Hey folks I have lost the chip board out of the fob for my rover streetwise/ rover 25, so the car now won’t start due to the immobiliser, I have been in contact with loads of companies and they are all wanting about £400 to sort this problem, does anyone have any advice or a cheaper way of sorting this problem? I would need a new fob with chip boar in it and to get it programmed to the car, thanks in advance for any advice
