Question.

Just picked up an used 2017. I'm looking to get one of these 2018 FOBs - the dealership lost one of the keys and getting me a new one. Would I need BOTH 2017 Keyfobs to program the new 2018 FOB?

So.. Since I just upgraded to the 2018 style keys, I decided to head to the garage and tinker with my 2017 keys to try to make one "stamp size"... I have a decent background in working with small electronics and circuit boards as I used to work in a radio repair shop in the military before I switched jobs.. So I was pretty confident I could cut down some size.



I started off identifying the proximity module and the corresponding paths and equipment to operate the system.. I then trimmed off any excess circuit board with my Dremel and a pair of shears. I then got the magnifying glass out and cut off the little button nubs and made sure they could never be "pressed" again. And finally the battery...The key uses two watch style batteries, the batteries are stacked in parallel, meaning I can just use one to achieve the correct voltage at the cost of battery like being cut in half. I soldered leads to each side of the battery and ran them to their corresponding terminal.



I cut a piece off one of my wifes super thin cutting boards and hid the chip and battery inside the cutout. Wrapped everything in electrical tape, and BOOM!!! IT WORKS! Its the size of a credit card and as thick as 3-4 credit cards. It fits in my wallet with zero issues.



If this holds up for a week or so, I'm going to spend some additional time creating a neater version instead of this super ROUGH one lol. I have plans for a billet aluminum credit card instead of using my wifes kitchen tools lol I will also include much more pics. these are a few pics before I cleaned everything up and make it look pretty. its bed time and I was rushing lol

Two keys are required for a customer to add a 3rd key for security purposes (so valet, etc cannot add a key when they have access to a single key). Dealer can add keys regardless of keys possesed and is the only option if one key is missing.
