Lost your Nissan 370z key fob or need to program a new one? Don’t worry, you might be able to do it yourself at home. While issues can sometimes stem from a dead 370z Key Fob Battery, often reprogramming is the solution when your key fob becomes unresponsive. This guide provides a straightforward, step-by-step process to program your Nissan 370z key fob, getting you back on the road quickly.
Step-by-Step Guide to Programming Your 370z Key Fob
Before you begin, ensure you have all your key fobs present, as this process will reprogram all of them. Also, while a low 370z key fob battery can cause issues, this programming procedure is different from a battery replacement. If you suspect a dead battery, replacing it might be a simpler first step, but if reprogramming is needed, follow these instructions carefully:
-
Unlock the Doors: Make sure your Nissan 370z is completely unlocked. You can do this using a functioning key fob or manually unlocking both the driver and passenger doors. Double-check that both doors are unlocked before proceeding.
-
Ignition Cycling Sequence: This is the core of the programming process. Insert your key into the ignition. You need to perform a specific sequence of turning the ignition between the LOCK and ON positions. Do this rapidly, six times within a ten-second window. Crucially, end this sequence with the ignition in the OFF position.
-
Observe for Indicator Flashes: Leave the key in the ignition in the OFF position. If you’ve successfully entered registration mode, your car’s indicators will flash twice. This is your confirmation. If the indicators don’t flash, you’ll need to start the process again from step one. Common reasons for failure include not unlocking both doors or not completing the ignition cycling quickly enough. Don’t be discouraged if it doesn’t work on the first try; persistence is key!
-
Key Fob Programming: Once you see the two indicator flashes, you are in registration mode. Now, take your first key fob. Press and HOLD the UNLOCK button. While still holding the UNLOCK button, press and RELEASE the LOCK button three times. Only after pressing the lock button three times, release the UNLOCK button.
-
Confirmation Flash: After performing the button sequence on the key fob, you should see a single flash of the indicators. This single flash confirms that the key fob has been successfully programmed. If you miss the flash, simply repeat the “press and hold unlock, press lock three times, release unlock” sequence – you don’t need to restart the entire process from the beginning.
-
Programming Additional Key Fobs (Optional): If you have another key fob to program, do NOT remove the programmed key from the ignition or turn the ignition ON. Immediately insert the next key fob you want to program into the ignition (without turning it on). Then, repeat the “press and hold unlock, press lock three times, release unlock” sequence for this second key fob. Again, look for the single indicator flash to confirm successful programming. Repeat this for any additional key fobs.
-
Final Confirmation: After programming all your key fobs, turn the ignition ON with the last key fob you programmed. If everything has been successful, you will see two final indicator flashes. This confirms that the programming process is complete and all your key fobs should now be working.
-
Testing Your Key Fobs: Remove the key from the ignition and test all your programmed key fobs to ensure they lock and unlock the doors correctly. If any key fobs are not working, you may need to repeat the entire process from the beginning.
Troubleshooting and Key Fob Battery Considerations
If you encounter issues during programming, double-check each step and ensure you are following the instructions precisely. A common issue, unrelated to programming but worth considering, is the 370z key fob battery. If your key fob is still unresponsive after programming, or if it has very limited range, replacing the 370z key fob battery might be necessary. These batteries are typically CR2032 button cells and are relatively easy and inexpensive to replace. Refer to your owner’s manual for instructions on 370z key fob battery replacement.
By following these steps, you should be able to successfully program your Nissan 370z key fob. Remember to be patient and persistent, and always double-check each step for accuracy.
