Then this guy is your saviour!! 😃 😃

For £15 (or a best offer of £10 in my case) he offers to take your faulty key and solder 2 new buttons and a new battery carrier onto the board!
What a service! I sent mine over to him on Saturday, had the key back on Wednesday and is working 110%!
Bear in mind, vauxhall where going to charge around £150 + VAT for a new key!!
(I feel this may need to be made a sticky!)
