Wow! Thank you so much!!! It worked.

Thanks for your reply, I think these numbers are the ones you want on that 2005 Honda Civic radio unlock code:

U2203
L5981

I hope you can help, Thanks, again

We have a Honda Civic 2005 we bought used.  When the battery was changed out the radio code was lost and we don't have a record of it.  Could you please help,
When I press numbers 1 and 6 the following appears:

U2203
L5981
6COdE

Thanks
