Already got power locks? At least on the QC and CC the hardware is already there and all you need is a programmable FOBIK and a willing Tech.
I bought a refurbed FOBIK for $40 and the local dealer tech did the programming for free. However be careful as if the chip in the FOBIK is not replaced or wiped you will get a mismatch message and it will not program. Not every seller on ebay is reliable.
New FOBIK are $100+ Dollars and some dealers charge $60 just to program FOBIK and cut emergency key + $85 for computer time to add sales code so it could easily add up to more than the aftermarket option at some dealers.
It would be an ideal time to add the MOPAR Remote Starter Kit as it comes with two FOBIK and the price is cheaper than two FOBIK alone. Just make sure they add the sales code for RKE as well as RS.
