2024 Hyundai Palisade Key Fob Guide (US): Types, Batteries, Programming & Costs

The 2024 Hyundai Palisade (US) typically uses a proximity “smart key” fob for push-button start, with trims varying by features like remote start and power liftgate. Replacement costs can vary widely depending on whether you buy OEM or aftermarket and who programs it. Most owners need professional programming for a new fob, and used fobs are frequently a poor bet because they may be locked to another vehicle. Knowing your exact fob version, emergency key style, and battery type helps avoid returns and programming failures.

3 Key Types

$60-$220 Aftermarket Range

Compatible Key Fob Types

The following key types are typically compatible with the 2024 Hyundai Palisade. Compatibility varies by trim and options.

Proximity Smart Key (Push-Button Start) – Standard Smart Key

A proximity (keyless entry) smart key fob that communicates with the Palisade to allow lock/unlock and push-button start when the fob is nearby. It also contains (or is paired with) an emergency mechanical key blade used if the fob battery is dead.

Features

  • Proximity keyless entry (touch/handle unlock when nearby, if equipped)
  • Push-button start authorization
  • Alarm/panic function

Programming

🏢 Dealer Required

New smart keys typically must be registered to the vehicle with factory-level diagnostic equipment (dealer or an automotive locksmith with appropriate tools). If all keys are lost, programming is usually more involved and may require proof of ownership and, in some cases, additional steps to restore immobilizer registration. Consumers generally find that used smart keys are often not reusable if they are already locked/registered to another vehicle.

⚠️ Common Issues

  • Dead/weak CR2032 battery causing intermittent detection or no-start
  • Aftermarket fob purchased with the wrong frequency/part number for the vehicle
  • Used fob cannot be programmed because it is already paired to another Palisade

Proximity Smart Key with Remote Start & Power Liftgate

A proximity smart key variant that typically adds dedicated buttons for remote engine start and power liftgate control (common on higher trims/packages). Function availability can depend on vehicle equipment and regional configuration.

Features

  • Remote start (when equipped and enabled)
  • Power liftgate open/close (when equipped)
  • Proximity keyless entry and push-button start

Programming

🏢 Dealer Required

Programming typically requires registering the fob to the vehicle’s immobilizer/BCM system. Remote start and liftgate functions generally work only if the vehicle is equipped and the correct fob variant is used. If replacing just the fob shell, the internal board and emergency key blade (or insert) usually must be transferred carefully to avoid damage.

⚠️ Common Issues

  • Liftgate button present on the fob but vehicle not equipped (feature won’t function)
  • Remote start range complaints due to low battery or RF interference
  • Incorrect emergency key insert style leading to a fob that won’t close properly

Digital Key (Phone-as-Key) – Feature/Option on Some Trims

A smartphone-based key function (where supported) that can allow locking/unlocking and starting the vehicle using a compatible phone and Hyundai’s ecosystem. This is not a traditional RF fob and does not use an FCC ID like a standard transmitter.

Features

  • Phone-based lock/unlock (feature availability varies by trim and device)
  • Phone-based start authorization (feature availability varies)
  • Ability to keep a traditional fob as a backup

🏢 Dealer Required

Setup typically requires at least one working smart key and a compatible smartphone. Availability depends on trim level, model-year equipment, and phone OS/device support. Consumers generally find it useful as a convenience/backup, but not a complete substitute if the phone is lost, dead, or unsupported.

⚠️ Common Issues

  • Incompatible phone or OS version
  • Account/login or app provisioning problems
  • Phone battery dead or NFC/Bluetooth disabled preventing entry/start

Pricing varies by region, trim (remote start/liftgate fobs can cost more), and whether you still have a working key. All-keys-lost scenarios typically cost more due to added labor, towing/lockout considerations, and immobilizer registration steps. Aftermarket fobs may reduce parts cost, but consumers generally find compatibility and return policies matter as much as price.

🛒 Buyer's Checklist

Before purchasing a replacement key fob for your 2024 Hyundai Palisade, verify these points:

1 Match the fob to your exact trim/features (remote start and liftgate buttons must align with vehicle equipment).
2 Confirm the correct OEM part number and frequency for a 2024 US-market Palisade before purchasing; listings that only say “fits Palisade” are risky.
3 Avoid used/refurbished smart keys unless the seller explicitly guarantees the fob is new/unlocked and returnable if it won’t program.
4 Verify what is included: fob, emergency key insert/blade, and whether cutting is needed for the mechanical key.
5 Ask upfront about programming capability and total out-the-door cost (fob + cutting + programming), especially for all-keys-lost situations.

⚠️ Common Mistakes to Avoid

✗

Buying a fob based on appearance only (same shell can hide incompatible electronics).

✗

Assuming a used smart key can always be reprogrammed to another vehicle.

✗

Replacing the fob battery but installing it upside down or bending the contacts, creating intermittent operation.

Frequently Asked Questions

What battery does a 2024 Hyundai Palisade key fob use?

Most 2024 Palisade smart key fobs typically use a CR2032 coin-cell battery. If your fob behaves inconsistently after replacement, check battery orientation and that the contacts are not bent.

Can I program a new Palisade smart key myself?

In most cases, adding or replacing a proximity smart key requires professional programming with factory-level tools (dealer or an automotive locksmith with compatible equipment). DIY on-board programming is generally not available for modern Hyundai proximity keys.

Should I buy a used key fob for a 2024 Palisade?

Consumers generally find used proximity smart keys are risky because many are already registered to another vehicle and may not be reusable. If you consider used, prioritize a strong return policy and written confirmation that the fob is new/unlocked and compatible with your exact vehicle.
