A broken key in the lock cylinder is annoying, but it happens more often than you might think. But don’t worry, with a little patience and the right know-how, you can remove the lock cylinder even with a broken key inside. This article will show you step-by-step how to proceed and what options you have.
Understanding the Anatomy of a Lock Cylinder
Before we tackle the removal, it’s helpful to understand how a lock cylinder works. Inside the cylinder are small pins that are pushed into the correct position by the corresponding key, allowing the cylinder to turn. If the key is broken, the pins block the mechanism.
Ways to Remove the Broken Key
1. Trying with Household Items
Sometimes broken keys can be removed with simple household items:
- Lubricant: Spray some penetrating oil or WD-40 into the lock cylinder. This can help loosen the key.
- Tweezers or Needle-Nose Pliers: Carefully try to grip the broken key part with tweezers or needle-nose pliers and pull it out.
- Coping Saw Blades: A thin coping saw blade can sometimes be slid under the broken key and used to pull it out.

2. Calling a Professional
If household remedies are unsuccessful, you should consult a professional, i.e., a locksmith or car mechanic. They have special tools to open the lock cylinder without damage and remove the broken key.
“Especially with newer vehicles with electronic immobilizers, we strongly advise against DIY attempts,” recommends Michael Wagner, master mechanic at Auto-Wagner in Munich. “An improper removal attempt can lead to expensive subsequent damage.”
Removing the Lock Cylinder – Step-by-Step
Once the broken key is removed, you can proceed to remove the lock cylinder. Here’s a guide for the most common vehicle models:
- Disconnect the Battery: To avoid short circuits, disconnect the vehicle’s battery.
- Remove Trim Panels: Depending on the vehicle model, you may need to remove trim panels in the door area to access the lock cylinder.
- Loosen Fastening Screws: The lock cylinder is usually secured with one or two screws. Loosen these screws.
- Pull Out the Lock Cylinder: Gently push the lock cylinder from the inside outwards. You may need to slightly turn the key at the same time to unlock the cylinder.
