Nope. Not on mine.


(Come on folks. If you want to ask a question at least put in some details. We are not mind readers here.)

 

it isnt the right part number for an hhr

That part number may work, it comes back to a fob common to.....

2006 - 2007 Buick Terraza
2008 - 2010 Chevrolet HHR
2006 - 2008 Chevrolet Uplander
2006 - 2009 Pontiac Montana SV6
2006 - 2007 Saturn Relay



If your 2008 LS panel has the AP3 remote start option, it will not work for your vehicle.

 

What about it?

 

If I had to guess, he needs fobs for his HHR Panel, but it seems he's very much into verbal economy.

 

he just needs to call the dealer, give the last 7 of his VI
N and get a part number for the FOB from them

 

Even without AP3 the RS fob will work (and vicey-versey), the contacts are all on the PCB. RS button just combines LOCK+PANIC.
