if i swap my ECU will it not even start at all with out reprogramming the key? i'm just wanting to swap my ECU to see if that is the problem.

 

Perhaps a locksmith can help!

 

The RFID code from the key is stored in the ECU, so you would have to get the keys reprogrammed.

Locksmiths will program the keys in their parking lot, so find a locksmith with the best price. The drive over there, take the connector off the original ECU. plug in the new ECU and have them re-program it. Make sure you have all you keys with you.

 

is there a way to flash ECU with the RIFD as original?

I'm assuming based on your answers it will indeed NOT start.

as someone with ZERO money and income this could pricey fast.

 

To avoid playing a locksmith or dealer you can purchase Nissan Data Scan II, for roughly $62.00, then purchase a VAG COM OBDII 409.1 USB adaptor for around $15, and use a compatible PC to reprogram the codes.

I would not recommend this unless you are keeping your working ECU as a backup and you are looking for a way to experiment for less than $100 and you already have a PC (usually a laptop) that is running Windows 7 or older.

Purchasing the an incorrect or malfunctioning VAG cable can keep the product from working properly.

Here's a video on how it works below.

Good shyt CS_AR! I'm the type of person that will loose keys ,it cost me $150+ the first time and a lil over$100 the second i haven't lost them since but i this is a great alternative.

 

i see. yeah i wanted to have 1 ECU as back up, i usually keep may spare parts in the trunk of the car. if i was ever to break down during a road trip or something it could be very handy.

this let me reprogram the keys but, not the ECU?


EDIT: i also have all kinds of laptops, i'm familiar with flashing firmwares and what not.
