G'day mates

I need your expertise ) After I replaced a battery in my 15 years old key fob it has stopped working. There is no chip, no immobiliser and no alarm system. I can start my car with that key and even with second straight cut key. Also I can open door via the door lock BUT I can not reprogramm it myself pulling it 6 times into ignition etc (tried all combinations you can imagine) and get it work again as well as be able to open doors remotely.

New battery, voltаge is fine 2.9V and I have not dropped key fob or something. I bought another 100% workable key fob which didnt work too. Went to local Nissan dealer and even they could not reprogramm both of them using Consult II so my guess is BCM is malfunctioned?

Question is if I buy a second hand BCM from the same model V35 2001 4 doors would it work straight away? I mean would I need to pair new BCM with ECM or something?

Cheers guys for any inputs, frustrated

 

*** may be someone is selling BCM module here I can buy?

* quick update

Apparently the reason was broken BCM the cause of that could be moisture or something as there is rubber gasket above BCM that lets all wirings go to under hood compartment. I punched a few holes there for my aftermarket gauges. Some water could theoreticaly dripped down to the comfort module but its just my guess.

I have ordered a new module from Japan that costs me $320 without shipping. You dont have to pair it with ECM just plug&play. Also BCM from Stagea is compatible with sedans 2001 years.
