2020 Nissan Titan Key Fob Programming Guide

Quick reference

Step-by-step on-board programming

The 2020 Nissan Titan utilizes a sophisticated smart key system that unfortunately does not support DIY on-board programming. The vehicle's immobilizer system and smart key module require specialized diagnostic equipment to program new key fobs. This means you won't be able to program a new fob yourself using a series of button presses or key turns.

Battery replacement

1. Locate the small release button or switch on the side of the key fob. Press or slide it to release the emergency key blade. Pull the emergency key blade out.
2. With the emergency key blade removed, you'll see a small slot or notch in the key fob casing. Use a small flathead screwdriver or a coin to carefully pry open the two halves of the fob.
3. Gently separate the two halves. Be careful not to damage the internal electronics.
4. Locate the CR2032 coin cell battery. Note its orientation (which side is up).
5. Carefully remove the old battery. You may need to use a small non-metallic tool to gently pry it out.
6. Insert the new CR2032 battery, ensuring it's oriented correctly (positive (+) side usually facing up).
7. Align the two halves of the key fob and press them firmly together until they click securely into place.
8. Reinsert the emergency key blade.

Where to buy a replacement fob

• Nissan Dealership: While often the most expensive option (typically $250-$400 for the fob and programming), a dealership guarantees you an OEM part and proper programming. They will also cut the emergency key blade for you.
• Automotive Locksmith: Locksmiths specializing in automotive keys are usually a more cost-effective solution than a dealership (often $150-$300 for fob and programming). They have the necessary diagnostic tools and can typically program both OEM and high-quality aftermarket fobs. They can also cut the emergency key blade.
• Online Retailers (e.g., Amazon, eBay): You can often find replacement key fobs (both OEM and aftermarket) for significantly less online (e.g., $30-$100 for just the fob). However, remember that you'll still need to pay a locksmith or dealership to program it and cut the emergency key blade. Be cautious about the quality of aftermarket fobs; ensure they specify compatibility with your 2020 Nissan Titan and have the correct FCC ID (CWTWB1G767).

If on-board programming isn't supported

As mentioned, the 2020 Nissan Titan requires specialist equipment for key fob programming due to its advanced immobilizer system. New key fobs must be programmed to the vehicle's immobilizer to allow the car to start. This often involves connecting a diagnostic scan tool to the vehicle's OBD-II port, which communicates with the Body Control Module (BCM) and the Intelligent Key Control Unit to register the new key.

Cost Expectations:

• Programming Only: If you purchase a fob online, expect to pay a locksmith or dealer anywhere from $80-$150 for programming and cutting the emergency key blade.
• Fob + Programming: As noted above, expect $150-$300 from a reputable locksmith or $250-$400 from a Nissan dealership.

The key fob for your 2020 Nissan Titan also contains a transponder chip (part of the immobilizer system). This chip needs to be correctly programmed to the vehicle to allow it to start. Without proper programming, even if the remote functions work, the car will not recognize the key and will not start.
