2020 Isuzu NPR Key Fob Programming Guide

Quick Reference

Step-by-Step On-Board Programming

Unfortunately, the 2020 Isuzu NPR does not support DIY, on-board key fob programming. Programming a new key fob for your Isuzu NPR requires specialized diagnostic equipment, typically referred to as a scan tool, that connects to the vehicle's onboard computer system. This process is complex and often requires accessing security codes and performing specific software routines unique to Isuzu vehicles.

Battery Replacement

Replacing the battery in your 2020 Isuzu NPR key fob is a straightforward process:

1. Locate the small slot or indentation on the side or bottom of the key fob casing. This is where the two halves of the fob meet.
2. Carefully insert a small, flat-head screwdriver or a coin into the slot and gently twist to pry open the key fob casing. It should split into two halves.
3. Inside, you'll see the circuit board and the CR2032 coin-cell battery. Note the orientation of the battery (which side is facing up) before removing it.
4. Carefully pry out the old battery. You may need a small, non-metallic tool to avoid damaging the contacts.
5. Insert the new CR2032 battery with the positive (+) side facing the same direction as the old battery.
6. Align the two halves of the key fob casing and firmly press them back together until they click securely into place.
7. Test the key fob functions (lock, unlock) to ensure it's working correctly.

Where to Buy a Replacement Fob

When considering where to purchase a replacement key fob for your 2020 Isuzu NPR, you have a few options, each with its own advantages and disadvantages:

• Isuzu Dealership:

  • Pros: Guaranteed genuine OEM part, access to the latest programming software, knowledgeable technicians specific to Isuzu.
  • Cons: Typically the most expensive option. Expect to pay between $200-$400 for the fob and programming.

• Automotive Locksmith:

  • Pros: Often more affordable than the dealership, many mobile locksmiths can come to your location, typically stock aftermarket and sometimes OEM fobs, and have the necessary programming tools.
  • Cons: Quality of aftermarket fobs can vary, and not all locksmiths specialize in commercial vehicles like the NPR. Expect to pay between $150-$300 for the fob and programming.

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

  • Pros: Can be the cheapest option for the fob itself.
  • Cons: You're only buying the physical fob, not the programming service. You'll still need to arrange programming with a locksmith or dealership, negating some of the savings. There's a higher risk of receiving a counterfeit or incompatible fob. Prices for the fob alone can range from $30-$100, but remember to factor in professional programming costs.

If On-Board Programming Isn't Supported

Since the 2020 Isuzu NPR requires a scan tool for key fob programming, you will need to rely on a professional service. This means either an Isuzu dealership or an automotive locksmith.

The cost for programming usually includes the labor for using their specialized equipment and expertise. Beyond the basic remote functions, your Isuzu NPR also utilizes an immobilizer transponder system for anti-theft security. This means the key blade itself contains a chip that must be programmed to the vehicle in addition to the remote portion of the fob. This process is also handled by the scan tool and is critical for the vehicle to start.

Expect the total cost (fob + cutting + programming) to range from $150 to $400, depending on your chosen service provider and whether you opt for an OEM or quality aftermarket fob.
