Seat Tarraco Keyless Entry Problems

I've got a 2023 Seat Tarraco with a gasoline engine and about 151697 km on the clock. Recently, I've been having some weird issues. There's an error stored in the memory, the remote unlocking/locking is acting up, and now I can't even start the car without the key in the ignition. I read somewhere it might be the bumper antenna. Anyone else had this? Is antenna replacement the solution?

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?

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.
