When the ignition is past repair
Most ignition calls end in a repair: a cleaned and lubricated cylinder, a fresh key cut to code, or a steering lock reset. That work lives on the ignition repair page. This page is for the other outcome, where the part itself is finished and the only honest fix is to replace it. These are the signs that put a car on this side of the line:
- The key turns with no resistance and nothing happens. The wafers inside the cylinder are worn to the point that the plug no longer engages the key, so a freshly cut key changes nothing; there is nothing left for it to grip.
- Almost anything turns it. A cylinder that a flat screwdriver would rotate is no longer a lock, and it goes.
- The cylinder has been attacked. A theft attempt that punched the lock face, snapped the plug or twisted the housing leaves nothing to rebuild. The blade-key Kia and Hyundai models from the second half of the 2010s and the Subaru WRX are the cars we see most often in this state.
- The key goes in and stops partway, every time. A wafer has jammed sideways or broken, and once the second or third wafer has gone the rest are close behind it.
- The key turns, the dash lights up, and there is no crank at any position. With a good battery and starter, the electrical switch behind the cylinder has failed, and a switch is swapped as a unit rather than repaired.
- The engine dies over bumps, or the accessories cut in and out. A switch losing contact internally. It is replaced, not adjusted.
A key that works the doors but has to be wiggled in the ignition usually still sits on the repair side. A key that no longer turns anything, or a cylinder that turns for everything, is on this side.
