Car won't start

Try your other key as a first step fault trace on wether car is reading new key fob.

Hi, he brought the car private with only 1key

That's not so good is it as you say it,s happened since he had a new fob .It probably requires coding ,which would be main dealer to do this unless you know a specialist with the correct kit.

Ok thanks, do you know if the immobiliser is set, would the engine still turn over ?

If it,s reading the key ,then yes ,if not then no.as it read,s the key and then send,s a start signal to allow Cranking.I can only assume either your key antenna does not recognise the key ,or is not reading the key for some reason.advise take it to a main dealer.

Cheer for that

it will turn over it just wont fire. I cant remember whether the chip is seperate or not for that type of fob.

if you have swapped everything over and the locking works from plip then the chip must be seperate and still in old key body.Economy mode is present as battery voltage getting low probably due to trying to start car

Cheers for that, I'm going to see my dad tomorra, so if I put the old key/fob in the car it should start if the chip is in the key ?

just hold the old fob next to it when in the ignition. If it still doesnt start then you will need to get it to a dealer to program the new key

Thanks for all answers, I've found the problem........... Inside the key fob, there is a little plastic block ( which looks like a piece of old plastic just to fill the gap) well this is the chip for the immobiliser, luckily the old fob wasn't thrown away. I fitted it to the new key fob and hey presto....... The car starts.. Cheers everyone

glad you found it. on later cars it is part of the printed circuit. Thanks for getting back as not many people do.

My car turns over but won't start the horn doesn't work or central locking don't work
