Anti theft car immobiliser that turns your smartwatch into a second key
Your factory key still opens the doors, but on its own it no longer starts the engine. The SMART-IC3262 waits for a second confirmation from the smartwatch on your wrist and only then lifts the engine block. For UK drivers it means an extra layer of protection with no change to the way you get in and drive.
- Factory key and paired smartwatch together release the engine
- No keypad, code or tag added to the cabin
- Your watch is recognised automatically as you get in
- Detection distance set by you, anywhere from 1 to 5 metres
- Pairing and settings handled in the LockCar app

How the hidden engine block works on a normal UK day
Think of the school run, the commute or a quick stop at the shops. You unlock the car, sit down and press start as always, and the engine turns over because your watch has already been recognised. Park up and walk away, and the engine block returns on its own once the watch leaves the range you chose.
- No button presses or routine to learn before a journey
- Engine block returns automatically when you walk away
- Works the same in a car park, on the street or on your drive
- Nothing to switch on or off by hand, unless you choose to in the app
- Passengers see and hear nothing different

Why a hidden immobiliser beats a visible deterrent
Steering locks and flashing LEDs tell a thief exactly what to defeat. A hidden engine block tells them nothing. The SMART-IC3262 is fitted out of sight in a different place on every car, so a thief who gets inside has no idea why the engine will not start and no quick way to find out.
- No LEDs, beeps or visible parts in the cabin
- Installation point changes from car to car
- Does not show as an extra ECU during a routine diagnostic scan
- Relayed or cloned keys may open the doors but cannot start the engine
- Car alarm sounds if no authorised watch is found within 30 seconds of ignition

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.
