With all the new part numbers coming out for keys it’s definitely hard to keep up as a locksmith and a supplier. There always seems to be some sort of overlap and cross compatibility. We rely on a lot of you for feedback from the field when discoveries are made and for testing. Over the past couple years, Nissan has released a new system that caused some keys proximity to not function. Even though the keys have the same FCC ID, continental number and interchange number; the keys are not interchangeable.
Today, we are talking specifically about the Nissan Rogue smart key with the part number of 6RR7A. This key was limited to function on 2018-2020 Rogues because the 2021 switched to the new system requiring a 6TA7B. When programming a 6RR7A smart key on the new system, proximity function would not work causing you to have to hold the key to the start button to start the vehicle.
We found that the circuit boards in keys with the older part number could indeed be flashed with the newer part number. This allows us to use this key now on the new system (2021-2024). A recent video provided by an amazing customer of ours shows the old part number key functioning perfectly on a 2024 Rogue.
The part number of Nissan smart keys can be located when removing the emergency blade and looking in the bottom right hand corner. 
We will be flashing our old part number 6RR7A Rogue keys with the new 6TA7B system files so that they can be used from 2021-2024 to be sold as a 6TA7B. The 6RR7A key listing will currently remain as the 2018-2020 Rogue. The 6TA7B listing will be a 6RR7A key or a 6TA7B original part number key but will flashed for the new system 21+. The fitment will be updated to reflect (2018-2024) Rogue.
This results in three great things:
- Consistent stock will be available to you as the 6TA7B keys are harder to get on the used key market.
- Overall lower cost of key to you because we can procure the old part number more readily.
- Less SKU’s for you to stock in your inventory since one can cover more!
