Keyless Relay Theft Protection Car Immobiliser Smartwatch Engine Block Device
In a relay attack, one thief stands near your front door boosting the key signal while another opens and starts the car. With the LockCar SMART-IC3262 fitted, that is only half the job. The engine also needs your paired smartwatch nearby, and that signal is on your wrist, not on the hall table. The car stays on the driveway.

Keyless relay theft protection that works while your key is indoors
Relay thieves do not need your key, only its signal. One stands near your front door while the other waits by the car. The SMART-IC3262 adds an engine block that answers only to your paired smartwatch, so a relayed key signal on its own is no longer enough.
- Protection aimed at relay and signal-boosting theft
- Engine block independent from the factory key system
- The watch stays with you, not on the hall table with the keys
- No change to how keyless entry works for you
- Suits cars parked on driveways and outside the home
What a relay attack looks like with the engine block fitted
The thieves boost the signal and the doors unlock, just as they planned. They get in and press start, but the engine does not run because the second authorisation is missing. After 30 seconds with the ignition on and no watch detected, the car's own alarm goes off.
- Step one: the relayed signal unlocks the doors
- Step two: the start attempt is refused
- Step three: the alarm sounds after 30 seconds with no watch
- No visible device for them to rip out
- The car stays where you parked it
An engine block device thieves cannot see or scan
Professional thieves look for aftermarket security and plug in diagnostic tools. The LockCar device is hidden in a different place on every car, carries no LEDs and does not appear as an extra module during a routine diagnostic scan.
- No lights, sounds or keypad give it away
- Different fitting location on every vehicle
- Not visible as an extra ECU in a routine scan
- Does not reprogram the vehicle's factory software
- Professional installation recommended
Keep keyless convenience and add the missing check
You chose a keyless car for the convenience, and you keep it. The immobiliser works in the background: your watch is recognised, the engine is released and you drive. The only person who notices a difference is the one without your watch.
- Keyless entry and start work exactly as before
- Automatic release within 1 to 5 metres
- Works offline, with no subscription needed
- Anti-hijack protection if the car is taken while running
- 12 month UK warranty and lifetime app support
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.
