. We cleared the runway and proceeded to find a gate to return to. Dispatch; operations; and maintenance were all notified and we were directed to return to a gate. We determined that 30-40 minutes of brake cooling time was required. After troubleshooting the FORWARD ENTRY door problem for a while; Tech Ops personnel decided to remove aircraft from service. We got assigned a different aircraft. The destination noise-abatement curfew was missed due to the delay we had and a decision was made to change the flight destination. The flight was uneventful.
