Radio will not work after battery change.

Asked by Jan 12, 2016 at 11:48 AM about the 2011 Honda CR-V

Question type: Maintenance & Repair

I had a new battery put in my CRV and now the radio/navigation/backup camera will not work. It is asking for a security code, which I do not have. How do I obtain this?

some will come back on with the key left in the on possition for 10 min.Try turning the ignition key to run position so the dash lights come on for ten minutes to see the radio recognizes the VIN so it works again.The process for finding out a car radio code differs from one make to the next, but you’ll generally want to start by looking in your owner’s manual. If you bought your car used, the previous owner may have written the number down in the manual, and some manuals actually have a place to do so. If it isn’t there, then you can check the OEM website or contact your local dealer, although you may end up having to pay a local shop or online service to look the code up.

Some Hondas and Acuras have a label with this code on the side of the glove compartment. Open it, do not look inside where you store your vehicle's documents, but look on the side of it. The picture is for illustration only, may not be you vehicle. I just found it online to illustrate where the location of the label could be. I hope this helps!
