Unlocking a 2004 Honda Civic Radio and Setting the Clock

A week or so ago, my wife’s car broke down. The pully on the A/C compressor pulley wobbled and seized, so not only did her 2004 Honda Civic have no A/C, it smoked under the hood from the belt rubbing against the belt. So I had some work to do, and in the course of the repair I had to disconnect the negative battery cable because of reasons (and if you must know, it’s because I had to move the alternator out of the way, and in doing so I started sparking things. Safety second, I guess).

The thing is with Honda, or at least this generation of Honda Civics is that if you disconnect the battery, you end up locking the radio. Some sort of antitheft property that ends up only annoying people who work on them and disconnect the battery.

Fortunately, Honda maintains an online database of the unlock code - you just need the VIN (Vehicle Identification Number) and radio serial number. This online database is at https://radio-navicode.honda.com/.

While I didn’t record fixing the A/C - I needed to fix it as soon as possible - I did video myself unlocking the radio and setting the clock. Remember, my wife’s car is a 2004 Honda Civic. However, the below videos should be applicable to the following years:

  • 2001 Honda Civic
  • 2002 Honda Civic
  • 2003 Honda Civic
  • 2004 Honda Civic
  • 2005 Honda Civic

In fact, it’s probably applicable to Civics outside this year range, as well as other Honda models (e.g. Honda Accord, Honda CR-V, Honda Fit, Honda Odyssey, Honda Passport, Honda Pilot, etc.)

    Thanks Joseph for your detailed explanation but in my case it does not work because the app used https://radio-navicode.honda.com/ is only for cars of US. I bought my car in Venezuela. Can you help me to unlock my radio? The information related my car is: VIN: 93HES16904Z150547 Serial: 40155311 Error of the App: The VIN you entered is not valid. Please verify the number and enter it again. Valid VIN numbers use the letters A-Z and numbers 0-9, except for the letters I, O, and Q

    Thanks in advance for your help!

    Emilio
