I purchased a used 2012 Grand Cherokee Altitude edition this past weekend, and before purchasing it, I sent the VIN number to Jeep and obtained the build sheet. The build sheet shows the remote-start option was installed on this Jeep.
However, the previous owner only supplied one key fob, and the only enabled button on the key fob (excluding the unlock/lock/panic buttons, of course) is the button for popping the rear window. This left me wondering – where is the button for the remote start? The only explanation I can come up with is: perhaps the original owner lost one (or both) of the original key fobs and purchased a new one, but forgot to make sure the remote-start button was included/activated.
Anyways, after a little searching, I came across this post (found here

Apparently, even though Jeep removed that functionality from the fob (and its icon on the corresponding fob button), it still works if you put "a little metal disk" under the corresponding fob button.
If the remote start module is already installed, could you access remote start by simply putting a little metal disk under the corresponding fob button?
Does anyone know the answer to the question I've highlighted in yellow? If I were to pop open the key fob and insert a metal disk under the top-right button where the remote start function is typically located, would my remote start work? Or does it require additional programming? Again, my assumption that the Jeep already has the remote-start module is based off the build sheet, which I would hope
is correct, given that it came directly from Jeep.
I figured I would try asking here before I go popping the fob and moving the metal disk around.
