    Perfect as described, fast postage, thank you! ? x

    Prima verkoper.

  3. Marcin G.

    I was sceptical about the device because I know that £ 400 is cheap for a key coder, but the device has already earned itself. I programmed 2 keys for VW Golf and for Ford Transit. I would pay more for a car key locksmith service than for this device. Thanks
