hi,
that is the immobiliser/cdi lost the code from the key if you still have both keys you can try recoding it but this doesn't always work. if it doesn't then you will have to buy another one, if you buy second hand you will need the ignition barrel and key, but you can buy them without the immobiliser so it is just a cdi unit so you'll never have this problem again. if you need any help or advice on this just get in touch and i'll happily do my best for you. my e-mail ruairidh_15@hotmail.co.uk
