How to Open a Nissan Key Fob

A Nissan key fob allows you to conveniently lock, unlock, and start your car with just a push of a button. However, you may encounter situations where you need to open the key fob itself. Whether you need to replace a dead battery, access the valet key, or perform other tasks, knowing how to open your Nissan key fob is essential. This article provides a step-by-step guide on how to open different types of Nissan key fobs.

Understanding Your Nissan Key Fob

Before attempting to open your key fob, it’s essential to understand the different types available for Nissan vehicles.

  • Traditional Key Fob with Flip Key: This common type features a metal key blade that flips out from the fob’s body.
  • Smart Key Fob: Also known as a keyless entry fob, this type typically doesn’t have a visible key blade.
  • Intelligent Key: Similar to a smart key fob, this advanced type allows you to unlock and start your vehicle without ever taking the fob out of your pocket or purse.

Understanding the type of Nissan key fob you have will help you determine the correct opening method.

Tools You May Need

Depending on the type of Nissan key fob you own, you might need a few basic tools:

  • Small Flat-Head Screwdriver: This tool is helpful for prying open the fob’s casing gently.
  • Fingernail or a Thin Object: You can use your fingernail or a thin object like a credit card to release tabs or catches.

How to Open a Nissan Key Fob with a Flip Key

  1. Locate the Release Button: Look for a small button or switch on the fob’s back or side. This button releases the metal key blade.
  2. Press and Hold the Release Button: While pressing and holding the release button, gently pull out the key blade from the fob’s body. The key blade might be attached to a small hinge.
  3. Identify the Seam: Once the key blade is removed, examine the fob’s edges for a thin seam running around its perimeter. This seam indicates where the two halves of the fob casing connect.
  4. Insert the Screwdriver: Carefully insert the tip of the small flat-head screwdriver into the seam.
  5. Gently Pry Open the Casing: Apply slight pressure to pry open the casing. Avoid using excessive force, as this could damage the fob.
  6. Separate the Halves: Once the casing is partially open, you can use your fingers or a thin object to separate the two halves completely.

Important: Once the fob is open, handle the internal components with care, especially the circuit board and battery.

How to Open a Nissan Smart Key Fob (No Flip Key)

Opening a smart key fob can be trickier because they often have hidden release mechanisms.

  1. Inspect the Key Fob: Look for any notches, grooves, or small holes around the edges of the fob. These might indicate hidden release points.

  2. Check for Emergency Key Access: Some smart key fobs have an emergency key slot. If you find one, insert your fingernail or a thin object into the slot and gently slide or pry open the cover. This cover often hides the physical key blade and sometimes provides access to the battery compartment.

  3. Consult Your Owner’s Manual: If you’re unable to find any obvious release points, refer to your Nissan vehicle owner’s manual. The manual will have specific instructions on opening your particular key fob model.

Replacing the Key Fob Battery

One of the most common reasons for opening a Nissan key fob is to replace the battery.

  1. Open the Key Fob: Follow the instructions above for your specific key fob type.
  2. Locate the Battery: The battery will typically be a small, round, and flat battery (often a CR2032 battery).
  3. Gently Remove and Replace: Carefully remove the old battery. Insert the new battery, ensuring the positive (+) and negative (-) terminals are aligned correctly.

Tip: Avoid touching the battery’s flat surfaces with your fingers, as this can reduce battery life.

Reassembling the Key Fob

To reassemble your Nissan key fob, align the two halves of the casing and press them together firmly until you hear a click. Make sure the casing is properly sealed to prevent water damage.

When to Seek Professional Help

If you encounter any difficulties opening your Nissan key fob or are unsure about any step, it’s best to seek professional assistance from a qualified automotive locksmith or your Nissan dealership. They have the expertise and tools to open your key fob safely and correctly.
