2022-2023 Hyundai Elantra One Smart Key FOB Issue TSB

Certain 2022-2023 Hyundai Elantra, Elantra Hybrid, and Elantra N vehicles were inadvertently delivered to customers with only one complete Smart Key FOB, despite being designed for two. This TSB, 23-01-016H, outlines the necessary steps for dealerships to provide and program the second Smart Key FOB, ensuring owners have both keys as intended. This issue affects the Hyundai Elantra one smart key delivery condition.

Why this matters

Having only one Smart Key FOB can be a significant inconvenience for vehicle owners. It limits access for multiple drivers, poses a problem if the single key is lost or damaged, and can complicate vehicle sharing within a household. This campaign ensures that all affected Hyundai Elantra owners receive the full functionality and convenience they expect from their vehicle.

Symptoms

The primary symptom for owners is simply receiving their new 2022-2023 Hyundai Elantra, Elantra Hybrid, or Elantra N with only one Smart Key FOB and one additional mechanical key, instead of two complete Smart Key FOBs. There are no warning lights or operational faults associated with this specific issue, as the vehicle functions normally with the single provided key.

Important Warnings for Owners

Hyundai has issued several important directives regarding this campaign:

• Dealers must perform this Service Campaign on all affected vehicles prior to customer retail delivery. It must also be completed whenever an affected vehicle is in the shop for any maintenance or repair.
• If a customer has lost their original Smart Key FOB or no longer has access to it, pairing a new Smart Key FOB is still feasible. This requires the technician to have access to the vehicle. The dealer must clearly note this on the Repair Order and add a sticky note to the photo documentation to confirm why only one key is present.
• The key code saving procedure must be performed for both the existing Smart Key FOB and the new Smart Key FOB.
• After a Smart Key FOB has been paired to a vehicle, it cannot be paired to another vehicle.

Part Information

To address the missing second Smart Key FOB, specific part numbers are used depending on the vehicle model and key features:

• Elantra (CN7/CN7a) & Elantra Hybrid (CN7 HEV): FOB-SMART KEY, Part Number 95440-AA000QQH (5 Button plus Remote Start)
• Elantra N (CN7 N): FOB-SMART KEY, Part Number 95440-IB000QQH (5 Button plus Remote Start)
• Elantra N (CN7 N): FOB-SMART KEY, Part Number 95440-IB100QQH (4 Button, no Remote Start)

Repair Procedure Summary

The repair involves a multi-step process for dealers to obtain and program the second Smart Key FOB. This ensures the Hyundai Elantra one smart key issue is fully resolved.

1. Key/PIN Code Identification: Technicians retrieve the vehicle's unique PIN information from the Hyundai Tech Info system. This PIN is crucial for pairing the new key.
2. Smart Key FOB Setup via GDS: The technician connects the Global Diagnostic System (GDS) to the vehicle. With both the existing and new Smart Key FOBs present, and the ignition switch off, they navigate the GDS software.
3. Software Management: Within GDS, they select 'S/W Management', then 'Integrated Body Control Unit - SMK', and finally 'Smart Key Code Saving'.
4. PIN Entry and Pairing: The technician enters the previously retrieved PIN. They then follow on-screen prompts to pair the first Smart Key FOB by pressing the Start Stop Button within five seconds. The GDS will confirm "1st key teaching completed!".
5. Second Key Pairing: The same process is repeated for the second Smart Key FOB. The GDS will confirm "2nd key teaching completed!" and then "Smart key teaching completed!".
6. Verification: After programming, the technician verifies both Smart Key FOBs can arm/disarm the vehicle and allow the engine to start.
7. Documentation: Crucially, the dealer must take Service Technical Update Information (STUI) pictures showing both programmed Smart Key FOBs clearly visible next to the VIN plate on the driver's side door. Claims without these specific photos are subject to debit.

Owner Action

If you own a 2022-2023 Hyundai Elantra, Elantra Hybrid, or Elantra N and only received one Smart Key FOB, you should contact your authorized Hyundai dealer. The campaign is performed free of charge. Dealers are instructed to complete this service on all affected vehicles before retail delivery and whenever an affected vehicle is in for other maintenance or repair. This ensures that the Hyundai Elantra one smart key problem is resolved for all eligible vehicles.
