A GPS Tracker With a Kill Switch Only Works If the Kill Switch Survives Being Found
Searching for a GPS tracker with a kill switch usually turns up two different kinds of product: a plug-in tracker that can't really stop the engine, and a hardwired one where the fine print matters more than the marketing. MooveTrax is hardwired, with the kill switch wired Normally Closed so finding and removing the device doesn't restore drivability.
Plug-in vs. hardwired, and why it matters for a kill switch specifically
A plug-in (OBD-II) GPS tracker connects to the vehicle's diagnostic port -- no wiring, a few minutes to install, and just as fast for anyone to unplug. That convenience is also why most OBD-II trackers don't have a real kill switch: there's no permanent connection to the starter circuit to actually interrupt.
A hardwired tracker is wired directly into the vehicle's electrical system. If it includes a kill switch, that's what lets it actually break the starter circuit on command -- which is the whole point of buying one over a plug-in tracker in the first place.
The wiring detail most listings don't mention
Even among hardwired kill switch trackers, there's a wiring choice that decides what happens if someone finds and removes the device: Normally Open (NO) relays need continuous power from the tracker to keep the starter disabled, so pulling the device restores the circuit and the car starts again. Normally Closed (NC) relays are the opposite -- the circuit is broken by default, and only a connected, powered device holds it together. MooveTrax's kill switch is wired NC, so removing it doesn't help a thief. Read the full wiring breakdown →
Before buying any GPS tracker with a kill switch, ask directly: "If someone finds and removes this device, does my car still start?" For a lot of NO-wired systems, the honest answer is yes.
Who this is for
- Rental and car-share fleets -- Turo hosts, traditional rental companies, buy-here-pay-here lots
- Small commercial fleets -- service vehicles, delivery, company cars
- Personal vehicle security -- anyone who wants real remote immobilization, not just a location dot on a map
Pricing scales with what you need: a $0 software-only tier for Tesla and other factory-connected vehicles (no kill switch, since there's no hardware to interrupt), up through the MT3V tier at $165 + $15/month with the kill switch, remote lock/unlock, and a renter-facing access link.

Frequently asked questions
What's the difference between a plug-in GPS tracker and a hardwired one with a kill switch?
A plug-in (OBD-II) tracker connects to the vehicle's diagnostic port with no wiring -- fast to install, but just as fast for anyone to unplug, and it generally can't include a real kill switch since it has no permanent connection to the starter circuit. A hardwired tracker is wired directly into the vehicle's electrical system, including the starter circuit if it includes a kill switch, which is what actually lets it stop the engine remotely.
Can a kill switch be defeated just by finding and removing the tracker?
On many systems, yes -- if the kill relay is wired Normally Open, it needs continuous power from the tracker to keep the starter disabled, so removing the device restores the starter circuit. MooveTrax wires its kill switch Normally Closed instead: the circuit is already broken by default, and only a powered, connected device holds it together. Removing MooveTrax doesn't restore drivability -- it does the opposite.
Do I need professional installation for a hardwired kill switch tracker?
Yes. Hardwiring into the starter circuit means working with the vehicle's wiring behind the dash, which MooveTrax's installer network handles -- use the installer finder to locate someone near you.
Is a GPS tracker with a kill switch legal?
Yes, on a vehicle you own or are authorized to manage. Remote immobilization should only be used while the vehicle is stationary and safe, and local disclosure laws may apply if you're renting or lending the vehicle to someone else.
