Key light blinks after keyless bypass install

Tags: #ecu · #aftermarket

An improperly installed aftermarket keyless-entry bypass module (обходка) can cause the ECU to interpret the vehicle as compromised. Symptom: the key warning light blinks continuously on the dashboard despite the key being in the vehicle, even after the engine starts¹. Fix: briefly press the power button on the steering column to reboot the vehicle's systems. If the warning recurs after the restart, it indicates an installer error in the bypass wiring, not a deeper fault².
