XC40 Keyless Entry Failure

I've got a 2023 Volvo XC40 electric with about 240k on the clock. Recently, I've been getting a 'key battery low' warning. Now the keyless access is completely gone, and there's an error stored. Unlocking and locking is a pain. Seems like the battery in the key fob is dead, anyone else experienced this?

Yep, had the same thing happen with my XC40. Keyless entry just stopped working one day. Did you also notice it struggling to start the car sometimes, like it wasn't properly detecting the key?

No starting issues so far, just the keyless entry and the error message. Did replacing the battery fix it for you, or was it something more serious?

Replacing the battery didn't work, unfortunately. I ended up having to take it to the workshop. They ran some diagnostics, re-synced the key, and replaced the battery anyway. Cost me about 40€, and it's been fine since.

Thanks for the info. Sounds like I'll be heading to the shop then. Just got it back, new battery and resync, 37€ and works a charm again.
