Searched and searched. Cannot seem to find the correct part number for 2014 ELR 5-button keyfob replacement. One of mine went through a Maytag heavy cycle and is toast.
Well I tired pairing a loaner CTS-V key I had when the ELR was in for service and I picked up/dropped after hours for funsies and it didn't work. I assume they are different frequencies.The part number is unique to the ELR, but I would imagine something else would program to the car. You could always pick up a cheap one on eBay and give it a shot.
