Frequently asked questions

IMMOSTOP is a vehicle immobiliser controlled from your phone. It arms itself when you walk away and disarms as you come back, so your car won’t start for anyone who doesn’t have a paired phone or fob. It’s professionally fitted by Autosecureshop.

Both:

• Our own IMMOSTOP immobilisers — the dual-point system Autosecureshop fit new. The app is set up when it’s installed and controls everything from your phone.
• Older blue Bluetooth proximity immobilisers — the ones fitted a few years ago that were left without a working app. The IMMOSTOP V1 unlock brings these back to life (see below).

One app looks after whichever you have.

No. The app is a one-off payment per vehicle in the app — no monthly fees, no renewals. It then works on every phone in your household.

Yes — that’s exactly what IMMOSTOP V1 is for. If you have one of the older blue Bluetooth proximity immobilisers that was fitted a few years ago and left without a working app, IMMOSTOP brings it back to life. A one-off unlock turns control of it back on, on every phone in your household. Your immobiliser still works; it just needed an app that could talk to it.

Not sure if yours is compatible? It’s the small blue unit that armed and disarmed your car from a phone, and came with a blue PUK/registration card with a QR code. If that sounds like yours, get in touch and we’ll confirm it in a minute.

Usually you don’t have to do anything. With proximity unlock on, the car disarms as you approach with your phone, even with the app closed. You can also open the app and press Disarm yourself.

Yes. Your car will always start. The app keeps a secure copy of what it needs on your phone, so an underground car park or a dead spot never stops you driving. When you’re back online it checks in as normal.

Proximity unlock uses a little more battery because it quietly watches for you to approach, and it shows a small notification while it’s doing so. If you’d rather, you can turn proximity off and simply open the app to disarm.

Your vehicle is backed up to your account, so it only takes a minute:

1. Open the app next to your car.
2. Go to Settings → Restore.
3. Tap Email me a restore code and enter the code we send to your email.

Your access comes back to the new phone. The code only works once and expires after 30 minutes.

Don’t keep trying — an older immobiliser locks itself after a few wrong PINs. Open the app and tap Restore — it sends a one-time code to your email and puts things right automatically. There’s no card to keep and nothing to lose.

Yes. On your phone it’s held in the phone’s secure hardware, which can’t be read out. The backup on our server is encrypted and is never emailed or shown to anyone — not even to us. It’s only ever used to talk to your own immobiliser.

No. Your phone answers a new random challenge every time it connects, so recording a connection gives a thief nothing they can reuse. The key itself stays inside your phone’s secure hardware.

On our new IMMOSTOP boards, enter your 14-character recovery code (PUK) in the app on your new phone. The board forgets every old phone and tag, pairs to the new one, and the code changes so it can’t be used again.

Yes. Switch on service mode in the app before you drop the car off. You can set it to switch itself off after a few starts so you never forget, and turning it off never cuts a running engine.

No. Once your phone is paired, the board’s button no longer does anything. New phones and tags can only be added from your phone, with your password. See how we protect your car.

Yes. Share a pairing code from your phone and their phone can disarm the car. If they want the full app on their phone — logbook, settings, tags and the rest — they can unlock it with a small one-off payment, just for your vehicle.

A small fob that disarms your car hands-free by proximity, the same job your phone does — handy if you don’t want to rely on a phone. If one is lost, your installer revokes it and it stops working for good; nothing else needs changing.

No. The only location feature is “Remember where I parked,” and it’s off unless you switch it on. When on, the spot is saved on your phone only — it is not uploaded to us. There’s no journey tracking.

Your certificate and warranty begin when your vehicle is registered in the app. Keep your registration details (plate, make, model) up to date — insurers sometimes ask for the certificate, and it’s available in the app.

Install the IMMOSTOP app, open it next to your car, and it reads your immobiliser. Then tap Unlock — it’s a one-off payment in the app for that vehicle, with no subscription. If the car has locked you out on the PIN, the app restores it with a one-time code sent to your email.

Yes. Spare fobs are available to buy, and your installer pairs them to your car in seconds. A fob disarms hands-free like your phone does, so it’s handy as a backup or for another driver. Lost one? It’s revoked and stops working for good. Ask us about fobs.

Yes. If you fit vehicle security, or you’re holding blue immobiliser stock you couldn’t sell once the original app stopped working, you can become an IMMOSTOP reseller and activate boards for your customers — turning dead stock into working, fitted security. We approve you by email, then you claim your own installer code to set customers up. Request a reseller account.
