Santro bumper antenna error

I'm having strange issues with my 2020 Hyundai Santro, gasoline engine, with 146896 km. I'm getting a bumper antenna error. Now unlocking/locking is faulty, and the engine won't start without the key in the ignition. Could this be the antenna?

A 2020 Hyundai Santro owner experienced a "bumper antenna error," leading to issues with unlocking/locking and starting the engine without the key in the ignition. The problem was suspected to be related to the antenna or its wiring, potentially affecting the car's immobilizer or central locking system. After ruling out battery issues, it was suggested to have a workshop diagnose the wiring and antenna module. The issue was confirmed to be a defective cable connection to the bumper antenna, which was repaired.

Wow, bizarre! An antenna causing all that? I'm skeptical. Did you check the car battery? Low voltage causes weird electrical issues in modern cars. Is the error message specifically the 'bumper antenna' or a generic antenna error?

I understand the skepticism, but the battery voltage is fine. The error message specifically refers to the bumper antenna. My diagnostic tool pinpoints it. Any further suggestions?

Okay, if the error explicitly mentions the bumper antenna and the battery is ruled out, it seems like the antenna or its wiring. Given the locking and starting issues, the antenna system is interfering with the car's immobilizer or central locking. Probably a defective cable or plug connection. I'd recommend a workshop to diagnose the wiring and antenna module.

Thank you for confirming my suspicions and suggesting the workshop! It was a defective cable connection to the bumper antenna. The repair cost me 95€. I appreciate your help!
