The radio does not work
So the Honda radio doesn’t work and it just says “Code.” This can be a bit frustrating. You did take your car to a store and it worked when you came in, but not now. Had something changed in the auto shop and the radio has no blissfully distracting noise? Did you check your battery and / or replace it and everything works fine except that radio? For whatever reason, if your radio has power and it just says “Code”, “Enter code” or anything else along those lines.
It is likely that the battery was disconnected and the person did not know or simply forgot that there is an anti-theft function in Honda radios. Various other brands as well. But fear not, there are several ways to fix this problem. Let me tell you how I discovered all this.
We have a Honda Odyssey that my wife drives most of the time. After several calls that her truck wouldn’t start, I went and jumped her into the driveway or her workplace. I decided to investigate what was going on. Unfortunately I didn’t test anything but did find a loose positive connection on the post and assumed the connection was bad and just not recharging as well as it should.
Then the next day I get a call saying that my wife is stranded at work. I know your alternator is working it would have turned off while driving and would not have allowed the vehicle to continue running so it was not the alternator. There was no problem starting it once I jumped it so I figured it wasn’t the starter. The most common problem would be the battery, I couldn’t find a tester and didn’t want to drive the truck to an auto shop to have it tested. So I took a chance and bought a new battery, group number 24F for this Honda Odyssey which is common for this vehicle.
I finish changing the battery, and it’s about 8pm, and the truck starts off great, I leave it off, and it starts later in the evening as well. I am happy with this and I imagine everything is ready. About the battery problem, I was right, but all was not well. The next morning I get a call from my wife saying her radio doesn’t work, it just says “Code” on the screen and nothing works on it.
Researching this quickly during the day, I found that Honda uses a radio code as an anti-theft measure. The code is on a card that comes with the original purchase of the vehicle, which we do not have. A person can call the dealer with the radio serial number and vehicle identification number (VIN) of the vehicle and ask for the radio code. These are the two shapes I found while looking around.
Fortunately, I came across a site on the Honda website that allowed a person to search for their own code. The VIN and serial number of the radio is still needed, but we’ll see how to find it.
In general, now everything is very good with the Honda Odyssey. I did not know that Honda and other vehicle manufacturers have an anti-theft radio code like this.
Possible Problems and Serial Number Locations
There are a couple of things people should know before they start. First, when entering the code, there are a total of 10 times you can make a mistake before the system locks you. If the system locks it, you must wait an hour with the system on for it to unlock.
Second, if you don’t have the radio code card or radio code yet, you will need to look it up. This is what the main part of this article is about.
For vehicles prior to 2001, you may need to make a service call or activate the radio to gain access to the radio serial number on the label. This label is on the radio, but inside the dash.
If you are having trouble locating the serial number, you can look inside the glove compartment for a yellow label. Press and hold the “1” and “6” buttons on the radio at the same time. This is a good method for any 2001 and later.
Radio code card
The most direct way to find the Honda radio code is from the radio code card. If you have this, the first number is the radio code number. The second code, as in the example, is the navigation code. Having these means that you simply need to enter the code on the radio. Once the …
