My key fob works but shows low battery warning even after new one fitted. It won’t open or lock the car but will work in the ignition ... if you can get in using the key! Two new batteries tried with same outcome.
Any ideas or suggestions 
My other key works fine thank goodness.

Thanks Jon
Batteries in right way and connection seems ok.
Did frustrated ever get his fixed. Sounds a bit like his later Oct 7 problem.

If I ever have to use the key saying low battery, will it keep working as it is a new battery in there, or will the car suddenly cut out if it or when it decides the battery is dead?

Battery is only used for the remote side of things,for starting etc the ism reads the rfid inside the fob..
