Why Your Ignition Won't Turn — Common Causes Chicago Drivers Face
Chicago winters are genuinely hard on vehicles. Repeated freeze-thaw cycles, road salt, and the kind of cold snaps that turn the Chicago River into a slushy grey ribbon can accelerate wear inside an ignition cylinder. The most common reason an ignition refuses to turn is a worn cylinder — after years of use the internal wafers or tumblers wear down unevenly, creating a situation where even the correct key can no longer align the pins. A second, frequently overlooked cause is steering column lock engagement: if your steering wheel is turned under load and the column locks, the ignition cylinder binds under pressure and the key physically cannot rotate. A quick, gentle wiggle of the wheel while applying light turning pressure to the key usually releases this — but if it does not, the cylinder itself may be damaged.
Broken or worn keys are another major culprit. A key that has been copied multiple times, or one that has been used on a heavy keychain for years, can develop slight dimensional variations that prevent it from properly lifting the wafers inside the cylinder. In some cases the key snaps off inside the cylinder entirely — a situation that requires professional extraction before any other repair can proceed. Our mobile technicians carry key extractors and a full range of ignition-specific tools, allowing them to remove broken keys from cylinders on-site without damaging the surrounding column or housing.
