Protect your car.
Stay in control.
A purpose-built immobiliser that hides behind your dash. No app, no GPS or monthly fees.
Modern thieves don't pick locks.
They sneak in through your back door and grab your keys. They relay your fob signal from outside your bedroom window. They plug a coder into the OBD2 port and drive away in seconds. None of it works if the starter circuit needs a code — and the cabin alarms when they try.
Two cuts.
A code in your head.
Hover or click each step to see what happens between turning the key and the engine actually starting.
Tape, tuck, done.
Four steps. all-black harness, full wiring diagram for your car. Most auto-electricians finish in less than 2 hours. Bring your own 12V horn/siren — any will do.
Pick your setup
Manual or automatic? Stop/Start? Pick the right diagram from the manual. Decide where to install 1–3 hidden buttons — more buttons makes the unlock sequence harder to bypass.
Hide the units
StarterStopper ECU and Alarm ECU live behind the dash. The two relays live in the engine bay. Smaller than a deck of cards — pick spots a thief won't reach in 60 seconds.
Splice the circuits
Cut the wire from the starter relay to the starter motor solenoid and splice in the StarterStopper Relay. Splice the Alarm ECU into the start signal. Wire the Alarm Relay through a 20A fuse to your horn/siren.
Set your sequence & test
Turn the key and press your hidden button(s) momentarily within 7 seconds. Skip the sequence and a silent countdown triggers the siren for 30 seconds. Mistype? Press the right combination and it stops.
Pick your kit.
Two units. Same philosophy. The right one depends on what you drive and how loud you want it to get.
The original. Two cuts, one code, zero electronics on your phone.
StarterStopper Alarm can use your existing vehicle horn or another loud output. Horns are not provided.
Will it fit your car?
Pick your make, model and year. We'll tell you in seconds.
Can't find your car?
Everything, nothing extra.
You don't need to source a single connector. Open the box, follow the diagram, install in an afternoon. Alarm version: bring your own 12V horn/siren — any will do.
