Trying to code remote key and unlocking doors

Recommended Posts

Hi guys. I’m having all sorts of problems, firstly the immobiliser is not allowing me to start the car, only intermittently but rarely and I’ve lost all communication from both my remote central locking keys. 

I thought I’d look into the key fobs first, I replaced the batteries in the 2 keys, I then tried to do a key reset. So I lock the doors, then put the key in multiple times waiting for the hazards to flash getting into service mode but on the 4th or 5th time of the key going in the central locking unlocks the doors. If I kept going there’s no sign of hazards so I’m guessing that unlocking of the doors is stopping me access the service mode.  

The car has been off road and not driven in 6 months. I just fitted a new battery. 

Any suggestions anyone?

Does anyone have any suggestions of how to program and get the key fobs talking to the cars or reset the immobiliser? Thanks 


This worked on my 350z, as it's the same era car
