2003 civic. i have no key fobs for the car. Can I get an email key fob and do something with the ignition key and some sequence to reprogram (like other cars) or is getting a new key fob a dealer visit?

thanks in advance.

warning lights, yes, still can't beat 40 mpg.

 

found the answer - can do it myself!

 

If successful, post the process. I have done it on my '99 Z28, but haven't tried on the Civic.

Alos, how much did you pay for the replacement fob on eBay?
