The dealer gives you 2 keys, one Master key and one normal key, If you have lost the master key then you will need to have the car, V5C or the spanish Reg document & your proof of I.D and address before the dealer will do anything to help you with a new key. This WILL for sure be quite costly as well.

 

There are other places that can do you a new key for a little less cost, BUT, they have to do the same thing as the dealership would.

 

With these new cars there are no tricks to help you out as they are coded to the vehicle's ECU.

If you get to the point of the immobilizer not disarming then there is an emergency start-up proceedure in the owners hand book that came with the car from the dealer.

 

When you need a new key, the dealer has to order the key blank for your car. When they get it and your car and then start the coding proceedure they have about 60mins to do it and only get 2 goes at it.

After the 2nd try they have to scrap the key and get another one.

 

They need the car there as they have to plug it up to the diagnostics computer to access the car's ECU and then access the correct system in the ECU to allow them to start the coding proceedure.

 

It is a very daunting job for any mechanic as you have to slowly read the proceedure, step by step and make sure you do everything as it says so you get it right the first time.

 

Hope this is of some help to you.
