Summary of the thread
A 2023 Seat Tarraco owner experienced issues with keyless entry and starting the car without the key in the ignition. The problem was suspected to be related to a faulty bumper antenna, which affects the car's ability to detect the key's presence. After replacing the bumper antenna, the issues were resolved, confirming it as the cause.

Radio seems fine, no issues there. So, are you pretty sure it's the antenna itself, or could it be something else, like a central locking module?

While a central locking module issue is possible, the fact that you also have a stored error and issues starting the engine points strongly towards the bumper antenna. The cable or plug connection of the component is likely defective. Think of it like a chain reaction – a faulty antenna affects the car's ability to verify the key's presence, leading to the starting problem. I recommend having the antenna checked and likely replaced by a workshop.

It was the bumper antenna. The workshop replaced it, and everything is working again. The bill came to 95€ Thanks for the help.

That sounds like a faulty bumper antenna is the most probable cause. The symptoms you describe are consistent with that. Is the car radio affected, any issues with the radio signal?
