Which Cars Are Prone to Keyless Theft?

It's about the technology, not the model

The honest answer to which cars are prone to keyless theft is: those fitted with keyless entry and push-button start, because that is the technology a relay attack exploits. This cuts across brands and price points - many modern cars have these systems - so it is more accurate to think in terms of the feature than to single out particular models.

So cars prone to keyless theft are those with keyless entry and push-button start - the technology a relay attack exploits - cutting across brands, making the feature, not the model, the right way to think about it.

What keyless theft is

Keyless theft, or a relay attack, exploits how keyless systems let a car detect a nearby key automatically. In general terms, it targets that convenience to make the car behave as though the key is present. The mechanics beyond this are not something to detail, but the principle is that the vulnerability comes bundled with the keyless convenience itself.

So keyless theft, or a relay attack, exploits how a keyless car automatically detects a nearby key - the vulnerability coming bundled with the keyless convenience, without needing the mechanics spelled out.

Why convenience creates the risk

The feature that makes keyless cars convenient - not having to take the key out - is the same feature that creates the exposure, since the car is designed to respond to a key it senses nearby. This is why the risk is inherent to the technology rather than a flaw in a particular model, and why it affects so many otherwise different cars.

So the convenience of keyless entry - the car responding to a sensed nearby key - is itself the source of the exposure, making the risk inherent to the technology rather than a particular model's flaw.

Protecting a keyless car

The practical protections are about the key, not the model: keeping the key away from the edge of the house near where the car is parked, and storing it in a signal-blocking pouch or container that prevents its signal being picked up. These simple steps address the exposure directly, which is why they are the first line of defence for any keyless car.

So protecting a keyless car centres on the key - keeping it away from the car-side of the house and in a signal-blocking pouch - simple steps that address the exposure directly as the first line of defence.

Physical and electronic deterrents

Beyond key habits, physical deterrents such as a visible steering lock, and electronic measures like an immobiliser, add layers that a relay attack alone does not overcome. Combining a signal-blocking habit with a visible deterrent makes a keyless car a less attractive and harder target, which is the aim rather than relying on any single measure.

So beyond key habits, a visible steering lock and an immobiliser add layers a relay attack alone does not overcome - combining them makes a keyless car a harder, less attractive target than any single measure.

Where a tracker fits in

A tracker does not prevent keyless theft, but it is the recovery backstop: if a keyless car is taken despite precautions, a recovery tracker gives a real chance of getting it back. So the complete approach pairs prevention - key habits and deterrents - with recovery, rather than relying on either alone, which suits the keyless risk well.

So a tracker does not prevent keyless theft but is the recovery backstop if a car is taken - making the complete approach pair prevention through key habits and deterrents with recovery.

Don't rely on a model list

It is tempting to want a list of vulnerable models, but that is misleading - because the risk follows the keyless feature, focusing on a list can give false comfort to owners of cars not on it, and unfair alarm to those on it. The reliable approach is: if your car is keyless, take the keyless precautions, whatever the badge.

So a list of vulnerable models is misleading, giving false comfort or unfair alarm - the reliable approach being that any keyless car should take the precautions, whatever the badge.

Checking your own car

If you are unsure whether your car is exposed, the simple check is whether it has keyless entry and push-button start - if it does, treat it as a keyless-theft candidate and apply the precautions. Your owner's manual or dealer can confirm the features, and a security specialist can advise on deterrents and an immobiliser if you want them.

So check whether your car has keyless entry and push-button start - if so, treat it as a candidate and apply the precautions - with the manual, dealer or a security specialist confirming features and advising on deterrents.

The bottom line

Cars prone to keyless theft are those with keyless entry and push-button start, across brands and price points, because the vulnerability is in the technology rather than a specific model. The reliable response is not a model list but the keyless precautions - signal-blocking the key, good habits, a visible deterrent and an immobiliser - paired with a tracker as the recovery backstop if a car is taken despite them.

So cars prone to keyless theft are keyless-entry, push-start cars across brands - a technology risk, not a model list - best met with key signal-blocking, good habits, deterrents and an immobiliser, paired with a tracker as the recovery backstop.

Keyless theft is only one method

It also helps to keep keyless theft in proportion: it is one method among several, and a car can be taken in other ways too, so focusing only on the keyless risk can leave other gaps. Protecting a car well means thinking about theft broadly rather than treating keyless entry as the only concern, even on a car that has it.

This is another reason a layered approach makes sense - signal-blocking habits address the keyless route, while a visible deterrent, an immobiliser and a recovery tracker address theft more generally. A car protected only against one method is less well covered than one protected in depth, whatever the specific vulnerability of its key system.

So treat keyless theft as one method among several rather than the only risk - addressing it with key habits while a deterrent, an immobiliser and a tracker cover theft more broadly, since depth of protection matters more than guarding a single route.
