Digital Key Immobiliser Smart Ring Start Anti Theft Car Engine Block UK Made
A digital key immobiliser does one job: it decides who is allowed to start the car. The LockCar DK3262 is fitted out of sight and recognises one digital key, your paired smart ring. When the ring is nearby the engine can start as normal. When it is not, the engine stays blocked, whatever key or device is used.

How the engine block stops a car being driven away
Thieves open cars in several ways: a relayed signal, a cloned key or a key coded through the diagnostic port. The DK3262 does not care which method was used, because it only checks for your paired smart ring. Without it, the engine block stays in place. Motion detection blocks the engine if the car is moved without authorisation, and anti-hijack cuts the engine progressively if the car is taken while running.

- Anti-hijack cuts the engine progressively and alerts you

Buying security should come with someone to call. The DK3262 has a 12 month UK hardware warranty and lifetime support for the LockCar app. It is fitted by an approved installer, it does not reprogram or modify the car’s factory software, and it can be removed again later, so it should not affect your manufacturer warranty.

Technical data







Frequently asked questions
What is a digital key car immobiliser?
It is an immobiliser that recognises a digital key instead of a code or a separate fob. With the LockCar DK3262, the digital key is your paired smart ring: when the ring is recognised, the engine can start; when it is not, the engine stays blocked. You still use your normal car key as usual.
Can I add a digital key to a car that did not come with one?
Yes. Digital keys are usually found only on new cars. The DK3262 is an aftermarket smart car immobiliser that brings the same idea to the car you already drive. Send us your make, model and year and we will confirm the fit before you order.
Will a digital key immobiliser void my manufacturer warranty?
No. The DK3262 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?
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?
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.
Is my smart ring the only digital key it accepts?
Yes. The immobiliser is paired to your own smart ring. A generic ring, a copied factory key or a relayed fob signal will not release the engine.
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 smart ring. The app is only there when you want to arm or disarm it by hand, or change the settings.
How close does my smart ring 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 smart ring 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 smart ring, 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. It is also where you pair your smart ring and adjust the settings, including the detection range.
What happens if my smart ring battery runs out?
The LockCar DK3262 gives you two ways to authorise the engine: automatically, with your paired smart ring as the digital key, or manually, with the LockCar mobile app. If the ring’s battery is flat, simply open the app and send the manual command to authorise the start. Once the ring is charged again, it goes back to releasing the engine hands-free.
