Just be carefull with Timpsons, they have buggered two blades I have provided in the past on seperate occasions - the first time I thought fair enough as it was an ebay blade but on the second occasion it was a genuine blade, they managed to totally cut through the center of the blanks. Now I don't know if this was opperator error, machine out of caliberation or just sour grapes on the part of the shop worker

There was a seller on Ebay a few months back selling new key bottoms with virgin transponders

Just avoid the ones that say "new blade fitted" as they might have been coded before

If you just need a blade there is also a seller doing blades cut to your key profile from a digital photo of your original key

- and yes it does work
