I have two Viper key fobs that were used on a 2009 Honda Fit which is now out of commission. How do I know if these remotes are compatible to the 2011 HHR and then if they are, suggestions for getting them program???

 

They are not unless you have a Viper system in you car. Viper is an after market brand.

The fob must have the correct FCC registration number on it to work.

 

Thanks, that kind of what I thought. It is a Viper key fob, but I don't think the HHR has a system that matches. Oh well, wishful thinking!
