How it works

Two locks on your car.
One app in your pocket.

IMMOSTOP puts two independent immobilisation points on your vehicle that must both be released before it will start — and only your phone can release them. Here's exactly how it protects you, day to day.

The problem it solves

Most modern cars are stolen without the key ever being touched. A relay attack copies your keyless fob's signal from inside your house and tricks the car into thinking the key is present — the car unlocks and drives away in under a minute. A standard alarm or factory immobiliser doesn't stop it, because to the car, everything looks normal.

The IMMOSTOP answer

IMMOSTOP breaks the chain at the one point a thief can't fake: your phone. The engine is held immobilised at two separate points, and the car will only release them when your authorised phone is present. So even with a perfectly cloned or relayed key, the car simply won't move for anyone but you.

1

Professionally fitted

An Autosecureshop specialist installs the two immobilisation points, hidden in your vehicle. Clean, discreet, with a parts & labour warranty.

2

Paired to your phone

You set a private PIN and pair your phone once in the app. That phone — and anyone you authorise — becomes the key.

3

Protected, automatically

From then on it just works. Walk up, it disarms. Walk away, it arms. No buttons, no remembering.

What you get, every day

Dual immobilisation

Two independent cut points, not one — far harder to defeat than a single immobiliser or an alarm on its own.

Beats keyless & relay theft

Cloning the key isn't enough. The car stays immobilised until your paired phone releases it — the one thing a thief can't copy.

Automatic proximity mode

Your car disarms as you approach with your phone and re-arms the moment you leave range. Nothing to open, nothing to press.

Works with the app closed

Proximity runs quietly in the background — you don't need to open the app. A small shield shows at the top of your phone while it's protecting you.

Keyring fobs

Hand a small keyring fob to a partner or family member for hands-free disarm — without sharing your phone or your PIN.

Parked-car location

The app drops a map pin where you left the car — handy in big car parks or an unfamiliar street.

More than one car

Run several vehicles from the one app and switch between them. Each car keeps its own records and its own protection.

You stay in control

Only your PIN releases the car, and we never email it. Lose your phone? Set it up again and you're straight back in — you're never locked out of your own vehicle.

Already have an older app-controlled immobiliser?

If you've been left with a Bluetooth proximity immobiliser whose app no longer works, IMMOSTOP can reactivate it — pairing it to the IMMOSTOP app so your existing hardware is protecting your car again, no new unit needed.

Send your device details for a compatibility check and we'll tell you if yours can be reactivated.
