Steering Wheel Lock Malfunction (Here Is What To Do)

steering wheel lock malfunction

Steering wheel lock malfunctions can be a worrying experience for drivers, as they can severely impact the control and safety of a vehicle.

In this comprehensive guide, we will explore the various causes and solutions for steering wheel lock malfunctions, drawing from a range of expert sources.

1. Ignition Lock Activation While Parked

Many modern cars with turn-key ignitions are equipped with an ignition lock feature. This feature prevents the steering wheel from being turned when the key is removed from the ignition, acting as a handy anti-theft measure.

However, if you’re not familiar with this feature, it can create an alarming situation when the steering wheel lock is inadvertently activated.

How to Deactivate the Ignition Lock

To deactivate the ignition lock, insert the key into the ignition and turn it. Be aware that there may be significant tension on the lock cylinder, preventing the key from turning.

To release this tension, gently turn the steering wheel. It should be able to move slightly in at least one direction, which will release the tension on the lock and allow the key to turn and disengage the lock cylinder.

It’s essential to remember that you might accidentally activate the steering lock if you use the steering wheel to help you enter or exit the vehicle.

2. Difficulty Turning the Steering Wheel

If the steering wheel suddenly becomes much more challenging to turn, particularly at low speeds or when stopped, it may not be due to the wheel being locked.

Instead, there could be an issue with the power steering system. Power steering makes steering easier by requiring less force when turning the wheel. A change in the amount of force needed may make it seem as though the wheel won’t turn at all.

Potential Power Steering Issues

There are several potential issues with the power steering system. The power steering pump can sometimes become stuck or jammed if debris finds its way in.

Alternatively, the power steering system could spring a leak, leading to a loss of power steering fluid. Whatever the problem with the power steering, it’s crucial to address it promptly, as a lack of precision and extra exertion can hinder your ability to respond to danger quickly.

3. Steering Wheel Locks Upon Starting the Vehicle

If the steering wheel locks as soon as you turn on your car, the good news is that this problem is often easily remedied.

The steering wheel has a lock that activates if someone moves the wheel when there’s no key in the ignition, making the vehicle more challenging to steal.

However, if you’ve moved the wheel before turning on the car, the lock may still be in place.

Unlocking the Steering Wheel

To unlock the steering wheel, gently try to move the wheel while turning the key. Jiggling the wheel may also work, but the key is to ensure that there’s pressure on the steering wheel while the ignition key is being turned.

4. Steering Wheel Locks While Driving

A steering wheel locking while driving is a terrifying experience, but thankfully, it’s not very common. If it does happen, it’s likely due to a failure in the suspension or steering rack, or column.

In this situation, keep trying to turn the wheel while slowly and safely braking. Make sure to put on your hazard lights and get away from traffic as soon as possible.

5. Locked Steering Wheel Due to Key Issues

If your steering wheel won’t unlock, it could be due to a problem with the key itself. Rounded or chipped teeth on the key will no longer engage the pins in the ignition cylinder to the depth necessary to spin it, resulting in the key failing to turn in the ignition and preventing the wheel from being unlocked.

Solutions for Key-Related Issues

If you have a spare key, try using it to unlock the ignition. If it works, the key you regularly use has likely become worn down and needs to be replaced.

Do not copy a damaged key; instead, get a replacement key cut by a dealership that works with your vehicle’s make and model.

6. Issues with the Ignition Cylinder

The steering wheel lock is secured by the ignition cylinder lock. If the ignition cylinder has seized, spraying a small amount of electrical cleaner into the keyhole may lubricate it enough to turn.

Be careful not to spray too much into the keyhole; a few short squirts should suffice. Once done, insert the key and turn it back and forth gently to work the lubricant in.

If this works, you may need to replace the ignition cylinder soon, as it can get progressively worse. Liquid graphite may also work to lubricate the cylinder.

7. Debris in the Ignition

Debris caught in the ignition can prevent the key from turning, which will, in turn, prevent the steering wheel from unlocking.

Purchase canned air from a local retail or office supply store and insert the straw from the nozzle directly into the keyhole. A few short sprays should be enough to clean out any debris.

Always wear eye protection before spraying canned air into the keyhole to prevent debris from getting into your eyes.

8. Sticking Lock Pins

Sticking lock pins can be lubricated using powdered graphite applied directly inside the keyhole. Graphite comes in small tubes designed to “squirt” the powder with enough force to reach the back of any keyhole. It can be added when needed.

9. Replacing the Ignition Lock Assembly

If the ignition lock assembly needs to be replaced, it can be done at home by most hobby mechanics. Before getting started, order a replacement assembly from your local auto parts store, providing the exact year, make, and model of your vehicle to get the correct replacement part.

Follow the instructions provided in your vehicle’s repair manual to remove the cover over the ignition, release the ignition assembly, and replace it with the new one.

Ensure that the new ignition switch is well-greased and the internal lock pins can move freely before sliding the cylinder into place and reconnecting the switch plug.

10. Warning Signs and Seeking Professional Help

If you notice the steering lock warning light on your dashboard at any time other than when the ignition is in the off position and the lock is engaged, it’s essential to have your car checked out by a qualified technician.

If the warning light doesn’t go out or turns on again later, consult a certified technician to diagnose and address the problem.

In conclusion, steering wheel lock malfunctions can have a variety of causes, from issues with the ignition lock to problems with the power steering system.

Understanding these causes and knowing the appropriate solutions can help you maintain control of your vehicle and ensure your safety on the road.
