Update on pricing - I lost my 2nd FOB somewhere in the house and I'm sure I'll find it after I get the new one. Local dealer quoted $225 for FOB and uncut key, $37 to cut key and $47.5 labor to program the unit. Looks like about $311 to replace a lost FOB. Bummer

 

Here is what I have done (hope it never comes in handy) with my fobs.

Each one has a little plastic tab on the ring with my cell phone number on it .
That way, no one knows my name or address but can call me if they find my fob somewhere to let me know they found it.

I also keep a HUGE three dimensional keychain on each so that they are not easy to misplace in the house!
