No it won't, at least according to Chevy lit and the owner's manual, you will only see options on the DIC for options that are installed on the vehicle.

 

But if it's a former rental it could have it but be disabled because of the "hood switch delete" Thus it would show in the DIC but not work without the mod to bypass that

 

Sounds like the wrong fob came with your car. I know I have learned to ask the dealer whenever I buy a used car if it has both sets of keys and fobs. Some years ago when I bought a used Aurora the service dept had a box of extra fobs. They picked one out of a of 'extras' box and then programmed it to my car. Luckily it was the correct fob with the correct button format and since the car had memory seats they were able to get the #2 fob that was missing. I believe with the HHR a standard fob without the remote start can be programmed to allow function of the open/close/panic buttons. Only thing missing is the remote start button. I will say that at first I thought the remote start was a gimmick. I find it useful in our 90+ weather to start the car so the A/C can start blowing as I walk up to it in a parking lot. As I load groceries, etc, the car is cooling and is much more comfortable than if I hadn't started it in advance. I'm not talking letting the car run 10 min, 2-3 min makes a nice difference and not much fuel was wasted.

 

I remote start mine, let it idle til it stops, and start it again!


***** You, Ozone Layer BwaHahahahahahhahahaaaa!

 

how much fuel are ya gonna waste just idling ?

These get great MPGs as is..

 

Like I've been saying, the internals are ALL THE SAME the only difference is the outside shell and which buttons are on it. Any fob from this series will perform every function if paired to the vehicle, it just needs the visible buttons to push. My HHR had the none remote start shell on the fob and was programmed at the Chevy dealer after I bought it, I then was going through the DIC and discovered I had remote start, went back where I bought the car, the dealer, a friend of mine, dug up a fob with remote start. I swapped the interals and in 30 seconds, I had remote start. I also have a trunk release button that's useless but who cares?

 

There is no AP3 listed. Are these codes the options the car came with? If so, where is there a list to decode them? That could come in handy.

Thank you very much. I already printed out the list for future reference.

This was a lot of great info from a lot of folks. Thank you. My HHR was a California rental or fleet car. I think there is a good chance this will work.

My plan of attack: ground the purple wire, and try to remote start with the lock and panic switches. If it works, I will purchase a new fob, and get a new shell for my current fob.

Yes, remote start wastes some fuel, but when the temp is 20 below, and you hop into a completely cold car, your breath fogs the windows. I promise to use it sparingly.
