2024 Honda CR-V Key Fob Guide (US): Smart Key Options, FCC IDs, Batteries & Costs

The 2024 Honda CR-V sold in the United States typically uses a proximity “Smart Entry” key fob that communicates with the vehicle using an encrypted immobilizer system. That means replacements must match the correct radio/FCC ID and also be authorized to the vehicle—cutting a blade (if present) is only part of the job. Consumers generally find the easiest path is first identifying the exact fob already paired to the car, then choosing between OEM and aftermarket options based on budget and availability. This page summarizes the most common CR-V key fob types, what to check before buying, and typical price ranges in the US as of 2026.

Compatible Key Fob Types

The following key types are typically compatible with the 2024 Honda CR-V. Compatibility varies by trim and options.

Smart Key / Proximity Key Fob (Smart Entry, Push-Button Start)

FCC ID: KR5V2X

This is the most common key type for the 2024 Honda CR-V in the US. The fob transmits a secure RF signal for lock/unlock and communicates with the vehicle’s immobilizer system for push-button start; when the fob is near the vehicle, the CR-V can unlock via the door handle and start without inserting a key.

Features

  • Smart Entry proximity unlock/lock
  • Push-button start authorization (immobilizer-linked)
  • Panic alarm (and remote start on trims equipped with it)

2-4 years typical typical lifespan

Dealer OEM $250-$550 Programming included
Aftermarket $60-$200 Programming separate

Programming

🏢 Dealer Required

Options typically include dealer or automotive-locksmith pairing using secure immobilizer registration. Most 2024 CR-V Smart Keys are not user-programmable; proof of ownership is commonly required for all-key-lost situations.

⚠️ Common Issues

  • Wrong FCC ID or frequency purchased (fob won’t pair or has reduced range)
  • Aftermarket fob supports lock/unlock but not remote start or proximity functions

Smart Key / Proximity Key Fob (alternate FCC ID used on some builds)

FCC ID: KR5V3X

Some 2024 Honda CR-V key fobs in the US appear with an alternate FCC ID depending on production batch and supplier. Functionally it’s the same style of Smart Entry proximity fob, but the correct FCC ID must match your original fob (or the vehicle’s compatible part number) for reliable pairing and button functionality.

Features

  • Smart Entry proximity access
  • Push-button start authorization
  • Trunk/hatch release (when equipped) and panic alarm

🏢 Dealer Required

Programming typically requires secure immobilizer registration tools; consumers generally find verifying the FCC ID on the back of the current fob is the fastest way to avoid compatibility issues.

⚠️ Common Issues

  • Buying a look-alike Honda fob with different FCC ID (buttons may work inconsistently or not at all)
  • Used fobs may be locked to a prior vehicle and may not accept re-registration

đź›’ Buyer's Checklist

Before purchasing a replacement key fob for your 2024 Honda CR-V, verify these points:

1 Verify the FCC ID matches your current key (printed on the back of the fob)
2 Confirm the vehicle is a US-market 2024 CR-V (frequency/standards can differ by country)
3 Check whether your CR-V trim actually has remote start; some fobs list remote-start icons but the vehicle must support the feature
4 Prefer new/virgin fobs for immobilizer registration; used fobs can be difficult or impossible to re-pair
5 If you only have one working key, consider adding a spare before losing the last one (all-keys-lost situations typically cost more)

⚠️ Common Mistakes to Avoid

âś—

Ordering by appearance only instead of matching FCC ID and exact fob type

âś—

Assuming a replacement will be self-programmable (most 2024 CR-V Smart Keys require secure pairing)

âś—

Buying a low-cost aftermarket fob expecting full proximity and remote-start performance without confirming feature support

Frequently Asked Questions

Does the 2024 Honda CR-V key fob use a CR2032 battery?

Yes—most 2024 Honda CR-V Smart Entry proximity fobs in the US use a CR2032 coin-cell battery. If the fob range drops or the car displays a low key battery warning, replacing the CR2032 typically resolves it, but persistent issues can also be caused by fob damage or interference.

Can a 2024 Honda CR-V key fob be programmed at home?

For most US-market 2024 CR-V Smart Keys, home programming is not supported because the key must be securely registered to the immobilizer system. Options typically include dealer or qualified automotive-locksmith equipment for pairing, especially when adding a new Smart Key or replacing a lost one.

How can the correct FCC ID be confirmed for a 2024 CR-V key fob?

The FCC ID is typically printed on the back of the existing fob (or inside the case) and is the most reliable consumer-facing identifier. If no original fob is available, the correct part can often be confirmed using the vehicle’s VIN through official parts catalogs, but the FCC ID on the replacement should still match the compatible listing.

Will a used Honda key fob work on a 2024 Honda CR-V?

Sometimes, but it’s risky. Many used Smart Keys are already registered to another vehicle and may not accept re-registration, and some listings mix incompatible FCC IDs. Consumers generally find new (unregistered) fobs reduce the chance of pairing problems and missing features.

Why does my replacement fob lock/unlock but proximity or remote start doesn’t work?

This commonly happens when the fob is the wrong variant (different FCC ID or internal board), or when an aftermarket fob supports basic buttons but not full proximity/remote-start functions. It can also occur if the vehicle isn’t equipped with remote start or if the fob wasn’t fully registered for all functions during pairing.
