The threat model

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.

01

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.

02

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.

03

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.

04

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.

The lineup

Pick your kit.

Two units. Same philosophy. The right one depends on what you drive and how loud you want it to get.
