Hi all,

Weird sequence of events today.. got in my car like normal, remote key worked fine.. drove to gym and parked up for 90mins.

Come back to my car, the fob doesn't work. So i pop the outside of the handle off, use the key in the door, alarm goes off (not sure this should happen), get in, turn the ignition on and it says replace battery in key, and I drive home.

I replace the battery in my key with a new one.. it doesn't work (no light on the fob when pushing a button).

I replace the battery in my key with one from my wifes car (battery definitely has charge), it still doesn't work.

So i give up on that key.. locate my spare, try it up in my bedroom and its working (at least the light comes up on the fob when i press a button). I go down to my car, press unlock.. nothing happens.

I try sync'ing my spare with my car outside it, press unlock, manually open the door (alarm goes off), turn the ignition on (car says replace battery in key). I then turn the car all off, get out, shut the door, and.... the key no longer works, no red light on fob when i press the button.

I try two different new batteries in both my keys, original and spare.. and now neither of them even give a red light on the fob when i press a button.. its like the car has killed the keys.

any ideas for home remedies? appreciate any advice
