Hello to all!! I'm needing help with my 2000 disco 2. This is my first time owning a luxury car like this and I'm proud to own my disco 2 . My question is...? My car is locked I tried to put my key in driver door and key did not want to turn either way. I tried to open it with the slimjim and still nothing realized my doors and everything are automatically so my dumb self broke my little window and got in .

I wanted to see if I can do anything to unlock it without the eka code since my fey doesn't turn either way in the driver door. My key fob doesn't work as well. What can I do only had her for 6 months land rover dealer is 2 1/2 hrs for me don't have much money to get it towed and fix it in San Antonio . Please help me!! Thank you for taking the time to read this!

It sounds like your Disco has suffered from a know problem sometime in the past where the barrel on the ignition switch/steering lock tends to jam up and a previous owner changed it. Now somewhere along the line the key for the door lock has been lost.
While the fob is working, there's no need to be involved with the door lock usually.
You'll need to get your fob repaired or replaced; have you tried a new battery in it?
The vehicle probably won't start because you have to disable the security system by unlocking the driver's door either with the fob or by using the EKA.
Then you're going to have to get those locks looked at, maybe a locksmith close to where you live. And get the window replaced.
