Yes, I did not mean and you need EKA to remove the former but "you can only enter EKA once the former is removed"
Still don't understand what is happening here either unless it is something (physically) intermittent though...
(or the system was already 'got at' somehow ?)
Ahh :) I get you.
Might need to recap what its currently doing - messages, locking etc. It should be possible to start the car with a fob with no/dead batteries, that's the point in the EKA, so something must be amiss somewhere.
Edit - Dave beat me to it!
Though I'll add - the P38 system isn't like other cars in terms of the inductive coil around the ignition barrel. On a P38 this coil tells the key to transmit as if you'd pressed a button. So the key does need working batteries and the RF receiver in the car needs to work. So if the key isn't working for whatever reason, the car won't receive the code and won't start - leaving you with the EKA.
If you disable the 'passive immobiliser' through a Nanocom etc, what actually gets disabled is the re-immobilising of the engine 60 seconds after stopping it, unless you lock the vehicle with the key, which does immobilise it. Unlocking then re-mobilises it again, assuming the door latch switches work properly.
On other cars, the key has a standalone pickup and chip in it that is powered by the inductive coil and transmits back the immobiliser code. Generally very reliable. How I wish the P38 had such a system.
