Are Steering Wheel Locks Worth Buying to Stop Car Theft?

A steering wheel lock is a highly visible deterrent that makes your car much more trouble to steal. An opportunist thief looking for a quick getaway is more likely to move on to an easier target when they see a heavy bar clamped across your dashboard. It does not make your car completely theft proof, because a determined criminal with heavy tools may eventually defeat any lock. However, it is a simple way to make your car a harder target, whether it is parked on the drive or in a public car park.

A steering wheel lock is a large, visible lock that clamps around the steering wheel so it cannot be turned. With the wheel locked, the car is much harder to drive away.

A thief looking through your car window can see the lock straight away and may decide the car is more trouble than it is worth. Pedal locks are a similar visible type, and they lock the brake or clutch pedal instead of the wheel.

Why a visible lock puts thieves off

Many thieves want a quick, quiet getaway, and a lock that is easy to see can put them off before they start.

Lichfield District Council provides clear stopping car theft advice that explains this psychology. Their guidance states that most car thieves want a quick getaway. The council says that if a thief sees a steering wheel or pedal lock, they are more likely to give up and look for a car without one.

Lichfield District Council and Secured by Design both treat the lock as a deterrent, which means its main job is to make a thief look elsewhere. It does not stop a determined thief.

What the police backed advice says

Secured by Design is the police security initiative. Its advice on motor vehicle crime for cars and vans calls a steering wheel lock an effective visual deterrent.

Consumer groups agree that you do not need the most expensive model on the market to get some benefit. A 2019 report by Which? advised drivers to invest in a steering wheel lock because even cheap ones will act as a deterrent. However, the same report noted that a lock accredited by Secured by Design will be much harder for thieves to break. In that 2019 report, Which? put the price of those police accredited locks at around £120.

A more recent 2026 update by the motoring magazine What Car? reached the same conclusion. They stated that a steering wheel lock can be an effective and visible theft deterrent. They noted that fitting one will help dissuade opportunist thieves from targeting your vehicle. These guides all treat a visible lock as a worthwhile deterrent, and Which? says an accredited one is much harder to break.

What to look for when buying one

Many steering locks make bold claims on the packaging. You should ignore marketing hype and look for independent testing instead. What Car? noted in its 2026 article that security ratings come from an industry standard testing house, which is why its own test looked at day to day usability.

When choosing a lock you should look for these specific features.

• Secured by Design accreditation, which Which? says makes a lock much harder for thieves to break.
• Clear product measurements that prove the clamp will fit over your specific steering wheel.
• A design that suits your steering wheel, including the centre of the wheel.
• A reasonable weight and size that you can comfortably lift and fit from the driver seat.

A lock accredited by Secured by Design will be much harder for thieves to break, according to Which? Check the packaging or the manufacturer website for the Secured by Design accreditation rather than relying on the maker's own claims.

Usability is just as important as the metal the lock is made from. What Car? concentrated their 2026 tests on day to day usability across three different vehicles. If a lock is too heavy, awkward to position, or difficult to lock in the dark, you will eventually stop using it. Look for a model that you can fit and remove comfortably every single day.

Where a steering lock falls short

No security product offers a total guarantee against theft. A steering lock is a visible deterrent, not a barrier that cannot be beaten, and a determined thief with tools may defeat any lock.

A physical lock also does nothing to stop thieves breaking a window to steal items left on the seats. It only stops them steering the car away. You still need to remove your bags, coats, tools and electronics when you park. Leaving valuables on display will invite a break in, even if the car itself cannot be moved.

You must also consider the practical limits of storing a heavy metal bar inside the cabin while you are driving. You will need secure space in the boot or firmly wedged behind a seat to keep the lock safe. In a sudden stop or a crash, a loose metal steering lock flying through the cabin can be very dangerous to the driver and passengers.

Steering locks on keyless cars

On a keyless car, a relay attack uses a device to extend the signal from your key, so the car thinks the key is closer than it really is and unlocks and starts.

A steering lock does nothing to block the signal, so it does not stop a keyless car being unlocked or started. A locked wheel can still make the car harder to drive away.

To protect a keyless car properly you must tackle both the electronic signal and the physical steering wheel. What Car? recommends pairing a physical steering wheel lock with a signal blocking pouch for keyless cars. These signal blocking bags are often called Faraday pouches.

What Car? tested several pouches, with prices as tested ranging from £3.00 to £29.99 (article updated May 2026). Their test found that every single pouch successfully blocked the key of a keyless 2016 car. A pouch that fails is no use, so test it, and remember that no measure guarantees against theft.

Other cheap steps worth taking

Secured by Design advises taking several other straightforward steps to protect your vehicle alongside a steering lock. You should store your electronic key in a security pouch that blocks signals from keyless entry fobs. Secured by Design also says to test the pouch every few months to make sure it is working.

They also advise always locking your vehicle and closing all windows when it is left unattended. This sounds obvious, but you must do this whether the car is parked on your own drive, at a petrol station forecourt, or in a public car park.

You can also improve your security by changing where you choose to leave the car. When you are away from home, Secured by Design suggests parking in a Safer Parking approved car park.

Consider these other simple security upgrades to protect your vehicle.

• Fitting a lock to the vehicle onboard diagnostic port to prevent the vehicle being reprogrammed by thieves.
• Installing a tracking device, which can help recover a vehicle if it is stolen.
• Keeping your car keys, including spares, well away from doors and windows.
• Checking that the car has actually locked by pulling the door handle before you walk away.

Using it properly every time

A steering wheel lock only works if it is actually fitted to the wheel every single time you park. Many drivers buy a lock, use it for a while and then get tired of the routine. Leaving it in the boot because you are only popping into a shop defeats the point.

You need to practice fitting and removing the lock until it becomes a fast, natural habit. Fit it so that it can be seen clearly through the glass by anyone walking past the car.

Keep the small key for the steering lock on a separate ring from your main car key. If you leave them together and lose the bunch, you lose both. An auto locksmith can help with lost or stuck steering lock keys. If you have lost the main fob too, you will need to arrange replacement keys before you can drive, which is a stressful process if you lose your only car key with no spare.

Common questions

Do steering wheel locks damage the steering wheel?

Some heavy metal locks can leave dents or scratches on soft leather steering wheels if they are clamped on too tightly or fitted in a rush. Look for models with a protective rubber or foam coating on the metal hooks.

Can a steering lock be beaten?

Yes, a determined thief with tools may defeat any lock, which is why a steering lock is a deterrent and not a guarantee. Which? says a lock accredited by Secured by Design will be much harder for thieves to break than a cheap one.

Are pedal locks better than steering locks?

Pedal locks are a similar visible type of lock that attach to the brake or clutch pedal. Choose the one that suits your car and that you will fit every time.

Will a steering lock lower my car insurance?

Insurers differ, so check your own policy wording or ask your insurer whether a steering lock makes any difference to your cover or premium.

Can a locksmith help with a stuck steering lock?

An auto locksmith can help with lost or stuck steering lock keys. Ask for a total price before they start.

Next steps to secure your car

You should make sure you pick the right model and use it consistently alongside other good security habits. Follow this checklist to get your vehicle security in order before you park on the street again.

• Check your steering wheel dimensions to ensure the lock will fit over the rim and the central airbag housing.
• Look for a lock that holds a Secured by Design accreditation or an independent industry standard security rating.
• Buy a signal blocking Faraday pouch if you drive a keyless entry car to protect against relay theft.
• Test your new signal blocking pouch by standing next to the locked car with the key inside the pouch to ensure the doors stay locked.
• Practice fitting the steering lock until you can do it quickly and comfortably in the dark.
• Make sure you always lock the doors and close all the windows when leaving the car unattended, even for a moment.
