Runway XXL had been closed for maintenance. The airport called to tell me that the runway was open and I amended the IDS to reflect the runway open. However; I forgot to change the runway to open on the ASDE-X. An A310 was inside 1 mile final and the ASDE-X alarmed for the closed runway. I quickly fixed the runway status on the ASDE-X to show it open; as it should be. The alert went away and I allowed the aircraft to land. I now know that I was required to send the aircraft around. There are already adequate procedures for updating the runway status. This has made me realize that I should start using the checklist. This would have been a good time to have some leeway with ASDE-X alerts.
After re-opening a closed runway; Tower Controller failed to note the runway as open on the ASDE-X programming and allowed an aircraft to land after an alarm was broadcasted. The reporter acknowledged his failure to use the checklist.
