Acura Repair Questions? Ask a Mechanic for Answers ASAP
Hello and welcome!
After 10 attempts of entering the wrong code a unlock procedure must be performed. Hook up a battery charger or you can just let the car run for 1 hour with the key in the on position.
After leaving the key on for 1 hour you should be able to enter the code again.
You should have received a card when the vehicle was new. This card has a audio system code number and serial number. Do you have this card?
Ok you have been entering the 5 digit code and the radio has not been replaced.
Try disconnecting the battery cables, touch them together for 2 minutes and reconnect to the battery.
Perform the unlock procedure and enter the code again.
It is a possible issue with the radio.
Here is the procedure to get the serial number from the radio.
1. For models without navigation turn the ignition switch ON, turn the radio OFF. Press and hold station presets 1 and 6, turn the radio ON. You will see the serial number come up on the display. Have a dealer use the serial number to find the code, or use https://radio-navicode.honda.com/. Use the preset stations to enter code, it will be a 5 digit code. If ERR comes up when trying to enter code disconnect the battery for 10 minutes to reset the system and try again.
2. For models with navigation instead of using preset stations 1 and 6 to retrieve code press and hold the top of SEEK/SKIP and CH/DISC buttons, turn the audio unit on and the serial number will appear.
3. For models with navigation the navigation system needs to be unlocked as well. The serial number has to be taken from the navigation unit in the trunk. Give the serial number to a dealer or use the same website as with audio codes. You will get a 4 digit code instead of a 5 digit code, use the tune knob to enter digits.
If you have a error code in the navigation module, fault codes will need to be retrieved to help diagnose the problem.
Did you have a chance to remove the battery cables for 10 minutes.
