Top Digital Key Relay Attack Protection Smart Ring Car Immobiliser Keyless Theft
Keyless relay theft can take under a minute: one device near your front door, one next to the car, and the factory system thinks the key is present. The LockCar DK3262 adds a second digital key the relay box cannot answer. Even if the car has been opened with a relayed signal, the engine stays blocked until your paired smart ring is found.

Relay attack protection you wear: a smart ring as your second digital key
A relay box copies the conversation between your key fob and your car, not the key itself. That is why the LockCar DK3262 does not rely on the fob at all. It waits for a second digital key, your paired smart ring, before it lets the engine run. The relay kit has nothing to answer with, so the car can be opened but not driven. For you, the routine stays the same: wear the ring, get in, press start.
- A second digital key that a relay box cannot copy
- Engine authorisation kept separate from the keyless entry system
- Your smart ring is checked every time the ignition comes on
- No keypad, no code and no extra fob added to the cabin
- Works offline, with no internet or mobile signal needed
What a relay attack looks like when a DK3262 is fitted
Two thieves work together: one holds a relay device near your front door, the other waits by the car. The factory system is fooled into thinking your fob is present and the doors unlock. With the LockCar DK3262 fitted, the next step fails. The engine stays blocked because no paired smart ring is in range, and if nobody is identified within 30 seconds of the ignition going on, the car’s alarm sounds.
- Doors may open with a relayed signal, but the engine stays blocked
- 30 second window before the car’s alarm is triggered
- No LEDs or beeps to tell a thief that a second lock is fitted
- Hidden in a different place in every car
- Arms itself automatically every time you park
Why a keyless car needs a second digital key, not just a signal pouch
A signal-blocking pouch only helps on the nights you remember to use it, and a spare fob left in a drawer can still be relayed. The DK3262 protects the car itself. Its engine block sits outside the factory key system, so whatever happens to your fob signal, the car will not drive away until your paired smart ring is recognised within the range you set.
- Protection built into the car, not dependent on your habits
- Engine block independent of the factory key system
- A spare fob at home cannot start the car on its own
- Detection range adjustable from 1 to 5 metres
- Manual backup control in the LockCar app
Relay theft protection that stays out of your way
Security that is awkward to use soon gets switched off. The DK3262 avoids that by working in the background: it recognises your smart ring as you approach and releases the engine without you touching anything. Park up and walk away, and the block is back in place. The LockCar app is there when you want to arm or disarm by hand, or lend the car using valet mode.
- Hands-free release as you approach, blocked again when you leave
- Valet mode for services and car washes
- Authorisation log in the app for every start
- No subscription and no monthly fee
- 12 month UK warranty with lifetime app support

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.
