Nissan & Infiniti Transponder Keys

Shop Nissan and Infiniti transponder keys designed for automotive locksmiths, key programmers, and other security professionals. Noble Key Supply carries dependable aftermarket transponder keys for select Nissan and Infiniti vehicles, with several chip technologies and key profiles available.

Browse the collection to find replacement keys with ID46, 4A, 4D60, Philips 41, and Texas Instruments 4C transponder chips. Always compare the chip type, keyway, blade profile, vehicle application, and programming requirements before ordering.

Nissan Transponder Keys

Our Nissan transponder-key selection includes options for select cars, trucks, SUVs, and vans. Available key styles include NI02-PT, NI04-PT, NI07-PT, and NSN11T2-PT aftermarket keys.

Depending on the application, these keys may work with vehicles from model lines such as the Nissan Altima, Maxima, Sentra, Versa, Frontier, Pathfinder, and Xterra. Compatibility varies by model year, trim, ignition system, and region, so technicians should verify the complete application rather than relying on the vehicle model alone.

Infiniti Transponder Keys

Find aftermarket transponder keys for select Infiniti vehicles equipped with traditional keyed-ignition systems. The collection includes the INF45-PT key with a Texas Instruments 4C OEM chip for compatible applications.

Infiniti vehicles may use different key systems across model years and trims. Confirm the original key’s blade, transponder technology, FCC or part information when available, and vehicle programming procedure before selecting a replacement.

Multiple Transponder-Chip Technologies

Nissan and Infiniti vehicles have used several immobilizer technologies. This collection includes keys featuring:

• ID46 transponder chips
• 4A transponder chips
• 4D60 transponder chips
• Philips 41 OEM chips
• Texas Instruments 4C OEM chips

The transponder must be compatible with the vehicle’s immobilizer system. A key may have the correct blade profile but still fail to start the vehicle if its chip type or programming protocol is incorrect.

Nissan and Infiniti Keyways

Available products use common Nissan and Infiniti blade profiles, including keys associated with NSN14 and NSN11 applications. Product listings may also reference test keys such as DA34, DA25 (X123), and DA31 (X210) to help locksmiths identify the correct profile.

Matching the keyway is essential for accurate cutting and smooth mechanical operation. Compare the original key with the product photographs and technical details before cutting a replacement.

Insert and Emergency Key Blades

The collection also includes an insert or emergency-key option for select applications. These blades are mechanically cut and may be used with compatible remote or proximity-key assemblies.

An emergency blade does not replace the electronic functions of a transponder key, remote, or smart key. Verify whether the application requires a standalone transponder key, an insert blade, or a complete electronic key assembly.

Check Compatibility Before Ordering

Before purchasing a Nissan or Infiniti transponder key, confirm:

• Vehicle year, make, model, and trim
• Original key blade and keyway
• Required transponder-chip type
• Ignition or immobilizer system
• Relevant OEM, aftermarket, or FCC identifiers
• Supported programming method
• Whether an insert blade or complete transponder key is needed

Using multiple identifiers helps reduce application errors, especially when different immobilizer systems were used during the same model year.

Cutting and Programming Requirements

Most transponder keys require both mechanical cutting and electronic programming. The blade must be cut to operate the vehicle’s locks and ignition, while the embedded chip must be registered with the immobilizer system before the key can start the engine.

Programming procedures vary by vehicle. Some applications may support onboard programming, while others require compatible diagnostic or automotive-key programming equipment. Certain procedures may also require an existing working key, a security PIN, or access to vehicle-specific immobilizer information.
