i had the contact in one of my key fobs break and am about to fix and solder it.
This got me thinking about new key fobs remotes. I wonder if other GM fobs could be used with our HHRs.
In particular, i was wondering if a camaro folding key and remote could be cut and programmed for our cars.
Any thoughts?

 

The camaro folding key uses a sidewinder type key blade, a keyblade in our HHR keyway would have to be fitted. While the transponder for the Camaro and HHR both say circle+, I was told by a Strattec rep that the transponders are not interchangeable. I don't know for sure but the remotes are probably not interchangeable either.

Having said all that, I have seen aftermarket remote head flip keys on Ebay (I have not seen one specifically for HHR but I have not looked for a while).
