Why Vehicle Ignition Cylinders Fail — and What We Find Most Often in Floresville
Floresville sits in a stretch of South Texas where summer heat regularly pushes past 100°F, and that climate accelerates wear on plastic wafer stacks and metal tumblers inside ignition cylinders. Add in fine caliche dust common on the county roads connecting the city to surrounding Wilson County ranches, and you have the perfect recipe for a cylinder that binds, sticks mid-turn, or accepts the key only in one specific orientation. We also see a high number of vehicles with high-mileage ignitions — trucks and work vehicles that log serious miles between Floresville, Pleasanton, and San Antonio — where the key has physically worn the cylinder's wafer stack to the point that any slight key variation causes a no-start.
Other common causes include broken or bent wafers inside the cylinder, a shear pin that has fractured (common after an attempted theft), and corrosion that freezes the lock plug in place. In each case, the right response is a proper inspection, not a generic 'replace everything' approach. Our mobile technicians carry a full inventory of replacement cylinders and components for domestic and import vehicles, which means most repairs happen in a single visit — right where you're parked.
