Key Fob issue

ok so my official answer as someone who had the same problem is...

Take the sticker off the battery.

Then look at the battery AGAIN - for the parts of the sticker you missed, that are still there and blocking contacts :)
 
Feck me I get sooo annoyed at Muricans & Jag-wire.
What the eff is a Jag-wire.
A Jag-wire is one of those thin cylindrical conductors with a colour-coded plastic sheath around it, typically found in Jaguar cars. Apparently not a good idea to mess with Jag-wires (their electronics are already sensitive enough, thank you very much).
 
If it is a Duracell CR2032 battery, give the side a quick taste with your tongue. If it's bitter, then that's your problem. Duracell implemented putting a bitter tasting compound on the edges of the battery to prevent babies and small kids from putting it in their mouths and possibly swallowing it. Just take a cloth dabbed with methylated spirits and wipe the sides of the battery to remove the bitter tasting compound and try the battery again.

I pronounce it like Yoda would

Jag, you are

Duracell is especially annoying it has an outer plastic case and a center sticker and a sticker on the outer circle and they’re transparent.

Failing that. Ensure you bought the right batter size and voltage.

They’re not specific to one battery, so any should work. However if it had a lithium and you don’t put a lithium in, or vice versa, it may also be a problem. As some battery sizes come in that size as a normal battery and a lithium battery.
 
Here is an idea for a new forum game - match the forumite to their car:thumbsup:

Either wrong spec of battery (not wrong brand) or installation error.

Is there an led on the key that lights up when you press the button?

Starting the car is independent of the battery, that's done via a transponder powered by induction from a coil in the ignition slot
 
So, its finally working, just before I went to Sandton to collect the Sony battery it decided to work. Out of its own. Both remotes at the same time. Thinking it might be some signal interference or jamming. Time for the conspiracy theorists to jump in - I live right next to a Rain 5G tower. Also was the first time this week I went into the office when it started working at the office just as I was about to leave.

The sound of the doors locking was like music to my ears.

$%^&* it, I'm out.
