2019 Isuzu NPR Key Fob Programming Guide

Quick reference

Step-by-step on-board programming

Unfortunately, the 2019 Isuzu NPR does not support DIY on-board programming for its key fobs. This means you will not be able to program a new key fob yourself using a sequence of actions like turning the ignition on and off. The vehicle's system requires specialized diagnostic equipment to perform the programming procedure.

Therefore, a professional locksmith or an Isuzu dealership will be required to program any new or replacement key fobs for your 2019 Isuzu NPR.

Battery replacement

Replacing the battery in your 2019 Isuzu NPR key fob is a straightforward process:

1. Locate the small release button or notch on the side or bottom of the key fob. Press the button or use a small flathead screwdriver to gently pry open the key fob casing.
2. Carefully separate the two halves of the key fob. You will see the circuit board and the battery.
3. Note the orientation of the old battery (usually positive side up or indicated with a plus sign).
4. Gently remove the old CR2032 battery. You might need a small, non-metallic tool to carefully pry it out.
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. Test the key fob to ensure it functions correctly.

Where to buy a replacement fob

When considering a replacement key fob for your 2019 Isuzu NPR, you have a few options, each with its own pros and cons:

• Isuzu Dealership: This is the most reliable option for obtaining an original equipment manufacturer (OEM) key fob. Dealerships have direct access to genuine parts and the necessary diagnostic tools for programming. The main downside is the cost, which can be significantly higher than other options. Expect to pay anywhere from $150 to $300 for the fob itself, plus an additional $100 to $200 for programming and key cutting.

• Professional Locksmith: Many automotive locksmiths can provide and program replacement key fobs for a wide range of vehicles, including the 2019 Isuzu NPR. They often have access to aftermarket key fobs that are compatible with your vehicle, which can be a more affordable alternative to OEM. Locksmiths also have the specialized equipment required for programming and key cutting. The cost typically falls between the DIY (if available) and dealership options, generally ranging from $100 to $250 for the fob and programming.

• Online Retailers (e.g., Amazon, eBay): You can often find aftermarket key fobs listed on sites like Amazon or eBay at very attractive prices, sometimes as low as $30-$70. However, there are significant risks involved. You must ensure the key fob is compatible with your specific year and model, and even then, quality can vary. Crucially, even if you purchase a fob online, you will still need a locksmith or dealership to cut the key blade and program the transponder to your vehicle. This means the initial saving on the fob might be offset by programming costs, and you run the risk of purchasing a non-functional or incompatible fob.

If on-board programming isn't supported

As mentioned, the 2019 Isuzu NPR requires professional programming. This is because the key fob contains an immobilizer transponder chip that needs to be electronically paired with your vehicle's engine control unit (ECU). This security feature prevents the vehicle from starting if an unprogrammed or incorrect key is used, deterring theft.

Cost Expectations:

• Locksmith: A mobile locksmith can often come to your location, which adds convenience. The total cost, including the key fob, cutting the blade, and programming the transponder, will likely be in the range of $150 to $350. Always get a quote beforehand.
• Dealership: Dealerships will usually charge a higher labor rate for programming. The total cost for a new fob, cutting, and programming could easily reach $250 to $500 or more.

It's always recommended to call around to a few local locksmiths and your Isuzu dealership to compare pricing and services before making a decision.
