New Vantage owner, 2006 V8 - First problem

[Cornwall1]

Help.
Just changed the battery in the key fob, as I had a low battery warning.
Now the key fob does not work, any ideas?
Yes I have fitted the battery + down as per the old one.

Try another battery.

Thanks Buster73,
Tried another battery,still no good.

Have you got the second key fob?

[Cold]

It really should be a straightforward procedure. I wonder if you've inadvertently pressed one of the buttons while fiddling?

Thanks for looking Cold.

Having looked at the car this morning,problem was the main car battery low,I checked it with a meter (reading 9v)
Car started again with a battery pack and after taking for a run remote worked.

The battery was run down as being a new owner I was opening and playing with everything on the car
and did not think about the car battery.
