A wearable digital car key that is always on your hand
A digital car key only protects you if you have it with you. Put it in a smart ring and that problem disappears. The ring holds the profile paired to your LockCar DK3262, and the immobiliser looks for that profile every time the car is started. You carry nothing extra, press nothing extra and change nothing about how you drive.

From door to drive: using your digital car key every day
Walk up to the car, unlock it with your usual key and sit down. By the time you press start, the DK3262 has already recognised your ring and released the engine. Park, walk away, and the engine block returns on its own. If you ever want to take over, the LockCar app lets you arm or disarm manually.
- Engine released before you press start
- Engine block returns when you walk away
- Manual arm and disarm in the LockCar app
- No LEDs, beeps or keypads in the cabin
- Works offline, with no subscription

Engine block against keyless relay theft, even if they have your keys
The engine block waits for one thing: your paired ring profile. A keyless relay kit can pass your fob signal to the car, and a stolen key can open the door, but neither carries that profile. The engine stays blocked, and the car’s alarm is triggered if nobody is identified within 30 seconds of the ignition going on.
- A keyless relay kit gets the doors open at most, never the engine
- A stolen car key on its own cannot start the car
- The alarm sounds when no ring is identified within 30 seconds
- If the car is moved without your ring, motion detection blocks the engine
- Anti-hijack protection if the car is taken while running

Your digital car key settings, all in one app
The LockCar app on iOS and Android is where your digital car key is set up. Pair your smart ring, choose a detection range from 1 to 5 metres, look back through the authorisation log and switch on valet mode when someone else needs to drive. A backup PIN is there for the rare day your ring is not available.
- Pair and manage your smart ring
- Release distance you set between 1 and 5 metres
- Authorisation log of every start
- Valet mode for other drivers
- Backup PIN for the days without your ring

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.
