I've always had issues with Duracell so use energiser , sometimes takes a couple of start/stops for message to clear though .

Just thought I would I post this up just in case anyone had problems with the low battery warning still showing after key fob battery replacement. I changed mine today and it was still showing battery low on the dash, so I pressed the lock button on the key fob with the engine running and the warning along with yellow triangle went straight off. Hope this helps anyone who still gets the warning after battery replacement.

I did try this yesterday ( locking the doors with the engine on ) and when I use the key buttons, it does that "error" bleep and unfortunately the warning message and yellow warning triangle still appears, I think I have now got use the warning beep and warning sign.. any other ideas welcome... I need more help than most...sorry !!

Hey Muppet I did it with drivers door open, engine running and after I pressed the 'ok' button to clear message so the yellow warning triangle stayed lit, then pressed the lock button. The key fob was on my knee so I'm not sure if it was because it was near the sensor down by the steering wheel column. Worth a try.

Thanks BB, tried all those but to no avail, appreciate the suggestions though...cheers !! I need more help than most...sorry !!

That's rather bizarre how it worked on mine and not yours. I only guessed it by pushing the the lock button and it worked. You could try pressing other buttons if you not done so already.

I know this doesn't help but I always change the car key batteries sat in the car, and check it's working fine before I get out. Been caught out a few times over the years.

Usually it's the battery not seating properly so it's like struggling on power, a bit of corrosion or lost spinginess in the contacts perhaps, try spinning the battery in it's holder or wipe the contacts with a bit of dry nylon scrubber & contact cleaner.
