B1352 on Kia
Ignition Key-In Circuit Failure
B1352 on Kia vehicles indicates ignition key-in circuit failure. Au7o has documented this code across 1 Kia model — most commonly on K5. 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. Typical repair costs on Kia range from $10 to $400, depending on the specific model and root cause.
Common Causes of B1352
- •Faulty key-in ignition switch/cylinder sensor
- •Corroded or damaged wiring near the ignition switch
- •Faulty door chime or warning module
- •Loose or corroded connector at the ignition switch
- •Faulty body control module (or GEM)
- •Open or short in the key-in signal circuit

Kia K5(1 issue)
- Rear Trunk Latch Sticking and Failure to Open2021-2025
The electric trunk latch mechanism on the K5 is prone to sticking or failing to release, leaving the trunk locked. The issue is more common in cold weather when moisture gets into the latch mechanism and freezes. The trunk release button on the key fob, interior button, and exterior trunk handle may all fail to open the trunk when the latch is stuck. Some owners report the latch actuator motor failing entirely, requiring manual release from inside the trunk via the emergency release handle.
