Peugeot 508 key battery warning
Summary of the thread
A 2020 Peugeot 508 hybrid displayed a 'key battery low' warning, causing keyless access to fail and unlocking to become erratic. The likely cause was a dead key fob battery. Replacing the key fob battery resolved the issue, but it was suggested to check for any stored errors to ensure no other problems exist.

Thanks. You only changed the key battery? That fixed it?

Yes, a new battery in my BMW key fob solved it. But with the stored error in your Peugeot, maybe get it checked after the battery swap to be sure there aren't other problems.

New key fob battery (37€) and everything's working. Thanks for the suggestion!

I had a similar problem with my 2018 BMW 5 series. The key fob acted up, and I got a low battery warning. I thought it was a car electrical issue. Have you tried a new key battery?
