What Goes Wrong: Common Ignition Cylinder and Key Problems
Ignition cylinders endure thousands of rotations over a vehicle's lifetime. Over time, the internal wafers — the small spring-loaded plates that read your key's cuts — wear down, warp, or break entirely. When that happens, the key may turn with resistance, fail to reach the start position, or spin freely without engaging the starter. In colder months, Bergen County winters accelerate this wear because metal contracts and lubricants thicken, putting extra stress on an already fatigued cylinder.
Broken keys are a separate but related problem. A key that has been duplicated too many times from a copy rather than the original gradually loses sharpness in its cuts. Combine that with a worn cylinder and the key can snap mid-rotation, leaving a fragment seated deep in the barrel. Attempting to extract it with a bobby pin or superglue is almost always counterproductive — it can push the fragment further in or coat the internal mechanism, complicating the extraction and raising the eventual repair cost. The safest and most effective step is calling a professional.
