Austin - I tested it tonight and through various dicking with it - I got it to work. It is an extension of what we have on WK (which never really worked to be honest, well it did (I'm being unkind) but not the same as WK2 but close enough).
So - I found, you have to first check two boxes on the Uconnect system.
1: Settings - Doors and Locks - Personal settings linked to Key Fob. CHECK
2: Settings - Engine Off Option - Easy Exit Option. CHECK
No surprises with checking #1 but it wasn't until I checked #2 that it actually worked.
After these two options checked, then I took Key Fob #1 and started the car. Pressed memory setting 1 on the door panel (my setting), it reconfigured the steering column and seat and then I pressed the Lock option on the key fob. A few clicks and lights flashed and it was set.
Then shut down car, went inside and got Key Fob #2 (Sam's key) and started the car. Pressed memory setting 2 on the door panel (his setting), it reconfigured the steering colum and seat and I pressed the Lock option on his key fob.
Same clicks and lights flash and it was set.
Tested between the two fobs. It works each time.
It did not work however prior to me setting the Easy Exit Option check box.
Anyway, give it a go - it does work.
Oh - the Easy Exit option, works in the same way as our '07 JGC. When the engine is turned off, it adjusts the steering column and also the drivers seat backwards to give you more room to exit (just in case you are wondering what that is).
