B1352 on 2021-2025 Kia K5 — Ignition Key-In Circuit Failure
1 vehicles · 1 makes · $10-$400 repair
Most Reported On
B1352 is an OBD-II diagnostic trouble code meaning “Ignition Key-In Circuit Failure.” B1352 indicates a failure in the 'key-in ignition' circuit, which is how the body control module (or instrument cluster) detects whether the key is physically present in the ignition lock cylinder. This circuit drives the key-in/headlamp-on warning chime and related reminders. A fault means that detection is unreliable, which can cause chime issues and, on some Ford/Jaguar applications, contribute to no-crank or theft-system concerns. It generally won't leave you stranded but can drain the battery if the chime or related logic misbehaves. This code is most commonly reported on 2021-2025 Kia K5, with repair costs ranging from $10 to $400.
