Can't get 99 Honda Accord out of panic mode. What to do?
 

Last night, my two year old grandson was in my car for a few minutes. When I got in the car and started the ignition, lights flashed and the horn was blowing. We disconnected the battery, but it didn't help. The remote battery has been dead for months. Is there anything he could have done to set it off from inside the car?















Any suggestions would be greatly appreciated.
