“A systematic review of 16 international studies found that electronic immobilisers as vehicle anti-theft solutions were successful in reducing vehicle theft in 15 cases.”
— Brown, Reviewing the effectiveness of electronic vehicle immobilisation
“Electronic immobilisers lowered vehicle theft rates by about 40% between 1995 and 2008.”
— Economic Journal study on engine immobilisers
Vehicle theft isn’t a myth. In 2024 alone, over 850,000 cars were stolen in the U.S., averaging one vehicle every 37 seconds.
With TSR1‑B or T‑Relay, Topflytech brings the power of proven immobilisers into your fleet—mobilizing safety before theft happens.
Activate via platform or SMS: Send command or wheel ignition logic binds via BLE to GPS tracker.
TSR1‑B (wireless): Discreetly hidden—no wiring to follow.
T‑Relay (hardwired): Installed inline with ignition/fuel circuit—always connected.
Engine stops when no signal: Relay disables ignition—or fuel line—until authorization is restored.
Vehicle immobilised on-the-fly stops thieves instantly
Remaining GPS tracking allows recovery
Deterrent effect: thieves avoid immobilised targets, reducing theft attempts

Connect T-Button with a relay to build a Driver-Authorized Engine Control System:
Driver presses the button before ignition
Tracker confirms authorized BLE ID
If valid, relay closes circuit and allows engine start
If invalid or missing, relay breaks fuel or ignition path
