The crews that take them plug in, defeat the electronics in minutes, and drive your rig toward a shipping container — while your fob sits on the kitchen counter. The 41.22 kill switch pulls your factory starter relay and drops in its place, so the engine stays dead until you arm it back. Here's how it works on a Land Cruiser. ## Why Toyota Land Cruisers get targeted Land Cruisers have been worth stealing for thirty years, and the theft is rarely smash-and-grab — it's electronic. CAN injection (the "headlight hack") taps the data bus through a fender or headlight to unlock the doors and defeat the immobilizer with no key at all. Relay attacks bounce your push-button fob's signal from inside your house to the truck in the driveway. Either way, the crew is in and gone in minutes, with an export buyer waiting. A kill switch doesn't stop a cloned fob or an injected message — but it does stop the part that drives away. **By the numbers:** ~23x — the 1993–95 Land Cruiser's theft-loss rating vs. the all-vehicle average (HLDI, 1996) · ~60 — LandCruisers & Prados stolen for export in a six-week Australian wave (2025) · 0 — wires cut — our module drops in at the relay ## Pop the relay, drop ours in, the starter stays dead Cloned fob, relay amplifier, or CAN injection — every one of those attacks ends with the thief hitting START and expecting a crank. With the 41.22 module armed, the starter circuit is physically interrupted. The doors can unlock and the dash can light up; the engine still won't turn over. No soldering, no cut wires, and it pops back to stock in minutes. - **Wired Pushbutton ($108):** A hidden pushbutton you mount somewhere only you know. No batteries, ever. - **Wireless Remote ($179):** Two keychain remotes, the easiest install we make. Disarm from indoors; works with remote start. ## A real drop-in install, start to finish Pull the factory starter relay, plug the 41.22 module into the empty socket, mount your switch where only you can reach it, and arm it. The wireless remote is the easiest install we make; the wired pushbutton runs one wire through the firewall. Reverse it any time and you're back to stock. ## Is a kill switch the best anti-theft for a Toyota Land Cruiser? Alarms get ignored. GPS trackers tell you where your Cruiser went — not how to keep it. A kill switch is the only layer that stops the truck from moving in the first place, and it stacks fine with whatever you already run. It's the cheapest "no" you can give a professional crew on a clock. ## Toyota Land Cruiser kill switch FAQ **Will a kill switch stop a relay attack on my Land Cruiser?** Yes — that's the core use case. A relay attack tricks the truck into thinking the real fob is present, so it unlocks and tries to start normally. With the 41.22 module armed, the starter circuit is physically open — the engine won't crank, real fob or relayed one. Toyota's fob battery-saver mode is a good habit on top, but the kill switch protects you whether or not you remembered to use it. **Does a kill switch stop the CAN injection "headlight hack"?** CAN injection unlocks the doors and defeats the factory immobilizer over the data bus. The kill switch isn't on that bus — it's a physical interruption of the starter circuit, so injected messages can't re-enable it. The thief gets the doors open and still can't crank the engine. That's deterrence, not invincibility: the goal is a truck that doesn't start, so the crew moves on. **Does installing it void my Toyota warranty?** It shouldn't. Nothing is cut or spliced — the module drops into the existing starter-relay socket, so there's no permanent modification to point at. And if you ever need to, you can return the vehicle to full OEM stock in just a few minutes by swapping the factory relay back in. **Should I get the wired or wireless version?** Wireless ($179) is the easiest install, ships with two remotes, runs over a year per battery, and lets you disarm from indoors — handy if you use remote start. Wired ($108) is a hidden pushbutton with no batteries to ever think about; it runs one wire through the firewall. Both kill the same circuit. **Is my Land Cruiser 100% theft-proof with this installed?** No product makes a vehicle theft-proof — a determined crew with a flatbed can take anything. A dead starter circuit makes yours a far harder target, so the fast, quiet, electronic drive-away is off the table and most crews move on. ## Make your Land Cruiser the one that won't start From $108 · installs in an afternoon · reversible anytime. --- More: [all vehicles](https://41twentytwo.com/kill-switch-by-vehicle/) · [product & fitment selector](https://41twentytwo.com/product/vehicle-kill-switch/) · [recovery gear](https://41twentytwo.com/product-category/recovery/) *41.22 Inc · Made in Lake Elsinore, California, USA.*
