...and keep the windows wound up. Ground dwelling bees are to be feared as much as elephants. (the other wild things, with fur and teeth, very unlikely to encounter).

He will send you the 4 digit code.

Ok, I called LRA this morning and they gave me a 4 digit Code but it consists of 3 numbers and last digit a letter. He said they don't have anything else on their system. Is this right?

I found it, they now use hexadecimal system and they need to be converted to decimal. Confirmed with dealership service department and now waiting for LRA to validate.

I received a four digit number from LRA about two weeks ago after I emailed them asking for my EKA code.

The switch from storing the EKA in decimal to hex happened part way through 2013 or 2014 (sorry I don't remember exactly).

Don't assume that if your EKA is four nice looking, decimal looking, numbers then it must be decimal.

Eg. 1234 (if given as decimal) means you use 1234 as your EKA.

BUT if 1234 is given to you and it's in Hex then you have to convert per LR conventions:
- break the 4 digits into two pairs
"1234" becomes "12" and "34"

12 hex is 18 decimal
34 hex is 52 decimal

So your EKA is really "1852"

When LRA gave me the code was eg. "123A" (not my code) they had no explanation why it wasn't 4 digits number.
After I posted here asking about it, it occurred to me it may "coded" and realised it could be Hex as I have used in my electronics engineering course.
I converted the whole number and then called MCL service and they told me there has been a change at some stage and codes were Hex. They said that you covert 2 numbers at a time, ie with this example 12=18 and 3A=58 so code=1858.

I am not sure why they have gone Hex, maybe they are selling too many cars and this way you can have more combinations.

I assume if the last two digits in the given code by land rover is 60 and over it must already be in decimal as 60 and over in hex results in three digit codes. e.g. 60 hex is 100 decimal.

Good call. (Except it's 64hex = 100dec)

Same would apply to the first two digits and last two too. (If 64 or higher then the EKA is already in decimal)
