Yaris Key Fob Battery

I've got a weird one happening with my 2022 Toyota Yaris, gasoline engine. I'm getting a 'key battery low' warning constantly. Keyless entry is completely dead, and I even pulled the codes – there's an error stored related to the key fob. Unlocking and locking is super unreliable now too. I'm assuming it's the battery, since the car only has 31123 km, but is there anything else I should check before I go tearing into the key fob? I did try the spare key and same issue!

Dude, I had the exact same thing happen with my Yaris! Sounds like a dead key fob battery to me.

Seriously? Just the battery? I was hoping it wasn't something more sinister. Did yours give you a bunch of headaches before it died completely, or was it pretty sudden?

Pretty sudden, honestly. One day it was fine, the next, nothing. I tried replacing the battery myself, but it didn't work. Just took it to a shop and they sorted it out. Quick and easy, but worth the cost for convenience.

Good to know, thanks! Ended up just taking it to the workshop, as you suggested. 37€ later and it's all sorted! It was indeed just the battery in the key, but they also cleared the error code. Appreciate the advice!
