Nine great car security tips

Car crime – increasingly keyless theft – blights many lives, piling more pressure on our insurance costs.

Having a good level of car security is key for any vehicle owner.

According to the Office of National Statistics (ONS), there were 56,000 vehicle thefts between May 2020 and March 2021.

In the same period, there there were 474,000 thefts from vehicles. Which means belonging were stolen from inside the vehicle itself.

Overall, there were 697,000 counts of vehicle-related theft between May 2020 and March 2021. 

Many car thieves are part of a bigger industry. Some high-value vehicles can be driven to a secure location and then left for several days to be checked thoroughly for tracking devices.

Once ‘cleared’ and the car re-programmed, they can be then sold on. 

So, while car makers get better at making our vehicles more secure, criminals get smarter too.

Car security isn’t always about car keys anymore, there are different types of vehicle theft that use computer hacking, vehicle cloning and organised re-selling, often to order.  

To help protect your vehicle against theft, we’ve assembled the best car security ideas – including those for electric vehicles – that not only protect your wheels but also your car insurance costs.

Prevent keyless theft and buy a Faraday pouch

Keyless entry and start is a convenient feature now on many cars.

While often helpful, keyless entry has one gaping drawback – it can make it easy for car thieves to make off with your car. 

Often working in pairs, car criminals do this by hijacking a car key’s radio signal, sending it to a nearby transmitter handled by an accomplice.

This acts as the ‘key’, letting them open your car up, start the engine drive it away, possibly to be stripped for spare parts.

This method is known as keyless entry car theft.

Luckily a Faraday pouch could help protect you from keyless entry car theft. Most of these have signal-blocking stitching that helps to block out any radio interference.

A small holdall, you simply pop your key fob inside.

Invest in a steering wheel lock 

A tough, loudly-coloured metal lock clamped across your steering wheel is a strong visual deterrent for many car thieves – though not for the most determined. 

While some wheel locks do look a bit on the heavy-handed side, most owners feel their highly visible presence is worth it for the peace of mind. 

If you buy one, make sure it doesn’t lean too heavily on a steering wheel mounted horn or nearby indicator stalk.

Check too that it doesn’t scratch the steering wheel or get in the way of automatic gearbox paddle shifters if you have them fitted. 

Some wheel locks will have a storage bag, while others won’t – again, check. Have a think too about where you’ll store it when driving.

Some vehicles will have space under the passenger seat, but not all. Will you keep it in the boot – and how can you keep it from sliding around?    

Some wheel locks are on the expensive side – think north of £60. But their chunky, robust second line of defence presence is hard to ignore, and in a very good way, we think.

Hang onto your electric vehicle (EV) charging cables

If you run an EV do watch the security of your electric charging cables. Any cables left outside your house, for example, may be vulnerable to theft.

Electric vehicle cable theft is on the rise as the kit is increasingly desired by scrap metal thieves. And, massively increasing electric vehicle sales means it’s a trend. 

Some electric car charging points aren’t easily stolen. But some charging stations rely on EV drivers to use their own cables – and it’s easy to leave these unattended. 

Typically a standard Type 2 BP Chargemaster cable retails for £149 and is widely used across many marques, including Audis, BMWs, Peugeots and VWs.

One get-around here is to consider fitting a dash cam. While it won’t stop the most determined thief, it may at least give them pause.

But do make sure the dash cam has a ‘parking mode’. Some only run when your car is on the move.

If you have a garage, try and keep all your charging kit inside it. It’s best not to over-advertise this increasingly targeted (and not cheap) equipment.

At the start of 2021 there were more than 500,000 electric and hybrid vehicles on UK roads. More than 175,000 electric vehicles alone were registered in the UK last year (2020).

Consider a car tracker

A GPS tracker could be an inexpensive way of pinpointing exactly where your car is. 

Many of us already use GPS satellite technology when using our phones – Google Maps, for example. But you can fit GPS car trackers discreetly to a vehicle, often with a simple adhesive patch. 

Some trackers rely on their own long-life battery while others can be wired up to your car’s on-board diagnostics (OBD) port.

Almost all cars made after 1996 will have an OBD, and you can set them up using your own SIM card.

Have a think too about what you want to use a tracker for. Will you want to use it to track other items, like a bag or bike? 

In other words, there’s plenty of flexibility and choice. Some start from as little as £50, or even less.

A VHF system is also an option – albeit more expensive.

The VHF advantage is that it can track your vehicle down even if it’s been hidden underground, or in a hard-to-find, isolated shipping container. 

There’s also another hard-to-argue-with advantage – a Thatcham-approved VHF tracker could also lower your insurance costs.

Payment for car trackers can vary depending on the manufacturer. You might be able to buy the device with a one off payment, for others you might have to pay a monthly fee via a subscription service.

Fit a car immobiliser

Most cars on the road have immobilisers fitted to them. Immobilisers were required by law since 8 October 1998.

But if your car is older, possibly a classic car, then consider having one professionally fitted.

Before immobilisers became commonly fitted some cars could be ‘hot-wired’ to start without a key.

An immobiliser’s job is to stop an engine being run unless a key – the right one! – is used. 

A car engine will only start if a code inside the key’s transponder chip matches the code planted in the immobiliser, which is usually factory-fitted.

While an immobiliser won’t stop your car being pinched, it certainly slows down a car criminal’s progress.

And the more secure your vehicle is, the lower your insurance premium could be. So they’re good news. 

If you’re having an immobiliser fitted by an aftermarket installer, make sure the device is Thatcham-approved.  

Park in a secure or well lit location

Choosing where to park could have a dramatic impact on how easy or difficult your vehicle is to steal.

Car thieves don’t like well-lit public roads as they’re easily seen. So, side roads or dimly-lit alleys aren’t sensible. 

That’s common sense, of course. But areas of high crime can be easily avoided, even if you don’t know an area well.

A number of websites, like ParkMark, identify well-maintained and run public car parks.

Smartphone parking apps also make secure parking easier to find. Most have easy-to-use interfaces with on and off-street parking options, plus live availability too, in some cases.

Some even allow you to track down private rented driveways as an alternative. 

A number of supermarkets – Morrisons and Tesco are good examples – now rent out parking spaces to non-customers.

In other words, there’s plenty of tools and solutions to help you keep your vehicle secure and your no-claims bonus intact.

But wherever you park, do make sure you park close to other people’s cars. If your car is a bit isolated, it’s easier to be preyed on.

CCTV cameras add another layer of security, of course. 

Buy a car with better security as standard

Thatcham Research, the vehicle and technology research organisation funded by insurers, suggests consumers look at its own car security ratings when choosing their next car.

While premium models often have better security than cheaper cars, it’s not a 100% given. And some ‘premium’ vehicles, by their very desirability, are more vulnerable to being nicked.

Thatcham Research recommends asking a dealer if a keyless fob can be turned off overnight – or if it has an automatic ‘sleep’ function.

Some other questions it recommends asking:

  • Are there any software updates?

  • Is a motion sensor-enabled fob available?

The good news is that some car makers are now switching to better wireless technology such as Ultra Wide Band (UWB) and Bluetooth Low Energy (BLE).

These are thought to be more tamper-proof. 

Keep your paperwork at home 

Never keep your car paperwork inside the car. Always store the logbook and your car service records safe at home.

The most important document is the logbook, or V5C, which is your car’s registration document. 

Although things like VED road tax and driving licences are now digitised, the British logbook, a paper-based hanger-on, has held out.
If your car is stolen with the V5C inside it, you must tell the police and your insurer immediately. You’ll also get a crime number. 

And if you’re buying a car, do make sure the logbook, or V5C, has a ‘DVLA’ watermark and that its serial number isn’t:

  • Between BG8229501 and BG9999030

  • Between BI2305501 and BI2800000.

 If it is, the V5C might be stolen.


Watch out for catalytic converter theft

A catalytic converter is part of a vehicle exhaust and filters out harmful engine emissions. The Association of British Insurers (ABI) warns it’s a growing problem. 

“They have become targets for thieves because of the high value of the metals they contain, rhodium and palladium,” the ABI warns. 

“Rhodium currently sells for just over £10,000 an ounce; palladium for just over £2,000 an ounce.

"Thieves crawl under vehicles, sometimes sawing off the converters so causing more damage. The repair bill can typically range from £2,000 to £3,000.”


How can I protect my car from being stolen?

Here are our top tips to help protect your car from being stolen at a glance:

  • Lock your vehicle – it sounds obvious but double checking that your car is locked could save you time and money. Also, your car insurance policy may not pay out if your car was left unlocked when it was stolen.
  • Invest in multiple layers of security – having a steering wheel lock or handbrake lock will help to secure your car and act as a visual deterrent for thieves.
  • If you have keyless entry software, invest in a Faraday pouch to help protect your car against keyless hackers.
  • Park somewhere secure. If you don't have secure parking, aim for a well lit street.
