Honda Odyssey Anti-Theft Systems

Hi,

We have a 2003 Odyssey. Over the weekend the factory installed alarm began going off spontaneously when the car was locked (not just when armed). I drove the car about 100 miles and this only delayed the return of the problem.

Can anyone provide insight as to what is causing this BIG annoyance? I tried to find a "problem" area of this site to post this but all appear to be "read-only."

I have a similar problem. I have the code for my 99 Civic but when I enter it I keep getting error 1,2,3,...
The code is the one that came with the car. Suggestions?
thanks

How do I get the radio to ask for the code?

Whenever someone does something to the transmission of my Honda Odyssey the radio gives me a blinking light like someone tried to steal it. The problems is all I get is the blinking alarm light but no "code" message so I can input my code. This happened a couple of years ago and the mechanic was able to help me on the phone. However he is no longer there and everybody else suggests the radio is bad and I don't remember what he told me.

Radio code and radio replacement

I followed below link to find out how to open the dashboard of honda odyssey and remove radio out of it. Below link has drawings and instructions to follow.

I followed step by step and successfully opened dashboard and removed radio out to find its serial number.

If you do not have radio code, Honda Customer service can help. They need your Vehicle Identification Number or VIN(it is on the top of driver side dash board) and radio serial number(SER). I have VIN but no SER. Honda directed me over phone to look inside glove box for any stickers pasterd with radio serial number. I have one but that did not work. Then they asked me to press 1 and 6 buttons at the same time and then switch on radio power. Before I did this, I need to put key in II position and battery negative terminal disconnected. The idea is to get serial number on the radio screen. For my luck, the SER number is not coming up on the radio screen. Then, I was told to go to dealer to get this radio code who can get serial number of the radio somehow. My friend told it costs $120. I am on tight budget and could not afford the cost.

I got my tool box out and sat near dashboard and followed instructions given in above link. I safely saved all the screws and remembered in writing what plugs I unplugged and their color and their location. Finally, I removed the radio unit out and found a yellow sticker below the radio unit which has the serial number on it with prefix, SERIAL No.
For my surprise, I see a hand written 5 digit code also there which I guessed as radio code. I put everything back without leaving a single screw outside. Connected negative terminal of battery. Started engine and engine started. Good relief that I did not break anything. Then nervously entered the code, yahoo!, it worked. Radio turned on with a music in some FM channel.

You may not have to do all this. Call Honda CS first at their customer service number: 1-800-999-1009 and if they advice you to go to dealer at your own cost, try my steps. Good luck!
