Pin Code for immobilizer / key programming

[janovat]

I have the following problem:

I have bought a Berlingo Multispace from 1999 without keys and I got a new key from Citroen. When learning the key, there was a problem: The immobilizer came back after each time I turned the car off again. Since the battery of the good piece was totally down and the car was attached to the starter pack, the dude of Citroen probably meant that this is the problem.
I should come back when I have a new battery installed. They had no parking space free so I've parked the car many miles away from the citroen service.

Since I do not have the money to let the Berlingo be carried around again two ways (it is not ready to drive yet because of the registration),i am in possession of a suitable OBD2 controller to turn the immobilizer off and learn a second key.
Unfortunately I miss the necessary 4-digit pin.

Can someone help, pleaaaaaaaaaaaase?

The only way that I know to get the code is from a Citroen dealer. In the UK you need to take the documents to prove it is your car & £20.
It seems strange that you were able to add the key before without a code. Maybe your Citroen dealer already has the code?

I see you are also asking on the German forum, maybe they have a better option.

It was not me adding the key, it was the citroen dealer.

It was not me adding the key, it was the citroen dealer.

In that case, they will be able to give you the code.
