The key fob itself is a few pieces, one of them is the rubber part with the clickers. This can be purchased off ebay (just the rubber piece with all 7 buttons or selected variations of where the clickers are. They cost around 10 USD, will fit your fobWhere do I find 2013 T&C seven button keyfob enclosures? I've looked around a bit and not found one that's OEM.
Yep, you can buy appcar FCA and you are able to activate a lot of things there, but it costs 50$. On top of the hood ajar sensor, you might want to consider the remote start antenna, which increases range of the remote start. Apparently in 09 dodge didn't install remote start antennas, just the normal wireless key antenna. LuckyI ordered and received new button pads for my fobs, easy switch over.
Now I need to buy the hood switch, and the software and hardware to enable remote start. I assume that all I need to do then is just follow your instructions?
I compared a WCM at the auto wrecker yard to one without, I noticed the spot where the antenna plugs into the WCM, the circuit board has these 5 slots it is soldered into, my WCM has those slots there, maybe it would be as simple as removing that antenna connector and soldering it onto my circuit board?Should work without additional antena
