Thread: How to decode the key code on replacement Discovery 2 key?

No I haven't checked the frequency. It is supposed to be a 433MHz key for my 2003 D2a TD5. I've only had the D2 for two weeks, and the nanocom evo for one week. I didn't want to play around with the nanocom too much yet. I thought I should save the BD performance map first ? I am wary about wrecking something as the car is running really well, and there is no real manual for the nanocom's although they seem pretty intuitive. Checking the Rf won't do any harm - With respect to reading and writing settings always READ and SAVE your settings before you try to change anything especially the BCU settings - occasionally they get corrupted during a write..

I wondered if the nanocom is able to read the 6 digit code when I press the buttons on the new key? or is it only able to know that it is the wrong code for that key? The Nanocom won't tell you the code but it can detect if the key fob code is not programmed into the BCUAnd a slightly related question - the manual says to enter a 4 digit EKA code. The card that came with the car has an eight digit EKA? Do I just enter the first four digits of this?
The EKA code is four numbers they can be two digits or one digit each eg 12, 3, 14, 15 Thanks again,
Alan

The EKA code can be changed using the Nanocom I would recommend using low numbers eg 1,2,3,4 so you don't have to turn the key in the driver's locktoo many times.

Hope this helps.

Oh dear.
I have done the exact same thing, and bought a new key from USA that has no code or barcode.
I understand I have just bought a very expensive spare case and key blade.
