Can a locksmith fix a damaged ignition switch?

Yes, a qualified automotive locksmith can diagnose and often repair or replace both the mechanical ignition lock cylinder and the electrical ignition switch. They have the tools to extract broken keys, re-key cylinders, and program new keys on-site.

Is it possible to repair an ignition cylinder rather than replace it?

Yes, in many cases. If only one or two internal wafers are bent or stuck, a locksmith can disassemble the cylinder, replace the faulty wafers, and reassemble it. This is often cheaper than a full replacement.

How much does it cost to get a new car key if mine is broken?

The cost depends on the car's make and model. A basic non-transponder key may cost $75-$150. A modern transponder key typically costs $150-$400 for cutting and programming by a professional. DIY is not usually an option for modern keys.

What kind of lubricant should I use for my ignition?

Use a dry lubricant designed for locks, such as graphite powder or a PTFE-based spray. Do not use WD-40 or other oil-based lubricants, as they attract dirt and will gum up the lock mechanism over time.

Why does my steering wheel lock and prevent the key from turning?

This is a security feature. If there is pressure on the steering wheel when the lock pin is engaged, it binds and prevents the ignition cylinder from turning. Wiggling the steering wheel back and forth releases this pressure, allowing the pin to retract and the key to turn.

Car Key Won't Turn in the Ignition (Troubleshooting & Fixes)

Quick Answer

If your car key won't turn, the most common cause is the steering wheel lock. Gently jiggle your steering wheel back and forth while lightly trying to turn the key; this usually releases the lock. If that fails, your key or ignition cylinder may be worn. A simple lubrication might fix it. For a worn key, a new one may be needed. Professional repairs, like fixing a stuck tumbler or replacing the cylinder, typically cost between $75 and $800, depending on the complexity, parts, and your vehicle's make and model.

Common Symptoms

Key won't insert fully into the ignition cylinder.

Key inserts but won't turn to the 'ACC', 'ON', or 'START' positions.

Ignition switch feels loose or wobbly.

Steering wheel is locked and the key won't turn.

Car won't start despite the key being inserted.

Possible Causes

Worn out or damaged key: The ridges and grooves on the key can wear down over time, making it difficult for the ignition cylinder's pins to recognize it.

Damaged or worn ignition cylinder/tumblers: Internal components (wafers/tumblers) inside the ignition cylinder can get stuck, bent, or worn out, preventing the key from turning.

Debris or foreign objects in the ignition: Dust, dirt, or broken pieces of a key can obstruct the cylinder.

Steering wheel lock engaged: If the steering wheel is turned hard to one side after the car is turned off, the steering wheel lock can engage, preventing the key from turning. This is a security feature.

Vehicle's battery issues: While less common for the key *turning*, a very low or dead battery can sometimes interfere with electronic ignition systems.

Problem with the ignition switch mechanism itself: Internal electrical or mechanical failure beyond the lock cylinder.

Step-by-Step Diagnosis

Step 1

Jiggle the steering wheel while turning the key: Gently apply pressure to the steering wheel left and right while attempting to turn the key. This often disengages the steering wheel lock.

Step 2

Try a spare key: If a spare key works, the original key is likely worn or damaged.

Pro tip: Note the battery orientation before removing it. Most CR2032 batteries have + facing up.

Step 3

Inspect the key: Look for any bends, cracks, or excessive wear on the key blade.

Step 4

Inspect the ignition cylinder: Look for any visible damage, foreign objects, or obstructions inside the keyway using a flashlight.

Step 5

Apply a small amount of lubricant: Use a non-greasy, an-silicone based lubricant (like graphite powder or a specialized lock lubricant, NOT WD-40) into the keyway.

Step 6

Check for power and shifter position: Ensure the car battery isn't completely dead and the gear selector is firmly in 'Park'.

Pro tip: Note the battery orientation before removing it. Most CR2032 batteries have + facing up.

When to Call a Professional Automotive Locksmith

If the spare key also fails to turn in the ignition.
If applying lubricant and jiggling the steering wheel doesn't resolve the issue.
If the key is bent, broken, or appears visibly damaged and you don't have a spare.
If you suspect internal damage to the ignition cylinder or switch.
If the key is broken off inside the ignition cylinder.
If you're uncomfortable attempting DIY diagnostics or repairs, as forcing the key can cause more expensive damage.

Prevention Tips

Avoid hanging heavy keychains on your car key, as this can wear out the ignition over time.
Avoid using your car key for other purposes (e.g., opening packages, prying things).
Be gentle when inserting and turning the key; avoid forcing it.
If the key starts to feel stiff, apply a specialized lock lubricant before it becomes a major problem.
Have a spare key and check its functionality periodically.
Avoid turning off the engine with the steering wheel under tension to prevent the steering wheel lock from engaging forcefully.
