Car Immobiliser Croydon – Mobile Fitting Across CR Postcodes

Croydon is one of London’s largest boroughs, and its parking is as varied as its streets – on-street parking in Thornton Heath and central Croydon, driveways in Purley, Sanderstead and Coulsdon, and vans parked overnight across CR0 and CR7. LockCar fits hidden relay immobilisers for cars and vans across the borough, with a mobile engineer who comes to you.

Why car owners in Croydon are adding an immobiliser

Most cars stolen today are taken electronically rather than by force. Keyless entry can be fooled with a relay attack, thieves can inject commands into the car’s data network, and new keys can be programmed through the diagnostic port. The factory immobiliser trusts the car’s own electronics, so these methods get past it – often without a scratch on the car.

Keyless SUVs are a frequent target in the leafier southern neighbourhoods, while vans parked on the street face a different risk: theft of the vehicle and the tools inside it. The A23 Purley Way, the A232 and the A212 provide quick routes across south London and towards the M23 and M25, so a hidden immobiliser that stops the engine starting is the most effective first line of defence.

How keyless car theft works – and how an immobiliser stops it

In a relay attack, one device near your front door picks up your key’s signal and a second device next to the car replays it, so the car unlocks and starts. A LockCar immobiliser adds a hidden relay in a circuit the engine needs. It only closes when your separate LockCar tag or app is present, so relayed signals, injected commands and newly programmed keys are not enough on their own.

Parking and security tips for Croydon

For vans parked on the street overnight, combine a hidden immobiliser with good deadlocks and remove tools where you can. For keyless cars on driveways, keep keys in a Faraday box away from the front door. If you park near a tram stop or station during the day, remember a key pouch at home does not protect the car there – an immobiliser does.

If your vehicle is ever stolen, report it to Metropolitan Police on 101 (or 999 if the theft is in progress). Our guide on what to do if your car is stolen walks you through every step, and our car theft prevention guide explains each theft method in more detail.
