What To Do If Your Ignition Barrel Is Jammed or Won’t Turn
Mobile Auto Locksmith Guide – Luton, Dunstable & Surrounding Areas
Discovering that your ignition barrel is jammed or your key won’t turn is a stressful situation, especially when you’re trying to get somewhere on time. This issue is more common than most drivers realise, and while it can affect any make or model, the good news is that it’s often a straightforward repair for a professional auto locksmith. Acting early can prevent expensive damage and get you back on the road quickly.
Common Reasons Your Ignition Barrel Gets Stuck
1. Worn or Damaged Key Blade
Daily use slowly wears down the key blade. If the cuts lose their definition, they no longer lift the wafers inside the ignition correctly, causing it to jam.
2. Steering Lock Engaged
Turning the wheel after removing the key can lock the steering column. This puts pressure on the ignition barrel, sometimes making the key feel stuck.
3. Debris or Contamination Inside the Ignition
Dust, metal shavings, or even tiny bits of dirt can prevent the wafers from moving freely.
4. Internal Ignition Failure
Worn wafers, broken springs, or general wear can cause the barrel to seize up.
5. Immobiliser or Electronic Faults
If the key turns but the car won’t start, the issue might be electronic rather than mechanical.
Quick Checks Before Calling a Locksmith
✔ Gently Wiggle the Steering Wheel
Turn the wheel slightly left and right while trying the key. This releases tension from the steering lock.
✔ Try a Spare Key
If your spare key works, the original blade is likely worn.
✔ Check the Barrel for Blockage
Ensure the key enters smoothly. If not, debris might be inside.
Avoid WD-40 or oil — they make the issue worse over time. Use silicone spray only.
✔ Ensure Automatics Are Fully in Park
If the selector isn’t fully in “P”, the key may not turn.
When to Stop Trying
If the key still won’t turn after a few gentle attempts, stop immediately.
Forcing the ignition can cause:
-
a snapped key
-
broken wafers
-
total barrel failure
-
much higher repair costs
A trained auto locksmith can usually fix the issue far quicker and without damage.
