A car steering lock is a key-operated mechanism or add-on device that prevents the steering wheel from turning and deters vehicle theft.
What Is a Car Steering Lock?
A car steering lock is a security mechanism that stops the steering wheel from turning when the ignition key is removed. It is also called a steering column lock or steering wheel lock. 2 lock types exist: the built-in column lock and the add-on wheel lock device. Examples of add-on devices include The Club and Disklok.
How Does a Built-In Steering Column Lock Work?
According to US patent filings, a built-in steering column lock uses a spring-loaded lock bolt that slides into a notch or groove in the steering column when the key is removed. Turning the key retracts the bolt and frees the column. Turning force from the front wheels binds the bolt in many cases, so the driver turns the wheel to release it before the key turns.
Electronic systems replace the mechanical link to the ignition cylinder with a controller and actuators. NHTSA reviewed a keyless entry system that unlocks the column after the key code is transmitted and the door opens, and locks it when the key is removed.
What Does FMVSS 114 Require for Steering Locks?
FMVSS 114 requires each vehicle to have a key-locking system that prevents engine activation and either steering or forward self-mobility when the key is removed. FMVSS means Federal Motor Vehicle Safety Standard, and No. 114 covers theft protection in the United States. NHTSA states that most manufacturers comply with a steering lock.

What Are the 3 Styles of Steering Wheel Lock Devices?
The 3 styles of steering wheel lock devices are bar-style, enclosed, and pedal-to-wheel locks.
- Bar-style lock: grips the wheel rim with hooks on a rod.
- Enclosed wheel lock: encases the wheel in a metal shell.
- Pedal-to-wheel lock: links the wheel to the brake or clutch pedal with an adjustable steel bar.
Bar-style designs include T-bar, single bar, and double bar models.
Do Steering Wheel Locks Prevent Car Theft?
Steering wheel locks deter theft but do not stop every attempt, because a thief cuts through the wheel rim to remove a bar-style lock. A University of Washington security blog describes The Club as an effective deterrent and lists rim cutting and removal time as vulnerabilities. Mental Floss reports that police officers often described The Club as only a visual deterrent. The maker states that The Club is meant to deter, so a thief who sees it seeks a less challenging target.
Does a Steering Lock Replace an Immobilizer?
No. A steering lock blocks steering, and an immobilizer prevents the engine from starting unless the matching coded key fob is detected. The table shows HLDI and IIHS data on immobilizers and theft claims for Hyundai and Kia vehicles.
| Measure | Result |
|---|---|
| Hyundai and Kia vehicle series with standard immobilizers by 2015 | 26% |
| All other manufacturers’ vehicle series with standard immobilizers by 2015 | 96% |
| Theft claim frequency, 2015 to 2019 Hyundai and Kia vehicles compared with other makes | Nearly 2 times as common |
| Theft claim frequency after the software upgrade compared with no upgrade | 53% lower |
| Whole vehicle theft frequency after the software upgrade compared with no upgrade | 64% lower |
HLDI states that missing immobilizers made many Hyundai and Kia vehicles easier targets for thieves.
How Do You Unlock a Locked Steering Wheel?
Hold pressure on the key in the turning direction while wiggling the steering wheel left and right. The Drive lists these steps:
- Insert the key into the ignition.
- Hold pressure on the key in the turning direction.
- Wiggle the steering wheel left and right.
- Turn the key to start the engine once the lock releases.
NAPA states that a locksmith produces a replacement key from the vehicle serial number, if a worn key fails to move the lock tumblers.

Why Does a Steering Wheel Lock Up?
A steering wheel locks up when the lock bolt engages after key removal and turning force binds it in the notch. Causes include a worn key and bolt binding. Binding creates larger problems in electronic locks that lack a mechanical link to the ignition cylinder.
