Indeed this is coved in main-dealer bulletin i shared in post long time ago

1) i remove battery from working key and test the emergency start procedure to ensure ign switch is working

I have Nissan Qashqai j11 2014 with dangerous BCM and emergency start does not work. What is the reason?

I would do power reset or look for remote starter install

When they install remote start, they tend (most I’ve seen) to cut factory antenna wiring and tap into a bunch of places, to emulate “valid key in ignition”. All that have to be restored to original to regain emergency start functionality and only then key learning will have a chance to succeed. If you would attempt it now the car will not learn any keys and will stay at where it is until fixed.

Good to be back, logged in again.
(However been here all the time, every day. But not logged in (because of some login problems - PC related).

I would think there would be a market for a bench kit solution.
Like BMW, MB - Kessy cayenne/Toua bench kit.

Someone, should develop a kit.
And at the same time.
Do a research, how to make these modules play together again.
Firmware upgrade/downgrade. - Reset - Virgin - synch - Add new ECU

Maybe ELV emu -ON/Off (Test environment).
Antenna keyless module - start button
Synch BCM against ECU

Develop a unique software.
Or just implement, in whats there already.

I think this would be much appreciated, probably also by dealers.
Since I know, they also have these problems.
And also all other workshops around the world.

Would be a hole lot of money saved, for customers and other parts involved.
Warranty etc.

Well the good and bad news is the model(s) in question only lasted less than 10 years, and they've been replaced with entirely renault based platforms.

I have fitted probably a hundred emulators to cars with a defective BCM by locksmiths in many European markets, and no customer has ever minded having an emulator instead of a key.

Building a platform is of course possible, but in practice the locksmith customer always chose the emulator over repairing the original BCM - because of the price.

didn't think BCM can be repaired - as that's why so complicated/expensive

but if your saying steering lock emulator solves this issue then great
