I could not find anything similar already posted on here about this.

But my remote key is dead. As if the battery needs changing, but I have read in the manual that the keys is rechargeable from the ignition.

I wonder if anyone could confirm?

Guess I will just have to buy a new key.

Cars a 2006 RRS.
Thanks I work and I pay tax, a lot of tax

You could try keeping it close to the column whilst using the spare, just to check that recharge is not working (it is induction charging, not contact); taping or rubber banding them together.

I had a dead key (2005 MY D3) and revived it with a new battery. Replacing it required brute force and a soldering iron and has resulted in a non-functioning spring and a lack of waterproofing. However, it did save £100 and the time taken in ordering a new one.
