Smart car immobiliser built around a device you already own
A smart immobiliser should make security easier, not add another gadget. The SMART-IC3262 uses your existing smartwatch as the authorisation key, pairs through the LockCar app and runs entirely offline once it is set up.
- Uses your existing smartwatch as the key
- Pairing and setup in the iOS or Android app
- Runs offline after setup, with no data plan needed
- Encrypted connection between watch and immobiliser
- No keypad, code or extra tag in the car

Smart features that go beyond simply blocking the engine
Blocking the engine is the core job, but the SMART-IC3262 also covers the situations where ordinary immobilisers fall short, from a car taken while the engine is running to a remote start that should not disarm the security.
- Anti-hijack: progressive engine block if the car is taken while running
- Motion detection blocks the engine if the owner has not been authorised
- Valet mode for garages and car washes
- Authorisation log in the app
- Low standby current, shutting down when the car sleeps

Relay attack block for UK keyless cars
Relay attacks are fast and quiet, and keyless cars across the UK are the main target. A smart immobiliser changes the outcome: the doors may open, but the engine will not start until your paired smartwatch is recognised.
- Relay attack: the doors may open, the engine stays blocked
- Key cloning: a copied key cannot authorise the start
- Alarm after 30 seconds of ignition without a recognised watch
- Hidden install with nothing to find in the cabin
- Compatibility checked from your registration before purchase

Smart release at the distance you choose
Tell the immobiliser how close your watch has to be, anywhere from 1 to 5 metres. Inside that zone the engine is released automatically; outside it, the block goes back on without any action from you.
- Adjustable detection range of 1 to 5 metres
- Automatic release as you approach or sit down
- Automatic re-block when you walk away
- The app remains the master control for manual arming
- No subscription or monthly fee
Technical data








Frequently asked questions
Will a car immobiliser void my manufacturer warranty?
No. The SMART-IC3262 is an add-on security device that does not reprogram or modify the vehicle’s factory software. Fitted correctly by a professional installer, it can be removed again, so it should not affect the manufacturer warranty.
Will the immobiliser drain my car battery?
No. The immobiliser only works when the car is awake. Once the vehicle is switched off and goes to sleep, the unit shuts down too, so it does not sit draining the battery while the car is parked.
Can a thief find and bypass it?
There are no LEDs, no beeps and no keypad in the cabin, so nothing tells a thief that a second lock is fitted. Every installation is hidden in a different place, and with no standard fitting point, finding the block is impractical in the time a thief has.
What happens if my phone is dead or there is no signal?
The car never depends on your phone. The immobiliser works completely offline: no internet, no mobile signal and no subscription. It releases the engine as soon as it recognises your paired smartwatch, and the app is only there when you want to arm or disarm it by hand, or change the settings.
How close does my watch have to be?
You choose. The detection range is adjustable from 1 to 5 metres, so you can set the car to release as you walk up to it, or only once you are inside.
What happens if someone opens the car with a relayed or cloned key?
The doors may open, but the engine stays blocked. If no authorised smartwatch is identified within 30 seconds of the ignition being switched on, the immobiliser triggers the car’s alarm.
Do I have to press anything or remember a code?
No. There is no PIN sequence, no keypad and no extra fob on your keyring. Wear your paired watch, get in and start the engine as you always have.
Can I still control it myself?
Yes. The LockCar app lets you arm or disarm the immobiliser manually at any time, and it is where you pair your watch and adjust the settings, including the detection range.
