Check the fit first, then fit and forget
Every car is wired differently, so we check compatibility before you order. Send us the make, model and year and we will confirm the fit. The module is then installed out of sight by a professional installer, using a colour-coded, pre-terminated loom. After that, day-to-day use is simple: wear your smart ring, get in and start the car.

- Colour-coded, pre-terminated loom for a cleaner fit
- No keypad or screen added to an older interior
- Hands-free start once your ring is paired

Why older cars are easy targets, and how a digital key closes the gap
Many older cars rely only on the factory immobiliser, and thieves have had years to learn its weak points. Keyless models can be relayed and many cars can have a new key coded through the diagnostic port. The DK3262 adds a second check that the factory system does not have. However the doors were opened, the engine stays blocked until your paired smart ring is recognised.
- A second check the factory immobiliser does not have
- Relayed, cloned and newly coded keys cannot start the engine
- Hidden fitting that gives thieves no clue
- Car alarm triggered after 30 seconds without the ring
- Independent of the car’s own key system

Keep your older car, upgrade its security
Replacing a car just to get modern key security is an expensive answer. Fitting a digital key immobiliser to the car you have is a far smaller outlay, and it does not drain the battery, because the unit sleeps when the car sleeps. The LockCar app lets you arm or disarm by hand, change the detection range and hand the car over in valet mode for servicing.
- No battery drain while the car is parked
- Arm and disarm by hand from the app
- Choose how close the ring must be, anywhere from 1 to 5 metres
- Valet mode for garages and servicing
- 12 month UK warranty

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.
