Quick answer:
- Wiggle the steering wheel while turning the key — this solves most cases.
- Never force it. A snapped key inside the lock is a far worse problem.
- A worn key or a worn lock cylinder is the next most common cause.
Try This First
The overwhelming majority of stuck keys are a steering lock binding under load. When you park, if the front wheels are turned or resting against a kerb, the steering lock engages under tension — and that pressure prevents the key cylinder from rotating.
- Grip the steering wheel and apply gentle pressure left and right. You may feel it move very slightly.
- While rocking the wheel, turn the key gently. Do not force either.
- Try both directions — whichever way relieves the tension is the one that works.
This is common on hilly streets, where wheels are habitually turned into the kerb. Roswell, Buckhead, and much of the north metro produce this constantly.
If the Wheel Trick Does Not Work
Work through these in order:
- Check the shifter is fully in Park. Almost in Park is not in Park. Move it firmly, and try Neutral.
- Try the spare key. If the spare works, your everyday key is worn — a very common and cheap fix.
- Inspect the key. Visible wear, bending, or a cracked plastic head all cause this.
- Check for obstruction in the keyway — debris or a bent key can prevent the pins seating.
- Consider temperature. Extreme cold can thicken lubricant in the cylinder.
- Note whether it is worsening. A lock that has been getting stiffer for weeks is a wearing cylinder.
Do Not Force It
This is the one genuinely important warning. A key snapped off inside a lock cylinder turns a minor annoyance into an expensive job requiring extraction and often full cylinder replacement.
The same applies to pliers, penetrating oils, and lubricant sprays. Most general-purpose lubricants attract dirt into the cylinder and make things worse over time; if lubrication is genuinely needed, a lock cylinder wants a dry graphite product, not an oil.
If gentle wheel-rocking and the spare key both fail, stop and get it looked at. The cost of a stuck-key diagnosis is a small fraction of an extraction plus a new cylinder.
What It Usually Turns Out to Be
In rough order of frequency: a steering lock under tension — solved on the spot. A worn key, solved by cutting a fresh one from the code. A worn lock cylinder, where the internal wafers no longer align reliably; this typically worsens gradually and needs replacing.
Less commonly, a fault in the shifter interlock on cars that require Park before the key will turn, or an ignition switch problem behind the cylinder.
This is straightforward mobile work in the great majority of cases — there is no reason to tow a car whose only problem is a lock cylinder.

Frequently Asked Questions
Why does wiggling the steering wheel work?
Because the steering lock is usually the culprit. Parking with the wheels turned leaves the lock engaged under tension, which physically prevents the cylinder rotating. Rocking the wheel relieves that pressure.
Should I spray lubricant into the ignition?
Avoid general-purpose oils — they attract dirt and make things worse over time. If lubrication is needed, a dry graphite product is the right choice, but if the lock is worn, lubricant only postpones the repair.
My spare key works but my main one does not. Why?
Your everyday key is worn. Keys wear gradually with use, and eventually the worn pattern stops aligning the lock wafers. Cutting a new key from the code is usually a cheap fix.
Can a stuck key be fixed at my location?
Usually yes. Diagnosis and most lock cylinder work is straightforward on-site — there is rarely any reason to move the car.
What if the key snaps off in the lock?
Stop and call. Do not attempt to extract it with tools, as that commonly pushes the fragment deeper and damages the cylinder further.
