Vehicle security with phone app control, background proximity mode and a parked-car map pin.
Two immobilisation points controlled by one device through one straightforward app.
Proximity mode recognises your authorised phone nearby and automatically re-arms when it leaves range.
Requires compatible phone settings and permissions.
A map pin helps you find your way back to your parked vehicle.
Clip an IMMOSTOP keyring on as a second, always-with-you key — so a flat phone never leaves you locked out. Choose a USB‑C rechargeable beacon, or — coming soon — a sleeping proximity tag that sleeps for long battery life and wakes with a quick double tap.
If your phone battery dies, you’re not stranded. Plug the keyring beacon into the car’s USB‑C port — IMMOSTOP recognises it and lets you start and drive. A backup key that’s always in your pocket.
Every handshake is encrypted and rolling, so your signal can’t be sniffed, cloned or relay‑attacked the way ordinary keyless fobs are. Your keyring stays yours.
Our IMMOSTOP sleeping proximity tag will sit dormant to save its battery, then wake the instant you double‑tap your pocket — hands‑free, with nothing to charge or remember.
Your car’s key can be whatever you already carry. Today it’s your phone and a keyring fob or tag — and coming to more devices soon: iOS, your smartwatch and Bluetooth rings.
Every board makes its own random key. No two cars share one, and there’s no master key or backdoor.
The tag answers the board with an AES‑128 challenge — the same class of encryption banking uses. The key is never sent over the air, and it can’t be cloned with a cheap copy fob.
Once paired, nobody can re-pair it at the car. Change your PIN anytime in the app — any old or shared one stops working the instant you do.
Lost your phone? Your recovery code gets you back in, then changes so it can’t be used again.
Lose a keyring fob or tag? Block it from the app and it can never release your car again — your phone is always the master.
Add a partner or family member with driver-only access — they can arm and disarm, but can’t change settings, add users or remove yours. You stay the admin.
Handing the car to a garage, MOT or valet? Switch on service mode from your phone so it starts without the key — and only you can turn it back off.
Signed, checksum-verified firmware reaches the immobiliser over the air — your security keeps improving without a trip to the garage.
Tags that sleep to save their battery and wake with a double-tap — longer life, and nothing broadcasting for a thief to listen for.
Every fit is done by an Autosecureshop specialist and comes with an installation certificate and a parts & labour warranty — proof for your insurer.
The real IMMOSTOP app — see your vehicle's status at a glance and control it from your phone.
IMMOSTOP V1 is our own immobiliser hardware — designed and supported in-house. It also works with older “blue” Bluetooth immobiliser systems, so if your car came with a Bluetooth immobiliser that was left without support, IMMOSTOP V1 gets you a working app and full control again.
IMMOSTOP V1 boards are designed and backed by us — not a third party that can vanish and leave you stranded with dead hardware.
Already have a Bluetooth immobiliser fitted? IMMOSTOP V1 works with those older systems too, bringing orphaned setups back to a modern, supported app.
Unlock the board once, then add as many authorised phones as you need — drivers, family and your keyring beacon.
Unlocking your immobiliser is a single payment per vehicle, with no yearly licence fee to keep it working. Optional extras — GPS tracking, remote feature updates and add-ons — are available separately whenever you want them.
Vehicle Security Specialists based in the West Midlands, providing nationwide mobile installation through our own team.
A professionally fitted immobiliser cuts your theft risk — and some insurers reward that with a lower premium. It varies by provider, so always check with yours. Either way, you’ll have proof it’s properly fitted.
When your immobiliser is registered, an installation certificate is generated automatically — linked to your name, the vehicle VIN, its warranty and your paired phones and tags. Solid proof it’s professionally fitted.
Dual, phone-released immobilisation makes your car a much harder target — exactly what insurers weigh when pricing cover.
Installed by Autosecureshop’s own specialists — not DIY. A documented professional fit is what insurers and future buyers want to see.
Insurance savings vary by provider and aren’t guaranteed — always confirm with your insurer. More detail: does a car immobiliser lower your insurance?
