What to do if your key wont turn in the ignition?

The issue is usually mechanical or security-related. Start with gentle, non-destructive checks: wiggle the steering wheel, ensure the car is in Park, try a spare key, and avoid forcing the lock. If these steps don’t work, it's safer to call for professional help rather than risking damage.

Ignition problems can stem from a locked steering column, a misaligned gear selector, a worn key, debris inside the lock, or issues with the vehicle’s anti-theft system. The approach typically moves from simple home checks to professional service when necessary, with safety and property protection as top priorities.

Common causes

Steering wheel and gear interlock issues

In many cars, the steering wheel lock can bind the ignition, and the key may not turn even when properly inserted. The interlock between the gear selector and ignition is designed to prevent starting unless the lever is in Park or Neutral.

Before attempting the list below, consider these common culprits and checks.

1. Steering wheel lock engaged or a stiff steering column


2. Gear selector not fully in Park (automatic) or Neutral (manual) or faulty shift interlock


3. Worn or damaged key or worn ignition cylinder


4. Debris, dirt, or corrosion inside the ignition cylinder


5. Immobilizer/anti-theft system not recognizing the key


6. Additional mechanical binding within the steering column or ignition components

If none of these common causes apply, a professional diagnostic can determine if the problem is more serious or electrical.

Safe-at-home steps to try

Practical checks you can perform at home

These steps are safe, practical checks you can perform before calling for help. They aim to free or diagnose a jammed ignition without causing damage.

1. Ensure the gear selector is fully in Park (automatic) or Neutral (manual) and that the parking brake is engaged.


2. Gently wiggle the steering wheel left and right while attempting to turn the key. Do not force the key if it resists beyond a normal amount.


3. Try a spare key if you have one, as a worn or damaged key can fail to engage the tumblers.


4. Inspect the key for damage, bending, or heavy wear; replace if broken or visibly worn.


5. If the cylinder feels dry or stiff, apply a small amount of graphite powder (not oil-based lubricants) to the key and reinsert. Twist gently to distribute the powder.


6. Keep the ignition clean: use compressed air or a lint-free cloth to remove dust or debris from around the keyway; do not spray liquids into the cylinder.

Note: If the key still won't turn after these steps, do not force it further. For many vehicles, proceeding to professional help is the safest option.

When to call a professional

Indicators that you need expert assistance

Certain situations require a locksmith, tow service, or dealership to avoid further damage or safety risks. Consider contacting one if the following apply:

1. The key breaks off in the ignition and cannot be removed.


2. The ignition cylinder is jammed and will not turn with any key.


3. The steering wheel remains locked despite attempts to move it and turn the key.


4. The immobilizer/anti-theft light indicates the key is not recognized or cannot be re-synced after maintenance.

In these cases, a qualified technician can extract and replace a damaged cylinder, reprogram immobilizer keys, and prevent further damage to the ignition or steering system. If the car is immobile, they may arrange towing and safe transport to a service location.

Summary

Key takeaways: Most ignition-fit problems are mechanical (steering lock, gear interlock, worn keys) or related to debris and immobilizer systems. Begin with gentle wheel movement, correct gear selection, and, if available, a spare key. If these steps don’t resolve the issue, avoid forceful twisting and seek professional assistance to prevent damage and ensure safe operation.

How do you fix a key lock that won't turn?

If a key won't turn in a lock, first try wiggling the key while applying gentle turning pressure to help align the internal pins. If that doesn't work, lubricate the lock with a graphite-based spray or powder, working the key back and forth to distribute the lubricant. Check if the door is misaligned, which can put pressure on the lock mechanism. If the problem persists after these steps, you may need to call a locksmith, as the lock or key may be worn or damaged.

Basic troubleshooting

• Wiggle the key: Gently jiggle the key up and down while trying to turn it. This can help misaligned pins and tumblers line up. 
• Check for debris: Look inside the keyhole for any visible dirt or debris and try to dislodge it with a blast of compressed air or a lock lubricant spray. 
• Lubricate the lock: Spray a graphite-based lubricant into the keyhole. Avoid oil-based lubricants, which can attract more dirt. Insert and remove the key a few times to work the lubricant in, then try to turn the key again. 
• Align the door: Ensure the door is not sagging or misaligned, which can cause the bolt to bind. You can test this by trying to lock or unlock the door with the door slightly ajar.

When to seek professional help

• Worn or broken key: If the key appears worn or damaged, or if it breaks off in the lock, a locksmith can replace the key or extract the broken piece. 
• Persistent issues: If the lock still won't turn after trying the steps above, there might be internal damage to the lock cylinder or pins. 
• Unusual or complex locks: Some car ignitions or high-security locks may have specific issues that require professional tools and expertise.

Can I spray WD-40 in an ignition switch?

No, you should not spray regular WD-40 into an ignition switch because it can attract dirt and dust over time, making the problem worse and potentially causing damage. It is best to use a graphite or dry silicone lubricant specifically designed for locks and ignition cylinders.

Why you should avoid WD-40

• Attracts dirt: WD-40 is a solvent and water displacer, but its oily residue can attract dirt and dust, which will mix with the lubricant to form a gritty paste. This can cause the lock mechanism to seize up, making the key difficult to turn. 
• Can cause damage: Its solvent properties can also potentially damage plastic components within the ignition switch, and its tendency to thicken over time is not ideal for lock cylinders. 
• Temporary fix: While it might provide a temporary fix, the long-term effects are negative and can lead to a more serious and costly repair. 

What to use instead

• Graphite lubricant: This is a dry lubricant that will not attract dirt and is ideal for lock cylinders. 
• Dry silicone spray: Similar to graphite, this is a dry, non-stick lubricant specifically made for locks that will not attract dirt and residue. 
• Contact cleaner: If the issue is dirt and grime, an electrical contact cleaner can be used to clean the contacts first, followed by a proper dry lubricant. 
• How to apply: Spray the dry lubricant directly into the key slot and work the key in and out several times to distribute the lubricant evenly.
