Ignition Repair & Replacement: What's Actually Going Wrong Inside Your Cylinder
Most drivers assume a stiff or unresponsive ignition is a battery or electrical problem, but the fault is overwhelmingly mechanical. An ignition cylinder contains a set of spring-loaded wafers or pins — the same fundamental principle found in a mortise lock or a door knob lock — that must align precisely with the cuts on your key before the cylinder can rotate. Over tens of thousands of turn cycles, those wafers wear down, the key's cuts wear down, and the two stop aligning cleanly. The result is a cylinder that catches, requires wiggling, or refuses to turn at all. Heat and dust common to Central Texas summers accelerate this wear considerably.
Georgetown Locksmiths technicians begin every ignition service call with a physical inspection of the cylinder, the ignition switch it connects to, and the key itself. Worn keys can often be decoded and cut fresh on our mobile key-cutting equipment, resolving a 'bad ignition' complaint without touching the cylinder at all. When the cylinder itself is the culprit, we assess whether re-pinning and lubrication can restore function or whether a full ignition cylinder replacement is the correct path. We stock replacement cylinders for a wide range of domestic and import vehicles — Ford, GM, Toyota, Honda, Jeep, and more — so most jobs are completed in a single visit.
