Start here: stay calm and do not force it
When a key refuses to come out, the instinct is to yank it. That is the one thing to avoid. A key is a small piece of metal turning inside a precision mechanism, and force can snap the blade inside the ignition, bend the key, or crack parts of the cylinder. A broken key in the ignition is a much bigger problem than a stuck one, and our page on broken key in the ignition explains how much more involved that repair is.
Take a breath and make sure the car is safe. If the car is running, in gear, or on a slope, handle that first. Put your foot on the brake, make sure the vehicle is not going to roll, and apply the parking brake. If you are in a roadway or an unsafe place, turn on the hazard lights and move to safety if you can do so without driving erratically.
Then think about what the car expects. Modern ignition systems include several safety interlocks, which are small mechanisms that stop the key being removed unless certain conditions are met. Most of the time a key is stuck because one of those conditions has not been met, not because anything is broken. Meeting the condition releases the key.
Work through the checks in the next sections one at a time, using gentle pressure only. If a check does not help, stop. A calm call to a professional costs less than a repaired ignition. And if the car is dangerous to leave, such as in a traffic lane, put safety first and call roadside assistance or emergency services as appropriate.
Cause one: the shifter is not fully in park
In an automatic car, the ignition is linked to the gear selector. The key can only be removed when the shifter is firmly in park. If the lever is sitting between positions, even slightly, the interlock holds the key in place. This is the most common reason for a stuck key, and it often happens after someone has parked in a hurry or on a slope.
To check, press the brake pedal, move the shifter out of park and then back into park fully, making sure it clicks into place. On a sloped surface, the car may be resting its weight on the parking pawl inside the transmission, which can make the shifter stiff. Apply the parking brake, then try again.
Check that the shifter is genuinely in the right position by looking at the gear display on the dash. If the display shows park and the key still will not release, the shift lock or the sensor that detects the gear position may be at fault. Some cars have a small shift lock release near the shifter, described in the manual, which is meant for situations where the car loses power. Use it only as the manual describes.
Manual cars have a similar logic. Some require the clutch to be pressed or the gearbox to be in a particular gear before the key will turn to the off position and release. Check your manual, since every make is a little different.
Cause two: the steering lock is under tension
When you turn off the car and open the door, many cars engage a steering lock, a pin that locks the steering column so the wheel cannot turn. If you have turned the wheel while the key is out or while turning the car off, the pin can press hard against a notch in the column. That pressure can bind the ignition cylinder so the key will not turn back or come out.
The classic sign is a steering wheel that is pulled to one side, and a key that will not turn at all or turns only a small distance. Gently wiggle the steering wheel left and right while turning the key with light pressure. The wiggle relieves the pressure on the pin and lets the cylinder move. Do not use force on either the wheel or the key. Small, gentle movements are enough.
If the steering wheel is stuck against the lock and does not move, try moving it in the direction it is already turned, a little at a time, while turning the key lightly. If you have no movement in either direction, stop. There is a risk of damaging the lock or the key by pushing harder.
Some owners find this happens more often when parking with the wheels turned against a curb, because the weight of the car pushes on the steering mechanism. Straightening the wheels before turning the car off often prevents it. Our page on steering wheel lock release describes what a technician does when the wiggle does not help.
Cause three: worn wafers or a worn key
Most mechanical car ignition cylinders use wafers, small flat plates that must be lifted to exactly the right height by the cuts on the key. After years of use, the wafers wear, the key wears, and the two no longer match precisely. The key may then turn but not release, or catch in the middle of the movement.
Signs of wear include a key that has become hard to insert or withdraw, a key that works only when jiggled, an ignition that sometimes fails to start the car, and keys with rounded edges and shallow cuts. A key copied from another worn copy is especially likely to be inaccurate. If your spare key works smoothly, then the old key is probably the problem. If both keys stick, the cylinder is more likely worn.
Try the spare key first. If it is in your pocket or a family member can bring it, it may release the stuck one. If the spare turns smoothly and the original does not, stop using the original. A technician can cut a new key from the car's data or from the lock, and that often solves the problem without touching the ignition.
Do not try to fix a worn lock by pouring oil in. Heavy lubricants gather dirt, gum up the wafers and can make things worse. If you must lubricate, use a small amount of a dry graphite or a product made for locks, applied sparingly. Better still, leave it and ask a professional. Our page on worn car key symptoms explains how to spot a key that is on its way out.
Cause four: a bent, damaged or wrong key
A key that has been bent, even slightly, may enter the cylinder but fail to align the wafers or pins correctly. Keys bend when they are used as levers, when a heavy keychain hangs from them, or when they are dropped and stepped on. The bend may be hard to see, so hold the key against a flat surface or another straight key and look for a curve.
A heavy keychain is a known culprit. A bunch of keys, a fob and trinkets hanging from the ignition key puts constant sideways weight on the cylinder. Over months, that weight wears the cylinder and the key. If your key is stuck and your keychain is heavy, support the weight of the keychain with one hand while you try to turn and remove the key with the other.
Sometimes the wrong key is the problem. A key for another vehicle, or an incorrectly cut duplicate, may fit partly and stick. This is common after a duplicate is cut at a kiosk using the wrong blank. If the key was recently copied, and trouble began soon afterward, the copy may be at fault. Try the original.
For a bent key, do not try to straighten it while it is in the ignition. If it is bent, a technician can usually remove it safely, and cut a new one from the car's information. Straightening a key with pliers can weaken it and make it snap, leaving a piece in the cylinder.
Cause five: electronic and battery related issues
Modern vehicles also use electronic interlocks. If the car's battery is flat, or the shift lock solenoid has lost power, the shifter may not release from park and the key may not come out. The solenoid is a small electromagnet that holds the key until the brake is pressed and the car is in the right state. Without power, it stays locked.
Check whether the car's lights, dashboard and doors behave normally. If the dashboard is dead or dim, or the car clicks without starting, the battery may be flat. A jump start from a trusted source, done carefully and according to the manual, may restore power and release the key. If you are not comfortable, ask roadside assistance.
Some cars with push-button start use a key fob that has to be recognized by the car, and a mechanical emergency key hidden inside the fob. If your car has a slot where the fob is inserted and it is stuck, the issue may be a damaged slot or a fob that has swelled with a failing battery. Do not use force. Look in the manual for how to release the fob, since there is often a procedure.
A transponder key also relies on a chip. If the chip is damaged, the car may refuse to start or may throw an immobilizer warning, but that does not normally cause the key to stick. If you see an immobilizer warning light alongside a stuck key, mention it to the technician. Our page on immobilizer light flashing explains what that means.
Safe steps to try, in order
Work through these steps gently and stop if anything feels forced. First, make sure the car is secure: parking brake on, foot on the brake, engine off. Second, push the shifter firmly into park, and move it out and back again. For a manual, make sure it is in the gear or position the manual specifies.
Third, wiggle the steering wheel gently from side to side while applying light turning pressure to the key. Fourth, if your keychain is heavy, hold its weight up and try again. Fifth, try the key in a slightly different position, withdrawing it a hair and turning gently, since sometimes the wafers settle better that way.
Sixth, try the spare key, if you have one, to see whether it turns the cylinder smoothly. If the spare works, the original key is the problem. If the spare sticks too, the cylinder or the shift lock is more likely to blame.
Seventh, check the battery and the car's electrical state. A flat battery is a common cause that is easy to miss. If you can safely jump start the car, you may release the key. Do not spend a long time on any step, and do not use tools, pliers, hammers or sprays. If none of these steps work within a few minutes, stop and call for help.
When to call a professional and what to say
Call a professional if the key still will not come out after the safe steps, if the key is bent or damaged, if the steering wheel is locked hard, if the dashboard behaves strangely, or if you have already felt the key move or crack. Early help prevents small problems turning into a broken key or a damaged ignition.
When you call, describe what you did and what you saw. Say whether the shifter is in park, whether the key is stuck on or in the off position, whether the steering wheel is locked and whether the key feels bent. Give the make, model and year of the car, and say whether you have a spare. This helps plan the right tools and parts.
Quotes are given by phone only. For a stuck key, a straightforward job can often be quoted from your description. If the ignition cylinder needs replacing, or the problem is more complicated, an on-site visit may be needed first. A service call charge applies for the visit and is explained on the phone before anyone is dispatched.
Expect to be asked for proof that you own the car before any key or ignition work is done. Our page on ignition cylinder replacement explains what happens if the cylinder itself is worn out. When you are ready, call and describe what the key is doing, and the technician will plan the visit.
Questions people ask
Why will my key not come out of the ignition?
The most common reasons are a shifter that is not fully in park, tension on the steering lock, a worn key or cylinder, a bent key, or a flat battery that stops an electronic interlock from releasing. Work through gentle checks and avoid force. If they do not help, call a professional.
Is it safe to pull hard on the key?
No. Force can snap the key inside the ignition or damage the cylinder, turning a small problem into a larger repair. Use gentle pressure only. If the key will not release after a few careful checks, stop and call for help.
What does wiggling the steering wheel do?
When the steering lock pin is pressed against its notch, it can bind the ignition so the key will not turn. A gentle left and right movement of the wheel relieves that pressure and often lets the key turn and come out. Use light movements, and never use force on the wheel or key.
Could a heavy keychain be causing the problem?
Yes. A heavy keychain puts sideways weight on the ignition cylinder and wears both key and cylinder over time. If your key is stuck, hold the weight of the keychain with one hand while turning with the other. Consider a lighter keychain afterward to protect the ignition.
Should I spray oil into the ignition?
It is best not to. Heavy oils attract dirt, gum up the wafers and can make the problem worse. If a lubricant is appropriate, a small amount of a dry lock lubricant is a safer choice, but it is usually better to leave the job to a technician.
How do I get a price for a stuck key?
Quotes are given by phone only. Describe the car and what the key is doing. A straightforward job can often be quoted before dispatch. If the ignition needs replacing or the case is complicated, an on-site visit may be needed first, with a service call charge explained on the phone before anyone is dispatched.
