Question about 2002 Chevrolet TrailBlazer
If the radio display reads "code" then simply use theradio preset buttons, enter the code in the correct order, and the radio will unlock. If, however, the radio reads "Err" or "Code Err" It's likely that someone has made several attempts to unlock the radio using incorrect codes. In that case you will need to disconnect and reconnect the negative battery cable. This will reset the radio and allow you to enter your code.
If you lost the code, you may retrieve it from https://radio-navicode.honda.com/
The code they gave me was 2246, but I had to add an 1 at the end of it to get it to work, so the end of it was 24461. Yours will be different.

If an audio unit with theft protection is disconnected from electrical power, you must enter a unique code number into the unit or it will not work. This code and the audio unit’s serial number are listed on the anti-theft ID card that comes with the vehicle. If this card is lost, you must obtain the audio unit serial number in order to get the radio code. Some newer vehicles allow you to retrieve the audio unit serial number electronically from the radio. Refer to your owner’s manual for the specific procedure. Some older vehicles (model year 2003 and older) require a visit to the dealer in order to retrieve the audio unit serial number. Once you have the audio unit serial number, you can call Auto Customer Service at (800) 999-1009 or have the dealer look up the radio code.

SOURCE: what is the code?
Most hondas have the code on the vehicle itself for resetting the code once the battery has been disconected or radio removed. Try pulling the glove box out and looking on the inside of the cavity. You should not need a code to remove the radio the alarm should not go off, it is the installation. The radio will not work with any other --vehicle without your specific code, good thieves know this and would rather steal the whole car. "Especially the Honda Accord. Have one in the garage and a 2005 Pilot.

FREE and EASY methods to get your Honda radio UNLOCK CODE. (Dealerships usually charge)
Assuming you don't have the Anti-Theft Code and Serial Number that is found on the credit card sized Anti-Theft Radio Identification Card that comes with the vehicle at the time of purchase and is usually found in the glove compartment....
You have FREE options to retrieve that code by phone or on the internet BUT, the RADIO SERIAL NUMBER is REQUIRED (no matter what). (see bottom about removing ERROR E3)
***IF your Honda was made BEFORE 2001 the serial number MAY not be accessible without removing the radio from the vehicle.***
* TO GET THE SERIAL NUMBER (so that you can get the unlock code)
1. Get something to write with and on (you'll need it to write down the serial number)
2. Put the ingnition key in and turn it until your able to turn your radio on (accessories position).
3. Then turn your radio OFF by it's knob/button (but leave the ingition key in place).
4. Hold down the preset buttons 1 and 6 at the same time.
5. Turn the radio on while pressing down both the 1 and 6 buttons.(***IF your Honda doesn't have preset buttons on the radio then hold down the top part of the 'Seek/Skip' button AND the top part of the 'Change Disk' button instead.*** )
6. Write down the 4 numbers you see first and then 4 more that display. These eight numbers are the SERIAL NUMBER. This is NOT your CODE.
7. Make sure your VIN (Vehicle Identification Number) is handy to get the unlock code. (can be found on your insurance card, driver's side door jam, small plate on dashboard by registration and inspection stickers, etc)
* TO GET THE UNLOCK CODE (using the radio Serial Number and VIN)
1. Go to https://radio-navicode.honda.com/ (YES, it's run BY HONDA and IT'S FREE)
2. Follow on screen instructions (Serial Number and VIN required)
3. Type in the 5 digit code into your radio. This will unlock the radio and return it to a functional state.
1. Call American Honda Customer Relations (800) 999-1009
2. When the automated message starts 'Press 3' for 'Radio and Navigation Codes'.
3. Tell the Customer Service Agent you need your radio code. (They will ask for your name, your radio's serial number, VIN, etc)
4. When they give you your radio unlock code--WRITE IT DOWN and KEEP IT SAFE!
5. Type in the 5 digit code into your radio. This will unlock the radio and return it to a functional state.
* REMOVING ERROR E3
****If you entered too many wrong codes and got an ERROR E3 message displaying you'll need to do an additional step for even the correct unlock code to work.****
Disconnect your negative battery terminal (or pull the radio fuse out if that's easier for you) for 30 seconds then reconnect it and then the radio will say "CODE" again and you can put in your correct unlock code.
So what happened to begin with?

If the power from your battery to the Honda radio is interrupted the Anti-Theft feature kicks in, the radio is rendered inoperable and the screen reads 'CODE'. You must enter in the Anti-Theft Radio Unlock Code (usually 5 digits) to make it operational again. You know that much by now.
