Koleos Key Battery Low Warning

I'm experiencing an issue with my 2014 Renault Koleos diesel. The dashboard says 'key battery low'. Keyless access isn't working, an error is stored, and unlocking/locking are erratic. I think it's the key fob battery, but has anyone else seen this?

I have a Koleos and I've had key fob issues. Was the error code a B1051 or something? Did you try a new battery to see if that fixes it?

Thanks! I haven't checked the error code, but the symptoms match a low battery. When you had this, did replacing the battery solve it for good, or was there more troubleshooting?

When I had the issue on my Koleos, a new battery worked for a bit, but it failed again after a few weeks. It turned out there was a parasitic draw that was draining the battery. If a new battery doesn't fix it, get it checked by a workshop before you get stranded.

Thanks for the advice. I'll try a new battery first, and if it keeps happening, I'll take it to a workshop. A new battery fixed it. Repair cost was 37€
