Thread: Key Code Lockout

Hi Mate

Do you have your EKA code? That's probably what you need

Steve

Was led to believe that '95 didn't have an EKA code implemented.

I think they all had EKA but some other stuff was added through the years

It might be worth trying one of the generic codes mentioned here

the key code lockout is caused by the becm thinking the car is being stolen, too many attempts at the eka or the signals coming from another source (broken door lock, or out station etc).
it wants you to leave the ignition on (position2) until it clears, usually 20 to 30 mins (it will also need a power source as the battery will normally go too flat in that time)

Still no progress.
I'll summarise here for my benefit mainly, and hope the collective brains trust may be able to assist.
So, 'engine disabled, press remote' on msg centre when trying to start. Press remote - no change.
No CDL and attempts to re-sync fob all fail. Tried the 1515 generic (US) EKA and this prompts Key Code lockout. Key fob blinks and outputs pulses on 315 MHz.
Nanocom reads the three digit security code in EMS, but will not let me write it to BECM showing "Unable to start communications with ECU' error. Have put EMS into 'security learn' mode and cycled ignition with no joy.
It appears I need a BBS Sync-Mate to write some code back to the BECM so EMS can 'learn' it. How it communicates when Nanocom can't, I don't understand so I'm reluctant to dive into that straight away.
It seems the BECM has locked me out and there is no way to start the re-learning process of key fob codes and EMS-BECM code exchange.
TIA

So, question is: Will a Sync-Mate talk to a BECM which a Nanocom Evo can't communicate with?

is this any help?

In my owners handbook it specifically states that the EKA ois not for the Australian market. However, when i rang my local LR dealer they were able to provide me with the unique code for my car. That was around 5 years ago. I have since used the code on many occasions after parking near mobile phone towers.

Hi

as far as I understand it;

"engine disabled, press remote' on msg centre when trying to start."

Every time I have this on my car I have to use the EKA code to get things going again.

"It appears I need a BBS Sync-Mate to write some code back to the BECM so EMS can 'learn' it."

I only needed to do this when I changed the ECM. I don't think this security code is related to the EKA and "engine disabled" stuff.

As Rupert has stated the "Key code lockout" is when too many attempts at the EKA have been made

So it looks as if you need to find out what your EKA is
