Understanding Your 2017 Nissan Maxima Key Fob
The 2017 Nissan Maxima comes equipped with a sophisticated keyless entry remote, often referred to as a smart key fob. This isn’t just a simple remote; it’s a crucial component of your vehicle’s convenience and security system. This key fob allows for:
- Remote Engine Start: Start your Maxima from a distance, perfect for pre-heating or cooling the cabin.
- Keyless Entry: Unlock and lock your doors with the push of a button.
- Trunk Release: Conveniently open the trunk remotely.
- Panic Alarm: Activate the car alarm in emergency situations.
- Push-Button Start: Start your vehicle’s engine with the key fob inside the car, thanks to the push-to-start ignition system.

These features are powered by a small battery inside the key fob. When this battery weakens, the functionality of your key fob can become unreliable.
Identifying the Correct Battery for Your 2017 Maxima Key Fob
The battery powering your 2017 Nissan Maxima key fob is a CR2032 battery. This is a common 3V lithium coin cell battery, widely available at most drugstores, supermarkets, and online retailers. It’s important to use the correct battery type to ensure proper function and longevity of your key fob.
Using the wrong battery type could lead to:
- Reduced Range: The key fob may not transmit signals effectively from a distance.
- Intermittent Operation: Buttons may become unresponsive or work only sporadically.
- Key Fob Failure: In severe cases, incorrect batteries could potentially damage the key fob’s electronics.
Always double-check that you are purchasing a CR2032 battery for your 2017 Nissan Maxima key fob replacement.
Replacing Your 2017 Nissan Maxima Key Fob Battery: A Simple Process
While specific instructions may vary slightly depending on the exact design of your key fob, the general process for replacing the battery in your 2017 Nissan Maxima key fob is usually quite simple. You will typically need a small flathead screwdriver or a similar tool to gently pry open the key fob casing.
General Steps (Always refer to your owner’s manual for specific instructions):
- Locate the Notch: Look for a small notch or seam on the key fob casing. This is usually where you can insert a tool to open it.
- Carefully Pry Open the Casing: Use a small flathead screwdriver or a similar tool to gently pry open the key fob casing at the notch. Be careful not to use excessive force, as you could damage the plastic.
- Identify the Battery: Once open, you’ll see the CR2032 battery. Note the orientation of the battery (+ side up or down) before removing it.
- Remove the Old Battery: Gently pry out the old CR2032 battery.
- Insert the New Battery: Install the new CR2032 battery, ensuring it’s placed in the correct orientation (matching the polarity of the old battery).
- Close the Key Fob Casing: Carefully snap the key fob casing back together until it’s securely closed.
After replacing the battery, test all the buttons on your key fob to ensure they are working correctly.
When to Consider a Full Key Fob Replacement
While a battery replacement often resolves issues with a weak key fob, there are situations where you might need to consider a complete key fob replacement for your 2017 Nissan Maxima. These situations include:
- Damaged Key Fob: If your key fob is physically damaged – cracked casing, broken buttons, or water damage – a new battery may not fix the underlying issues.
- Lost or Stolen Key Fob: If you’ve lost your key fob or it has been stolen, replacement is necessary for security reasons.
- Persistent Key Fob Issues: If you’ve replaced the battery and are still experiencing problems like reduced range or intermittent operation, there might be an issue with the key fob’s internal electronics.
In these cases, purchasing a new 2017 Nissan Maxima key fob and having it professionally programmed is the best course of action.

Programming Options:
- Nissan Dealership: Your local Nissan dealership can program a new key fob for you. This is often the most convenient option, but it can also be the most expensive.
