2017 Nissan Altima Key Fob Programming

Quick reference

Step-by-step on-board programming

Unfortunately, the 2017 Nissan Altima does not have a user-programmable on-board procedure for key fobs. This means you cannot program a new key fob yourself using a series of button presses or ignition cycles. The vehicle's immobilizer system, which is designed to prevent theft, requires specialized diagnostic equipment to marry new key fobs to the car's computer.

To program a new key fob for your 2017 Nissan Altima, you will need to take it to a qualified locksmith or a Nissan dealership. They possess the necessary tools and software to perform this procedure correctly and ensure proper communication between the fob and your vehicle.

Battery replacement

Replacing the battery in your 2017 Nissan Altima key fob is a straightforward process:

1. Locate the small release button or switch on the side of the key fob. Press or slide it to release the integrated emergency key blade. Pull the key blade out.
2. With the emergency key removed, you will see a small slot or notch. Use a flat-head screwdriver or a coin to carefully pry open the two halves of the key fob casing.
3. Gently separate the two halves to reveal the circuit board and the battery.
4. Note the orientation of the old battery (CR2032), usually positive (+) side facing up. Carefully pry out the old battery.
5. Insert the new CR2032 battery with the positive (+) side facing the same direction as the old one.
6. Align the two halves of the key fob casing and press them firmly together until they click securely into place.
7. Reinsert the emergency key blade into its slot.

Where to buy a replacement fob

When considering where to purchase a replacement key fob for your 2017 Nissan Altima, you have a few options, each with its own pros and cons:

• Nissan Dealership:

  • Pros: Guaranteed genuine OEM part, expert programming services. They can also cut the integrated key blade precisely.
  • Cons: Most expensive option. Expect to pay anywhere from $250 to $400+ for the fob and programming.

• Automotive Locksmith:

  • Pros: Often more affordable than the dealership, can provide and program OEM or high-quality aftermarket fobs, and can cut the integrated key blade. Many locksmiths offer mobile services, coming to your location.
  • Cons: Quality of aftermarket fobs can vary, so ensure your locksmith uses reputable brands. Pricing for the fob and programming generally ranges from $150 to $300, depending on the fob type and service.

• Online Retailers (e.g., Amazon, eBay):

  • Pros: Potentially the cheapest option for the key fob itself. You can find both OEM and aftermarket options.
  • Cons: You still need to pay a locksmith or dealer for programming and key cutting. There's a risk of receiving a non-compatible or low-quality fob from less reputable sellers. Beware! If the FCC ID (CWTWB1U815) doesn't match, it likely won't work. Expect to pay $30-$80 for the fob online, plus programming and cutting fees from a third party (which can add another $100-$200).

If on-board programming isn't supported

As mentioned, the 2017 Nissan Altima requires specialist tools for key fob programming. This is due to the advanced immobilizer system, which uses a transponder chip embedded in the key fob to communicate with the vehicle's engine control unit (ECU). Without this proper communication, the car will not start, even if the key blade fits the ignition.

When contacting a locksmith or dealership, be prepared for the following costs:

• Fob Cost: This varies significantly based on whether you choose an OEM or aftermarket option. (Refer to "Where to buy" section for price ranges).
• Programming Fee: Locksmiths typically charge $75 - $150 for programming, while dealerships might charge a flat diagnostic fee (often an hour of labor) which can be $100 - $200+.
• Key Cutting: If your new fob has an integrated emergency key blade (which most do for the Altima), it will need to be cut to match your original key. This is usually included in the programming cost or a small additional fee (around $20 - $50).

Factor in these separate costs if you purchase a fob online, as the initial low price might be misleading once programming and cutting are added.
