Kuga key battery low warning

Sounds familiar! I had the same thing happen with my old Renault Megane. Keyless entry packed in, and it kept throwing up errors. I thought it was something serious at first, like an immobilizer issue or something. Did you try the spare key?

Spare key works fine. But how did you solve the problem on your Megane?

Well, with the Megane it turned out to be exactly what the car was telling me – a flat battery in the key! I didn't believe it at first because the car was only 4 years old, but apparently, that's a common thing. I’d suggest getting it checked out at a workshop, they'll be able to tell you for sure and replace it if needed.

You were right. New battery in the key and all is working fine again. Cost me 37€. Thanks for the tip!
