Having trouble with your 2017 Nissan Sentra key fob or push-button start? You’re not alone! Key fobs can be tricky, but understanding how to program them can save you time, money, and a lot of frustration. This guide provides a detailed walkthrough of the programming process and addresses common issues.
Understanding Your Nissan Sentra Key Fob
Your 2017 Nissan Sentra key fob is a sophisticated piece of technology that uses radio frequencies to communicate with your car. It allows you to lock and unlock the doors, open the trunk, and even start the engine remotely. The push-button start feature adds another layer of convenience, letting you start your car with the simple press of a button – as long as the key fob is detected inside the vehicle.
Common Key Fob and Push-Button Start Issues
Before we dive into programming, let’s look at some common problems:
- Dead Battery: A dead key fob battery is often the culprit for unresponsiveness. Thankfully, replacing it is a simple process.
- Programming Errors: If you’ve recently replaced your battery or purchased a new key fob, it needs to be programmed to your specific vehicle.
- Key Fob Signal Interference: Electronic devices, metal objects, or even certain environmental factors can interfere with the signal between your key fob and car.
- Mechanical Issues: While less common, issues with the car’s ignition system or the key fob itself may require professional attention.

How to Program a 2017 Nissan Sentra Key Fob
Programming your 2017 Nissan Sentra key fob for push-button start is achievable even for those who aren’t technically inclined. Here’s a step-by-step guide:
What You’ll Need:
- All existing programmed key fobs for your vehicle
- The new key fob you wish to program
Instructions:
- Get Inside Your Car: Close all doors and have all your key fobs ready.
- Insert the First Key Fob: Insert a working key fob into the ignition slot.
- Cycle the Ignition: Turn the ignition to the “ON” position (without starting the engine) and then back to the “OFF” position six times in rapid succession. Your hazard lights will flash to confirm the system is in programming mode.
- Insert the Second Key Fob: Within five seconds, insert the second programmed key fob and turn the ignition to the “ON” position. Your hazard lights will flash again to confirm recognition.
- Program Additional Key Fobs: Repeat step 4 for any other key fobs you wish to program. Remember, you have five seconds between each key fob.
- Exit Programming Mode: Turn the ignition to the “OFF” position. Your hazard lights will flash one last time, signaling you’ve exited programming mode.
Important Note: If the hazard lights don’t flash after completing the cycles, it’s possible you missed a step or took too long between steps. Simply start the process again from the beginning.
Troubleshooting Key Fob Programming
“My hazard lights aren’t flashing after the ignition cycles.”
- Double-check your timing: Ensure you’re turning the key to the “ON” position and back to “OFF” six times within 10 seconds.
- Make sure all doors are closed: Open and close the driver’s side door once to ensure all doors are properly secured.
“I can’t program more than one key fob.”
- Verify the maximum number of programmable keys: Your Sentra might have a limit on the number of programmable key fobs. Consult your owner’s manual for this information.
If you’re still experiencing difficulties, consult a professional automotive locksmith or your Nissan dealership. They have the expertise and tools to diagnose and address more complex issues.
Expert Insight:

Maintaining Your Key Fob and Push-Button Start System
A little maintenance goes a long way:
- Battery Replacement: Replace your key fob battery every 2-3 years or sooner if you notice a decrease in range.
- Avoid Physical Damage: Dropping your key fob can damage its internal components. Use a protective case to minimize impact.
- Keep It Away from Extreme Temperatures: Excessive heat or cold can affect the battery life and overall functionality of your key fob.
