Speed Induced Auto Lock

[coasternd]

Hello All!
So I have had my 2010 Yaris 5Door for a year this past week, and over there year I have slowly noticed features that my old Dodge had that my new Yaris doesn't and I kinda miss those features. One I miss the most is how my dodge would automatically lock all the doors once I hit 15MPH. Since my Dodge did this by itsself I was used to it, now I never remember to lock the cars doors. Does anyone know of a kit that can be added to the car that will reproduce this feature? Where I can get said kit, and how much it might cost? My Yaris has remote keyless entry and power windows and locks.

Thanks in advance!
