The short answer. A key that will not come out of the ignition is usually the car declining to release it rather than a lock that has broken. On an automatic, a shift interlock holds the key until the vehicle is satisfied the selector is fully in park; a lever sitting a hair short of the stop will hold a key all night. The other frequent causes are a switch that has not returned all the way to the lock position and a flat battery on designs whose interlock needs power to let go. All three are free to resolve. The mechanical faults underneath them are not, but they are also rarer.
KeyAtlas is an independent directory of third-party automotive locksmith businesses. It cuts no keys, services no ignitions and dispatches no technicians. This guide sets out the order the trade works through the problem so you can find the free fix first.
The release sequence, in order
Run these in sequence. Each one is free, and the list is ordered by how often it works.
1. Put it properly in park. Press the brake pedal, move the selector firmly into park, then push it gently against the stop. On many vehicles the detent has enough travel that a selector looks parked while the switch that reports park has not closed. Rocking the lever a few millimetres in both directions while trying the key resolves a large share of stuck keys on its own.
2. Return the key fully to lock. Most ignitions release the key only in the final lock position, not in accessory and not in the off position that precedes it. Turn the key fully anticlockwise, feel for the last detent, and try again. It is common to believe the key is at the end of its travel when there is one more click to go.
3. Unload the steering column. If the front wheels are turned against a kerb or the car sits on a slope, the column lock can be under load — the same mechanism that stops a key turning on the way in. Rock the steering wheel gently in both directions while trying the key. That fault has its own guide: key will not turn in the ignition.
4. Check whether the car has power. No dash lights and no response from the ignition, combined with a trapped key, points at the battery. On vehicles whose interlock is an electrically operated solenoid, no power means no release. Jump-starting or charging usually frees the key the moment the circuit wakes up.
5. Nudge, do not pull. Light wiggling while easing the key out is fine. Force is not. A key snapped inside the barrel replaces a free fix with an extraction, and extraction is a specialist job — see broken key in the ignition or door lock.
If all five fail, the cause is mechanical and the next section applies.
What is actually holding the key
Four systems can trap a key, and they fail differently.
The shift interlock. A cable or solenoid linking the selector to the ignition. It exists to stop a vehicle being left out of park with the key removed. Cables stretch, solenoids fail, and the park switch can drift out of adjustment with age. When this is the culprit the key usually turns perfectly and simply will not withdraw — a clean, isolated symptom.
The lock cylinder. Worn wafers, a weak retaining spring or a bent key can leave the cylinder unable to reach the position that releases the key. Suspect this when the release has been getting gradually stickier over months, or when the key also turns roughly. Heavy key rings are a genuine contributor: the constant leverage of a loaded ring accelerates wear on a part designed to carry a key and nothing else.
The ignition switch or actuator behind the cylinder. The electrical half of the assembly, separate from the lock you put the key into. When this fails the vehicle's own sense of which position it is in stops matching reality — dash lights behaving oddly alongside a trapped key is the pattern.
Debris or a damaged key. A bent blade or a burr from a worn key can catch on the way out. If the key has ever been forced, this is the first thing a technician looks for.
What each outcome costs
| Cause | Typical repair | Relative cost | Tell |
|---|---|---|---|
| Selector not fully in park | Seat the selector — nothing to buy | Free | Releases on the first try once parked properly |
| Key not returned to lock | Complete the rotation | Free | A click of travel remains |
| Flat battery on a powered interlock | Jump or charge | Cost of the battery service | No dash lights at all |
| Interlock cable or solenoid | Adjust or replace the component | Low end of a service visit | Key turns fine, only release fails |
| Worn lock cylinder | Rebuild, or replace and re-key to your key | Higher — labour-intensive | Release has been worsening for months |
| Snapped blade | Extraction, then whichever repair above applies | Extraction charged on top | Someone pulled hard |
Two points worth carrying into the phone call. A cylinder replacement should normally be re-keyed to your existing key, so that one key still opens the doors and the boot; skip that and you carry two keys for one car permanently. And when a new key is needed as part of the repair, it should be cut to code from the vehicle's specification rather than copied from the worn key that contributed to the problem — the same reasoning as in car key replacement cost [2].
The security question, while it is stuck
This matters more than most drivers assume. An ignition that has not returned to the lock position frequently means the steering column has not locked either, and the vehicle's own anti-theft protection is part of a regulated design intended to make theft harder [3]. A car standing in a public car park with its key in the barrel and its steering unlocked is a straightforward opportunity.
So while you work the sequence above, treat it as time-limited. If the key will not free and the vehicle is somewhere public, arrange the repair promptly or have the car moved somewhere secure rather than leaving it overnight. This is also the one situation where a mobile technician earns their trip charge outright, since the vehicle genuinely should not be left — the economics of that visit are in mobile car key service cost.
How long the repair takes
If the fault is the interlock or an adjustment, this is usually a short visit — well under an hour once someone is at the car. A cylinder rebuild or replacement is longer, because reaching a column-mounted cylinder can mean removing trim and working carefully around airbag components, and because re-keying the new cylinder to your existing key is a separate operation from fitting it.
Arrival time is usually the bigger number, and it is geography rather than workload. The stages and the realistic ranges are set out in how long does it take a locksmith to make a car key.
What this is not
The key will not go in, or goes in but will not rotate. That is the opposite fault with different causes: key will not turn in the ignition.
The key turns and the engine will not start or dies immediately. The cylinder is doing its job; the problem is electronic. See car starts then shuts off and security light flashing and the car will not start.
A push-button vehicle. There is no key to be stuck. If the car will not detect the fob, start at key fob not working, what to check first.
If the picture is still muddled, is it the key or the ignition is the general triage.
Who to call, and what to tell them
Where the cylinder is involved this is automotive locksmith work — cutting to code, rebuilding cylinders and re-keying replacements are the trade's core skills, described in what an automotive locksmith does. Where the fault is purely the interlock or the park switch, a general mechanic may equally resolve it; the two trades genuinely overlap at this particular fault, and a shop that says so is being straight with you.
Have ready: year, make, model and trim; whether the transmission is automatic or manual; whether the key turns normally; whether the dash lights up; whether the release has been getting worse over time; and whether anyone has pulled hard on the key. That is enough for a shop to tell you over the phone which of the six outcomes in the table you are probably looking at.
Confirm the business name, address and price basis before work starts, as consumer-protection guidance recommends for any dispatched trade [1]. The full checklist is how to verify an automotive locksmith.

Frequently asked questions
Why will my key not come out of the ignition?
On an automatic, the usual reason is that the vehicle does not believe it is in park. A shift interlock physically blocks key release until the selector is fully seated, so a lever resting a fraction short of park will hold the key indefinitely. The next most common causes are the switch not having returned all the way to the lock position, and a flat battery on vehicles whose interlock needs power to disengage.
How do I get a key out that is stuck in the ignition?
Work in this order. Press the brake and move the selector firmly into park, then rock it against the stop. Turn the key fully anticlockwise to the lock position rather than leaving it in accessory. Rock the steering wheel gently in both directions to unload the column lock. Then try the key with light pressure. Do not pull hard — a key snapped off in a barrel is a far more expensive problem than the one you started with.
Can a dead battery cause a key to stick in the ignition?
On many vehicles, yes. The shift interlock on those designs is a solenoid that needs electrical power to release, so a flat battery leaves it holding. It is a distinctive combination: no dash lights, nothing happening when you turn the key, and a key that will not come out. Restoring power usually releases it immediately.
Is a stuck key dangerous to leave in the car?
It is a security problem rather than a safety one. A key sitting in an ignition that has not returned to lock often means the steering is not locked either, and the vehicle is easier to take. If the key cannot be freed, do not leave the vehicle unattended in a public place for long — arrange the repair, or have the vehicle moved somewhere secure.
What does it cost to fix a key that will not release?
As of September 2026, when the cause is the interlock or the selector the fix is often adjustment rather than parts, so it sits at the low end of a service visit. A worn cylinder that has stopped releasing properly costs more, because it means a rebuild or a replacement with re-keying so that one key still works every lock. Extraction of a snapped key is charged separately and on top.
Should I call a locksmith or a mechanic?
If the key turns normally and the problem is only release, either trade may resolve it — the interlock and selector adjustment sit at the boundary. If the cylinder itself is worn, binding or damaged, an automotive locksmith is the specialist, because that work involves cutting to code and re-keying the replacement so your existing key still works the doors.
Can I just leave the key in and keep driving?
People do, and it is the point at which a small repair turns into a large one. A cylinder that will not release is wearing, and the next stage is usually a key that will not turn at all — which strands the vehicle wherever it is parked rather than where you chose. It also leaves the car standing unlocked with its key in it every time you walk away.
