What Goes Wrong: Common Causes of Ignition Repair & Replacement Jobs
Vehicle ignition cylinders endure thousands of key insertions over a car's lifetime, and wear is inevitable. The most frequent issues our Columbia-area customers call about include a key that turns freely but does not engage the starter, a key that inserts but refuses to rotate even a fraction of an inch, a cylinder that binds only in certain temperatures (a real problem during the humid South Carolina summers and the occasional hard freeze we get in January), and broken key fragments lodged deep inside the cylinder. Electrical faults in the ignition switch itself — separate from the physical cylinder — can also cause intermittent starting failures that drivers often misdiagnose as battery or alternator problems.
Damage from attempted forced entry is another category we see regularly. When a vehicle has been targeted by thieves or someone has tried to use the wrong key repeatedly, the internal wafers inside the cylinder can shear, the keyway can widen unevenly, or the anti-theft collar can lock permanently into place. In these situations, a full ignition replacement is often the more cost-effective and longer-lasting solution compared to trying to rebuild a compromised cylinder. Our technicians assess both options transparently so you can make an informed decision before we proceed.
