New owner of a Disco 4!! few questions!

I am now the proud owner of my first Landrover, a discovery 4, in Black, HSE form.
So far I am loving the new experience, being used to more smaller and sportier vehicles vx220, exige.

1st of all I have been provided with 2 keys, both identical to each other, should I not have 3 keys? or is this not the case??

Secondly, I would like to install a flip down tv/monitor on the rear roof for the kids, is this a diy or am I more likely to need an expert to carry this out?

Going through the forum I have picked up on the abbrevation "EKA". I have searched it on google but it just comes up mg rover and the likes, what is a eka code?
- Do/should I have one?


Thank you!

Pics shall be uploaded ASAP!

the eka code should be in your handbook on the security card (if it even has one)
get a pro to do the install if it's a new car,
phone the dealer you got the car off and ask em about the key and the eka code while your on
