What Actually Goes Wrong Inside an Ignition Cylinder
Most drivers assume an ignition problem is electrical, but the majority of calls we handle are purely mechanical. Inside every ignition cylinder is a series of spring-loaded wafers or pins that align with the cuts on your key. Over years of use — especially in New York winters where road salt and grit find their way into everything — those wafers wear down, corrode, or break. When that happens, your key may turn too stiffly, feel loose and sloppy, or refuse to reach the start position at all. In some cases the cylinder itself seizes, leaving the key completely trapped. None of these conditions fix themselves, and forcing the key harder almost always makes the damage worse.
A worn ignition is also a security vulnerability. A cylinder that is so degraded it turns inconsistently may be susceptible to manipulation by someone who should not be near your vehicle. Addressing the problem promptly is not just about convenience — it is about protecting the car you depend on every day in one of the most densely parked cities in the world.
