MY 14 Defender Key Fob Battery change

[tonyci]

Hi all. I am currently away from my defender and handbook. I am about to head off for a month and need to change my remote battery can anybody please confirm that the correct battery is CR2032.
is there any defender quirks in changing the battery or is it just a case of old out new in ?.
thanks for any help.
Tony

[Marty90]

that's the correct number. straightforward swap.

[tonyci]

Thanks, I thought I read somewhere you had to change the battery in the car, which does seem a little strange

[Chenz]

That's so the gremlins don't lock you out:o

[alien]

The procedure is in the owners hand book.
You only have short time to do the swap after a lock-unlock procedure due to the way the alarm works.

Thanks. I will have a read when I get back to my Defender.

There it is...

Just out of curiosity/ignorance when would you need the EKA code?

[roverrescue]

Just to clarify that pdf description LR were a little vague
At end of batt change
You press lock four times to initialise the fob ... Is that with door open or closed ?

I would expect it's with the door shut or it will not arm and give a beep on the horn.
I'd be doing it with the window down, just incase Lord Lucas-Prince of Darkness makes an appearance.

Just out of curiosity/ignorance when would you need the EKA code?

When your key fob has been stood on by an elephant, swallowed by a wild animal, dropped into a flooded river, stood on by a drunk camp cook, or the passive detector loop around the ignition key barrel, or any other component of the immobilizer conspires to impede your ability to un-immobilize .... You could use your EKA to avoid a flat-top ride.

Particularly helpful function - specially if you are deep in the wilds where no flat top can get in...

Simply avoiding an embarrassing "breakdown" which is related to just being unable to un-immobilize.

Thanks, that is a nice explanation.
So, where on earth is this Code hiding because is not in the manual or in any other paperwork?

The Defender does not have an EKA Sir, according to most dealers. But it does so just contact this gentleman:

He will send you the 4 digit code. :)

Supposedly handed over with the vehicle. I never got mine with the vehicle. Started asking a couple of years ago and the journey went like this:
- Land Rover Malaysia (LRM) said they'd have to ask LR UK.
- LR UK don't have records for vehicles shipped out CKD for assembly overseas, so would enquire of Lord Lucas to see if they had it on file
- Lucas also don't keep a record.
- Asked why cant LRM just hook up their LR diagnostics computer, and read the EKA from the security module. Apparently Nanocom devices can do that.
- LRM diagnostics computer couldn't read the EKA
- bought myself a Nanocom. It wouldn't, and still won't, even talk to my ECUs at all. Useless paperweight for 2yrs I have owned it.

- LRM and LR decide to replace all my ECUs (engine, security, instrument) with new, with known EKA.
- change of plans... Some new idea how to read my EKA with LR diagnostics
- didn't work
- waiting on new ECUs

Throw in a few months between every step above and it's taken more than 2yrs to still not yet have an EKA for my vehicle.

(And I really want it... Cos we do go deep jungle, where elephants, drunk cooks, and tigers/bears/panthers roam)

Typical of many dealers, they are good at using apprentices only to make things worse than they were without fixing problem.
They couldn't even reset the Ecu after service and kept on getting service message.[emoji16]

The service message you can reset yourself.... No tools needed.

1. Ignition ON, press both brake and accelerator pedal full down for 15 seconds

2. Oil light starts to flash.

3. Turn the ignition OFF and leave it for a minute

4. Job done.

The MY15 hand book I have is different to the one Tact put up. And my fob looks different to the one in the picture in the pdf.

In mine there is no note about having to change it inside the vehicle

I have 3 steps in mine

To Replace the battery:
1. Remove the cover, by sliding it in the direction of the arrows
2. Use the key blade of the black key to separate the key fob body
3. Fit a new and unused CR2032 type battery (available from a Dealer / Authorised Repairer) with the positive (+) side upwards.

There is a note about not touching the battery and another note if the battery is not new then the low battery warning will not extinguish.

There must have been a change in the FOB at some point.

Cheers,
Col.

Probably safer in Malaysia to stay in the vehicle, as Tact noted all those wild animals & elephants! :)

...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).

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?

[ProjectDirector]

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.

[tonyci]

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

[tact]

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"

[ProjectDirector]

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)

A little confused now as to whether mine which I thought was decimal (July 2015 build) should now be Hex, especially as last 2 digits are over 60. So I did run my EKA through this converter & it gave me a 4 digit hex #:

Nothing is ever simple with a Land Rover. :(

You must convert two at a time. So, convert first two and then last two, put nos together and that's the answer.

[AndyG]

Damn,
I thought i was so clever getting my EKA code of 4 digits for my MY15 from the dealer with no fuss, and carefully memorized it, and now it could be Hex :confused: :mad: :D
Another unique LR trick to trip us over.

I dont think the EKA code is something you want to "test" on your car and FU

Couldn't agree more.

Mine must be already converted as if I use just the first pair I get _E, which can't be correct!

I would say yes

[tact]

Try it out. What's going to break!? Only way to know you got it right and know how to use it right.

Just have pity on neighbours - the alarm should go off in the process of using your EKA.

[Avion8]

I'll try it out next time I'm at the dealers! :)

Got the Key fob of my 2016 defender wet with salt water

........rinsed it in fresh water dried it with tissue ....then sprayed it with Wd40 Contact cleaner

NO GOOD ....LOOKS DEAD ...

if I want to get a new one what are my options ....LRwill charge like a wounded bull
......is there an aftermarket solution ......
much obliged for suggestions .......

[DiscoMick]

Try changing the battery. But make sure to take the fob out of range of the vehicle before pulling the battery.

Since this topic has resurfaced - I needed to change the battery in one of my FOB's - and in the MY15 Defender it was as simple as the three steps in the manual.
