Seat Formentor Key Battery Issue

I'm getting a weird error with my 2020 Seat Formentor gasoline. I'm getting a 'key battery low' warning. Keyless access isn't working anymore, and there's an error stored in the memory. I have 142363 km on the clock. Unlocking and locking is also unreliable. Think the battery is just dead?

Summary of the thread

A 2020 Seat Formentor owner experienced a 'key battery low' warning, leading to unreliable keyless access and unlocking functions. The issue was identified as a dead key fob battery. Replacing the battery resolved the problem, restoring full functionality to the keyless entry system. If similar issues persist after a battery replacement, further investigation at a workshop may be necessary.

I have a Formentor as well. I experienced something similar recently. The car started displaying a 'low battery' warning for the key fob. Have you tried replacing the battery in the key?

So, your keyless access also stopped working? And the battery replacement fixed it completely?

Yes, the keyless access stopped functioning correctly. I could still start the car, but the range was severely limited, and the error message was persistent. Replacing the battery resolved all the issues I was facing. If replacing the battery doesn't solve your issue, you might need to consult a workshop to check for other potential problems.

It was indeed the fob battery. Got it replaced for 37€ at a local shop. Keyless entry is working again. Thanks for your help!
