A key that won't turn or gets stuck often points to a worn ignition cylinder. A car locksmith can repair or replace the cylinder and rekey it to your existing key.
A locksmith first checks whether the fault is the ignition cylinder or a worn key, since a rounded-off key can mimic a failing ignition. Worn wafers, debris, and internal wear are common causes of a hard-to-turn ignition. Correct diagnosis avoids replacing parts that are actually fine.
When a cylinder must be replaced, it can be rekeyed so your current key still starts the car, sparing you from carrying two keys. On vehicles with an immobilizer, the work may include matching new components to the security system. A mobile car locksmith handles both the mechanical and electronic parts of the repair.
