2024 Chevrolet Tahoe Key Fob Guide (US): Types, FCC IDs, Batteries & Replacement Options

The 2024 Chevrolet Tahoe typically uses a GM “smart key” (proximity key fob) that supports push-button start and passive entry on most trims. Replacing or adding a Tahoe key fob is more than just buying a remote—compatibility (FCC ID), emergency key blade style, and immobilizer security pairing all matter. Consumers generally find that the fastest way to avoid returns is to match the FCC ID and button layout to an existing working fob. Options typically include OEM, OEM-refurbished, and aftermarket shells/remotes, but programming requirements can vary by equipment and trim.

Compatible Key Fob Types

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

Proximity Smart Key Fob (Push-to-Start / Passive Entry)

FCC ID: Y1Y-4B

This is the most common key type for a 2024 Chevrolet Tahoe equipped with push-button start. The vehicle detects the fob when it’s nearby (passive entry and start), while the buttons handle lock/unlock, remote start (if equipped), and panic. An emergency metal key blade is stored inside the fob for door access if the fob battery is weak.

Features

  • Passive entry (keyless access) and push-button start
  • Remote lock/unlock and panic alarm
  • Remote start on vehicles equipped with remote start

Programming

🏢 Dealer Required

Pairing a new proximity fob typically requires security authorization and a scan tool process; consumers generally find DIY pairing is not supported for adding a new fob on late-model GM full-size SUVs. Some situations (all keys lost vs. adding a spare) can change time and cost.

⚠️ Common Issues

  • Wrong FCC ID or frequency/board revision causing no-start or no-proximity detection
  • Aftermarket housings with poor button feel or reduced range

Proximity Smart Key Fob (Alternate FCC ID / Supplier Variant)

FCC ID: HYQ4AA

Some 2024 Tahoe builds may use an alternate supplier variant of the proximity smart key fob. Functionally it works the same—passive entry and push-button start— but the radio hardware and identifiers can differ, so matching the FCC ID printed on the original fob is critical before buying a replacement.

Features

  • Passive entry and push-button start
  • Lock/unlock, panic, and remote functions
  • Emergency key blade stored inside

🏢 Dealer Required

Programming a new proximity key generally requires immobilizer registration through GM security procedures; options typically include having an automotive locksmith or a dealership perform the pairing depending on equipment availability and authorization.

⚠️ Common Issues

  • Buying a look-alike fob with the same button layout but different FCC ID
  • Used fobs that are locked to a prior vehicle and cannot be re-registered

Typical price ranges are influenced by whether a working key is available, whether the fob is OEM vs. aftermarket, and whether an emergency key blade must be cut. Adding a spare is often less complex than an all-keys-lost situation, which can increase labor time and security steps.

đź›’ Buyer's Checklist

Before purchasing a replacement key fob for your 2024 Chevrolet Tahoe, verify these points:

1 Verify the FCC ID matches your current key (printed on the back or inside the fob)
2 Match the button layout and features (remote start, power liftgate button if present, etc.) to your Tahoe’s equipment
3 Confirm the fob is for a US-market 2024 Tahoe (frequency/region matters even when the shell looks identical)
4 Make sure the emergency key blade type/cut style matches what your vehicle uses (and that a blank/emergency key is included if needed)
5 Avoid “pre-programmed” claims; consumers generally find late-model GM proximity fobs still require vehicle-side security pairing

⚠️ Common Mistakes to Avoid

âś—

Buying by appearance only instead of matching the FCC ID and part number family

âś—

Purchasing a used proximity fob that may be locked to another vehicle or fails security registration

âś—

Assuming a simple battery swap fixes a no-start condition when the issue is actually a damaged fob, desync, or vehicle-side antenna/module fault

Frequently Asked Questions

Does a 2024 Chevrolet Tahoe use a smart key or a traditional key?

Most 2024 Tahoe trims in the US use a proximity smart key fob with push-button start and passive entry. The fob also contains an emergency metal key blade for door access if the fob battery is weak. Some equipment packages can change the button set (for example, remote start or liftgate controls).

Can a 2024 Tahoe key fob be programmed at home?

For late-model GM vehicles like the 2024 Tahoe, consumers generally find that adding a new proximity fob typically requires a security-authorized programming process using professional diagnostic equipment. Some owner actions (like replacing the battery) are DIY-friendly, but registering a new fob to the immobilizer is usually not a DIY procedure.

What battery does a 2024 Chevy Tahoe key fob take?

A 2024 Chevrolet Tahoe proximity key fob commonly uses a CR2032 coin-cell battery. If the fob range drops, the vehicle displays a “key battery low” message, or passive entry becomes inconsistent, a fresh CR2032 from a reputable brand is often the first thing to try.

Will a used key fob work on a 2024 Tahoe?

Sometimes, but it’s risky: many used proximity fobs are already registered to another vehicle and may not accept re-registration. Options typically include buying a new OEM fob, an OEM-refurbished unit with verified reusability, or an aftermarket fob that matches the correct FCC ID and is confirmed compatible with your Tahoe.

How can the correct FCC ID be confirmed for a 2024 Tahoe key fob?

Check the label on the back of the fob, or open the fob carefully to view the internal label if the exterior is worn. The FCC ID must match exactly (for example, Y1Y-4B or HYQ4AA on some builds), because similar-looking GM fobs can use different radio hardware and won’t pair correctly even if the buttons match.
