Keyless entry problem

[RayCroft]

Impreza 2021 : I changed the key fob battery because I got a warning that the battery was low.

Now I can't unlock or lock the doors with the fob. I can start the car by holding the fob next to the Start button, but not if the fob is a small distance away.

The other key fob works fine.

Anyone got any thoughts on what I should try?

Thanks

Ray

Are the batteries inserted correctly?

Thanks for getting back to me, but it was a false alarm - the "new" battery wasn't quite as new as it sould have been. My AVO meter checked it out at 3v, but a new new battery fixed the problem and all is now working fine.
