2016 Isuzu NQR — Key Fob Programming Guide

Quick reference

Step-by-step on-board programming

Most 2016 Isuzu NQR trucks do not support a DIY, on-board remote programming sequence (there’s no ignition on/off or door cycling method). Transmitter registration is performed through the truck’s Body Control Module (BCM) or keyless entry module with a dealer-level scan tool (Isuzu Tech2/MDI) or a capable locksmith programmer. This is by design to prevent unauthorized pairing on commercial vehicles and because many NQRs use accessory keyless systems that only enter learn mode via scan tool or a hidden programming switch.

If you have a factory or dealer-installed RKE system and a compatible scan tool, the typical high-level process is:

1. Verify the truck actually has power door locks/RKE: look for a lock/unlock switch on the dash or driver door and confirm there’s a keyless module behind the dash. If the truck lacks these, install an add-on keyless kit instead of trying to program a fob.
2. Connect the scan tool: hook up to the OBD-II port under the driver side of the dash and establish communication with the BCM or Keyless Entry module.
3. Enter Remote/Transmitter Programming: in the tool’s menu, select Body > Keyless Entry/BCM > Program Transmitters (wording varies by tool).
4. Add or replace remotes: follow on-screen prompts. You’ll be asked to press Lock/Unlock on each remote in sequence to learn them. Most systems erase all previously learned fobs when you start this routine, so have all remotes present.
5. Save and test: exit programming, cycle ignition off, then test Lock/Unlock at the driver door and from 10–20 feet away.

If your truck uses an accessory RKE with a discrete programming button (rare), the steps are usually:

1. Turn ignition ON (engine off).
2. Press and hold the small programming/learn button on the RKE module until the locks cycle or the LED flashes.
3. Within 10 seconds, press Lock on the first remote; wait for a confirmation cycle, then program any additional remotes the same way.
4. Turn ignition OFF to exit learn mode and test operation.

Note: Module locations vary; many are mounted behind the lower dash panel on the driver side.

Battery replacement

Because multiple remote styles were used on NQR trucks, open yours to confirm battery type before buying.

1. Identify seam and screw: some remotes have a small Phillips screw; others are snap-fit with a slot at the key ring end.
2. Open the shell: remove the screw (if present) and pry at the notch with a plastic tool. Work gently to avoid cracking the shell.
3. Note polarity: most coin cells install with the + side facing you. Take a photo before removal.
4. Replace the coin cell: CR2032 is most common; some accessory remotes use CR2016/CR2025. Match what you removed.
5. Clean and reassemble: wipe contacts if corroded, re-snap/replace screw, and test range. No re-programming is required after a battery change.

Where to buy a replacement fob

• Dealer (Isuzu):
  • Pros: Confirms correct transmitter by VIN; has the proper tool to program.
  • Cons: Highest price. Expect $140–250 for the remote/transmitter, plus $80–150 for programming.
• Automotive locksmith:
  • Pros: Mobile service; lower total cost; can source compatible OEM or high-quality aftermarket remotes or install an add-on keyless kit if your truck didn’t come with RKE.
  • Cons: Availability varies by region; will still need access to the truck for programming.
  • Typical cost: $80–160 for the remote, $75–125 to program; add-on keyless kits (parts + install) typically $180–350.
• Online (Amazon/eBay):
  • Pros: Lowest part cost if you know the exact FCC ID and part number printed on your current remote.
  • Cons: Risk of wrong part or used/locked transmitters; you’ll still pay a pro to program. Expect $20–80 for the transmitter only.

If on-board programming isn’t supported

• Expect a scan-tool session: Most 2016 NQRs require Tech2/MDI or an advanced aftermarket programmer to add/erase remotes. Programming labor is typically 0.5–1.0 hour.
• Immobilizer/transponder notes: Many North American NQR builds use a plain mechanical key (no chip). Some fleets spec an immobilizer; if so, a transponder key must also be programmed with a scan tool. The exact transponder type varies by build—verify with the VIN or have a locksmith test your key with a chip reader. Signs of a chip system include a “Security” light on the cluster and a thicker plastic key head.
• All keys lost: If your truck has an immobilizer and all keys are lost, budget additional time for security access and key coding. Costs often run $180–350 at a locksmith, more at a dealer.
• No factory RKE installed: If your NQR lacks power locks/keyless, consider a quality add-on keyless entry kit. It provides remote lock/unlock (and can control an alarm) without replacing the ignition key.

Have your current remote in hand when ordering—its label is the definitive source for the FCC ID and part number. A photo of that label plus your VIN will save time and ensure you get a fob that can be programmed to your specific truck.
