Frisco is the van's northernmost city and the one where the tools in the van earn their place. The subdivisions off Preston, Legacy, Eldorado and Main hold BMW X5s and X3s, Mercedes-Benz GLEs and GLCs, Audi Q7s and Q5s, Lexus RXs and GXs, Volvo XC90s, Genesis GV80s and Teslas beside them, most under five years old, most leased or financed, and all built so that a battery, a key or a module from outside the dealer's system does not work until a tool tells the vehicle to accept it.
That is the work a parts store cannot do and a neighborhood shop usually cannot either. A new AGM on a BMW must be registered and its capacity coded or the vehicle overcharges it and keeps its stored faults; a spare key for an Audi needs an online session with the manufacturer; a body module on a Mercedes-Benz must be coded to the VIN and matched to the immobilizer. The van carries the brand-level tools for each and does the work in the garage, which is the difference between an hour at home and a day at a dealer on the Tollway or in Plano.
Frisco is also families and three-row SUVs: the Highlanders, Pilots, Telluride and Palisades, Tahoes and Expeditions that carry children to Frisco ISD schools and to the sports complexes along the Tollway. Those need batteries after three summers, brakes after a year of the Tollway commute, oil to the right specification, and keys for new drivers. HOA driveways are wide and flat, and the van works in them with a mat and a sealed drain container.
The Star, Hall Park, Frisco Square and the office developments along the Tollway and Legacy add commuter vehicles in garages from eight to five, where a battery, a diagnosis or an oil change is done beside the vehicle while the owner is upstairs. The booking reply confirms the garage clearance and the key arrangement before the trip.
