My 2004 honda oddessy - i hit the panic button on key chain on accident. could not get it to shut off, had to drive away. it finally stopped beeping, but a flashing red light on the dashboard kept flashing - a button I ahve never seen flash or light. Got the car home and in park and it went nuts with panic alarm again. There is no alarm on van for security. the panic alarm has stopped, but flashing red light is still blinking. worried this will eat up my battery. please help.

Did you turn the key in the door lock? Or just shut it off with a remote? Try turning the key in the driver's door a few times, lock, then unlock, back and forth a few times - you may be able to reset the alarm that way. Try it, leaving it in each position for about five seconds, and after doing it, try starting the car. No guarantee but it's worth a shot since using the key in the driver's door is the backup for using the remote to arm/disarm the alarm system.

Make sure your hood is shut. I just got my 2002 Honda Odyssey back from the dealer today (90,000 mile check-up - I love my van and will drive it until it dies!) and when I went to lock the van with my remote transmitter, the lights didn't flash and the horn didn't sound. I open and closed all the doors and tailgate and I could hear that the doors were locked, but the security system wasn't working and that is why the lights didn't blink or the horn didn't sound. I walked up to the front of the van to check the hood to make sure it was closed (there isn't an indicator light for an open hood, only open doors) and the hood wasn't shut completely. Once I opened the hood and let it drop to securely shut, I hit the door lock button on the remote and everything worked like a charm! Hope this helps others in this predicament.

have you checked your fuses? the main beam is on a seperate fuse to the head and tail lights this fuse may have blown or have bad connection.

the ignition has two codes,one is in the key.and the other is in the remote(rolling code) the car is telling you that the key is recognised to start the engine but the remote has not sent the correct signal,it will allow you to start the car but is is possible the remotes battery needs replacing,change all keys at the same time,your main keys battery will last about 9 months,the 2nd key about 2 yrs...
