I suspect it is cheaper than replacing my 2011 Key Fob. I missplaced my 2nd key and remote start FOB probably within a month of purchasing my Expy. Since 2 keys are required to program the new key, I have to have a dealer program my second key. So that means, $105 for the key, $100 to program and $23 for the Remote start FOB which the factory remote start (which really isn't factory) uses a second FOB now.
Ouch!
Hopefully learned my lesson. I have put it off thinking I will find my second key but it has now been 10 months. I might just have to bite the bullet.
Long story to tell you whatever you pay it is probably cheap compared to what I have to go through.
