Carjacking Solution:

Phase 1 ask vehicle owners to document their TPMS Sensor IDs in each tire. 95% cars have them. Legislate that tire shops and auto repair shops provide in writing the tpms ids in each tire to owner. Have community tpms ids scanner events . No privacy concerns as owners hold the information until reported after car stolen.

Phase 2 with FFRDC help to modify 315 MHZ receiver boards in Residential Garage Door Openers to feed received IDs to query stolen car database with these IDs. Install in patrol cars.

Every garage door opener listens 24/7 data packets at 315 MHz. Every tpms sensor pinging in every tire of 95% cars on road are received within range 50-80 feet. The firmware in circuitry program not to act on different packet types and garage door packets with wrong hash values (learn button sync hash values )

If most patrol cars had 315 MHz receivers listening for tpms Id packets that could immediately notify patrol officers when stolen cars within range, with enough patrol cars enabled and moving, a sufficient coverage can be assured. Such listeners could be added to traffic cameras too!

Range depends on power of receivers, even simple garage door receivers work at least 50 feet as drivers can signal door opening while away from home.

Receivers would do web service calls on cell data to existing national stolen database with these extra attributes on tpms ids provided by owners when stolen report was taken in real-time. Any query hits notify the patrols including car description in their response.

TPMS Sensor ID is 10 characters of both letters and numbers.

A Stolen Car Detection Grid In Our Homes

May sound far fetched. Many new garage door openers are now internet connected, this leads to new possibilities.

Garage door openers are already listening to 315 MHz frequency so with updated firmware, each could forward any received tpms sensor packet ids received in their range to a centralized database via WebService calls with its locations. Each wifi garage door opener becomes a node in a large detection grid. A grid which thieves can not see and avoid.

The centralized database would then query national database of stolen vehicles and report any matches to law enforcement is that location in near real-time. Such detection net the need for municipalities to install listeners on roadways and patrol cars would be optional.

But all this can not happen without Phase 1.
