Butch have you tried running the vehicle with the window down and simply pushing on the door unlock switch?
Have you actually went to Kia and asked about having an extra key coded to the vehicle? Like actually done it? I've done many remote starts over the years, no unfortunately not what you're driving, but I've never heard of manufacturer that limits you to only two keys..
Hope you get it working the way you want it to. Mine is the lower end Borrego without the smart key so I can't do a write up about it.
1 - Rolled windows down
2 - Started vehicle
3 - Closed door, reached in window, locked the vehicle (can't lock driver door with vehicle running and door open)
4 - Put FOB about 50 feet away, and went back to vehicle and tried pushing the door button. Vehicle would not do anything.
5 - Got FOB, went back to still running vehicle, walked to door, pushed door button (not FOB button), and Borrego just does a long beep at me. Will not unlock the vehicle. FOB is also dead, and will not unlock the vehicle, nor do any other function while vehicle is running.
6 - Had to reach into vehicle and manually unlock door, so I could then reach over and shut it off.
Kia can only code 2 FOBS for our vehicle. Service manager verified it for me first, and when I didn't believe him 100%, I started investigating on the web.
This 2 FOB limit is a limitation by the manufacture of the security FOB system (Siemens-VDO). There is documentation on the web about it. Search the web for the FCC ID on the back of one, and you can find the Siemens documentation in a few places.
Very stupid design, which is why in the link I gave, I was trying to find out if there was a way to clone the ID in one of my existing FOBs. A cloned one would give me another spare to keep somewhere safe. There are a few companies that already make the cloning hardware for some other key systems. I'm just hoping that at some point they get around to making something for the Siemens-VDO system.
If there is a way around the 2 FOB limit, Kia (nor Siemens) is letting on about it, even if it would mean they could sell more of those nice expensive FOBs.
The guys over at 12volt are pretty much to go-to guys when you have questions. They are part of the group that makes the data systems that connect to the data control lines in most new vehicles now. Basically, if it is controlled through a digital data command, then their boxes can replicate it and do it from a FOB. Problem is when the data is encrypted, like with my FOB. No way (so far) to fool the auto into thinking it is talking to the FOB, not a 3rd party box. They cracked the encryption for Dodge recently, which opened up a whole new world for them and Dodge owners!
I'm open for suggestions though! Anyone else run into this crap with their Borrego Limited yet? I'm especially interested in someone coming up with a way around the 2 FOB limit.
