My GF's new (to her) VW Polo '04 did not come with
remote central locking, which is annoying, it does have central locking by putting the key in the door though.
After doing a little research it seems it is not that difficult to retro-fit the remote control unit to the existing central locking.
You can either go two routes to do this:
1. Find a scrapped VAG car with the correct remote central locking controller in it, do some code hacking to match it electronically with your car ECU and replacement key, then fit the physical control box.
Quite a lot of learning and potential to break the car's ECU.
2. Buy a box such as below which has already been coded to the key and is ready to fit. All you need to do is get the key cut to match your car as the 'blades' are blank at the moment and take the glass crystal from the existing key and put it in the new key (for the immobiliser I think).

So it is set-aside to fit remote central locking.
QuestionWhen I order the part from eBay, the seller will have our address. IS there anyway they can or could have duplicated the keys to allow access to the car?
I am being super suspicious here, but I have not fitted remote central locking before and I am not totally sure what is going on.
As I understand it, even if they did have spare keys 'coded' to that remote receiver, they would not be able to get into our car without having the glass crystal from our existing keys? Is that correct?
