If your key will not turn in the ignition, the most common cause is a locked steering wheel or damaged ignition. Wiggle the wheel firmly left and right while you gently turn the key at the same time. If that does not free the ignition, rock the shifter in and out of park, try your spare key to see if your key is worn, and on a push-to-start car check the key fob battery. If the ignition still does not turn, it means it has worn or damaged wafers. A locksmith can fix both.
These fixes are listed from the simplest and safest to the ones that can damage the ignition, so try them in order. Most cars are turning again by step two, and even a failing cylinder can usually be coaxed to turn just enough to reach a shop.
Free the steering wheel first
A steering wheel locks after the key is removed, as an anti-theft feature, and it also locks if the wheels were turned while the engine was off. A locked wheel binds the ignition so the key will not rotate. Turn the wheel hard in the direction it will move while applying light, steady pressure on the key. The instant the lock releases, the key turns. This single step solves most stuck ignitions.
To free the ignition, work through this list, in order
If the wheel already turns freely, the steering lock is not the problem, so go straight to the list below.
- Rock the gear shifter firmly in and out of park, then try the key. An automatic that is not fully seated in park stops the ignition from turning by design.
- On a push-to-start vehicle, a weak key fob can block the start sequence even though the dash lights up. To start it, hold the brake and press the START button with the fob itself touching the button. The car reads the chip inside the fob at close range. Replace the fob battery afterward.
- Try your spare key. If the spare turns the ignition, your main key is too worn out. Get a copy made of the spare key.
- Spray a Teflon (PTFE) lubricant such as Tri-Flow into the ignition, then insert and try to turn. Skip graphite, which builds up and can foul the ignition switch’s electrical contacts, and skip oily sprays like WD-40 that gum up the cylinder.
- Insert the key fully and jiggle it gently while turning. Do not force it, forcing it to turn can snaps wafers and keys.
- With the key inserted, tap it lightly with the heel of your hand or back of a screwdriver while turning, which can reseat stuck wafers.
Is it the key or the ignition cylinder?
If the spare works, the issue is a worn key. Keys cut from a copy of a copy drift out of spec until they no longer line up the wafers, and keys wear out over time. A locksmith can cut a fresh key using your VIN or a lock’s code. This gives you a factory original key, and the problem disappears.
If you’ve tried more than one key and the ignition still doesn’t turn, the wafers inside the ignition cylinder are damaged or stuck. But often, you can often get it to turn just once more so you can drive it to a shop, which saves a tow.
When replacing a failed ignition cylinder – take it to a locksmith first
When the cylinder is shot, it can be rebuilt or replaced. You can also buy a new ignition cylinder online (eBay has good prices on ignitions), but new ignitions ship with their own key. To use your existing keys, and not have to pay to get keys programmed to your car, take the new ignition into an automotive locksmith with your old (existing) keys. The locksmith will swap the wafers on site so your current keys will work it. No need for key programming, no need to have a different ignition key for the door. A locksmith rebuild or rekey usually runs about $100 to $300, and a full cylinder or switch replacement about $200 to $400 depending on the vehicle, well under the cost of a tow plus a dealer visit.
Keep it from happening again
Stop using a worn or bent key the moment a fresh-cut spare turns more smoothly, since a worn key wears the cylinder too. Keep the keyway clean with a dry lubricant once or twice a year, and do not hang heavy keychains off the ignition key, the weight wears the cylinder over time.
When to call an auto locksmith
If the key still will not turn, or it turns roughly every time, have it looked at before you get stranded.
