Just wondering, if I have a fabia remote flip-key with a dead battery, can I just split it like this, and swap in the good bottom end with the battery on to the key blade for the car? I assume the transponder is in the key part, not the button part? This is a spare good key I have which is not coded to any car at all at the moment

Have never been in this situation before despite owning fabias since 2001!

you'll need to swap over the circuit boards aswell, Jason as they are coded to the remote central locking, the transponder is for the ignition.

The circuit board is only held in by one plastic tab at the bottom, it can be prised off easily enough.

Ah of course. I might just try and get the battery out. How the hell do you split the button bit? Doesn't seem obvious to me looking at it.

Ohh, scratch that! I just got a fingernail in and managed to get it apart. Now can get the battery out Aha, its a CR2032 3v thing. Fairly common from memory.

yep, there's a small gap (to the left on the pic) where you can twist it to open, then swap the battery. FYI, under the Skoda logo there is a small Phillips head screw to seperate the two halves of the blade part.

Cheers - not necessary to do that in my case.

Hoping once I stick the battery back in the remote fob will simply work properly again, and I can replace the fuse for the alarm siren, as the owner took it out due to having to use the key in the lock to open/close.
