Losing your car keys is a frustrating experience, and when that key is a sophisticated Honda Odyssey Key Fob, the hassle can feel even greater. Like many modern car owners, I discovered this firsthand after misplacing one of my key fobs for our 2019 Honda Odyssey Elite during a family vacation. The realization that a small piece of lost plastic could lead to a surprisingly significant expense and inconvenience was eye-opening.
Replacing a Honda Odyssey key fob isn’t as simple as getting a spare key cut at your local hardware store. It involves not just the remote itself, but also a physical key insert and, crucially, programming to ensure everything works seamlessly with your vehicle. As I navigated the process of getting a replacement, I learned valuable insights into genuine versus aftermarket options, programming complexities, and the costs involved. This guide aims to share that knowledge, helping you understand your options and make informed decisions when facing a Honda Odyssey key fob replacement.
Understanding Your Honda Odyssey Key Fob Needs
Before diving into replacement options, it’s important to understand what exactly comprises your Honda Odyssey key fob system. It’s more than just a remote to lock and unlock your doors. Your key fob typically includes:
- Keyless Entry Remote: This is the electronic component with buttons for locking, unlocking, remote start (depending on your Odyssey trim), and the panic alarm. It communicates wirelessly with your vehicle’s computer.
- Key Insert: A physical key that slides into the remote. This key serves as a backup to manually unlock the doors, especially useful if the remote battery dies or the electronic system malfunctions. It’s also essential for locking/unlocking the glove box.
- Proximity Sensors (for certain trims): Higher trim levels of the Honda Odyssey feature proximity sensors that allow for keyless entry and start. These systems are linked to “Driver 1” and “Driver 2” settings, personalizing vehicle preferences based on which key fob is in use.

Genuine OEM vs. Aftermarket Honda Odyssey Key Fobs: Making the Right Choice
When sourcing a replacement, you’ll encounter two main categories: Genuine OEM (Original Equipment Manufacturer) key fobs and aftermarket options. Understanding the differences is crucial for making the best decision for your needs and budget.
Genuine OEM Honda Odyssey Key Fobs:
-
Pros:
- Guaranteed Compatibility: OEM fobs are made by Honda and specifically designed for your Odyssey model year (2018-2024 for the 5th generation). This ensures seamless integration and functionality.
- Reliability and Quality: OEM parts are typically built to higher quality standards, offering better durability and longer lifespan.
- Dealership Programming: Honda dealerships will readily program genuine OEM fobs.
-
Cons:
- Higher Cost: OEM key fobs are generally more expensive than aftermarket alternatives.
- Dealership Purchase: Often primarily available through Honda dealerships or certified OEM parts retailers.
Aftermarket Honda Odyssey Key Fobs:
-
Pros:
- Lower Price: Aftermarket fobs are usually significantly cheaper than OEM options.
- Wider Availability: Easily found online (e.g., eBay, Amazon) and through locksmiths.
-
Cons:
- Potential Compatibility Issues: Aftermarket fobs may not always be fully compatible with your Honda Odyssey’s system, leading to programming difficulties or limited functionality.
- Questionable Quality: Quality can vary greatly among aftermarket brands. Some may be less durable or reliable.
- Dealership Programming Refusal: Honda dealerships often refuse to program aftermarket key fobs due to potential compatibility and liability concerns.
To identify the correct OEM Honda Odyssey key fob for your vehicle, you can:
-
Check your existing key fob (if you have a spare): Remove the key insert and look for a part number printed in small text inside the remote casing.

Contact a Honda Dealership: Provide them with your vehicle’s VIN (Vehicle Identification Number), and they can look up the correct part number for your specific Honda Odyssey model and trim level.
For 2018-2024 Honda Odysseys, common OEM part numbers include:
| Honda Part # | Remote Notes |
|---|---|
| 72147-THR-A11 | Blank (not programmed for Driver 1 or Driver 2) |
| 72147-THR-A21 | Driver 1 (for trims with proximity functionality) |
| 72147-THR-A31 | Driver 2 (for trims with proximity functionality) |
| Key Insert: 35118-T2A-A50 | Key insert part number for all listed remotes |
Purchasing OEM parts online from reputable Honda parts websites or even used OEM fobs from sources like eBay can be a cost-effective approach, but always verify the part number to ensure compatibility.
Honda Odyssey Key Fob Programming and Key Cutting: Why Professional Help is Needed
Programming a new Honda Odyssey key fob and cutting the key insert are not DIY tasks for most owners. Here’s why:
Key Fob Programming:
- Specialized Equipment: Programming modern key fobs requires diagnostic tools and software that are typically only available to dealerships and specialized locksmiths. These tools communicate with your vehicle’s immobilizer system to register the new key fob.
- No DIY Methods for Recent Models: Online guides suggesting sequences of actions (like turning the ignition on and off repeatedly) for self-programming are generally ineffective for newer Honda Odysseys (2018-2024). These methods might have worked for older models, but not for current generations.
Key Cutting:
- Precision Cutting: The key insert needs to be precisely cut to match your vehicle’s ignition and door lock cylinders. Dealerships and locksmiths have specialized key cutting machines for this purpose.
- Material Matters: Genuine OEM key inserts are typically made of brass, a softer metal that is easier to cut with standard key cutting machines. Aftermarket keys may be made of harder metals like steel, which can damage standard machines. This is a crucial point, as attempting to cut an aftermarket key at a dealership might lead to machine damage or refusal to cut the key.
Key fob programming and key cutting are specialized services typically performed at Honda dealerships or by certified locksmiths.
Where to Get Programming and Key Cutting Services:
- Honda Dealerships: The most reliable option for programming and key cutting. They have the correct tools, OEM parts, and trained technicians. Be prepared to provide proof of ownership (vehicle registration, ID, VIN) to verify you are the rightful owner.
- Certified Automotive Locksmiths: Some locksmiths specialize in automotive key programming and cutting and may offer competitive pricing. Ensure they have experience with Honda vehicles and can program key fobs for recent Odyssey models.
Understanding the Cost of Honda Odyssey Key Fob Replacement
The cost of replacing a Honda Odyssey key fob can vary significantly depending on several factors:
- OEM vs. Aftermarket: OEM fobs and key inserts will be more expensive upfront.
- Dealership vs. Locksmith: Dealerships often have higher labor rates for programming and key cutting compared to locksmiths.
- Location: Prices can vary between dealerships and regions.
Based on quotes I received from Southern California Honda dealerships in early 2024, the price range can be quite broad:
- Dealership 1: $181 (remote and key) + $91 (programming) + $10 (key cutting) = $282 total
- Dealership 2: $130 (remote and key) + $260 (programming and key cutting) = $390 total
Price variations for Honda Odyssey key fob replacement services can be substantial between dealerships, highlighting the importance of shopping around.
Dealerships typically estimate 1.5 to 2 hours for the entire process of programming and key cutting, which contributes to the labor cost.
Recommended Approach to Honda Odyssey Key Fob Replacement
To minimize cost and ensure a successful Honda Odyssey key fob replacement, consider this approach:
- Purchase a Genuine OEM Keyless Entry Remote Online: Source a new or used OEM remote online from a reputable seller. Verify the part number matches your vehicle’s requirements.
- Buy a Genuine OEM Key Insert at the Dealership: Purchase the key insert directly from your local Honda dealership when you schedule your programming and key cutting appointment. This ensures you get a genuine key blank made of the correct material.
- Shop Around for Dealership Programming and Key Cutting: Contact multiple Honda dealerships in your area to get quotes for programming the remote and cutting the key insert. Prices can vary significantly, so compare quotes to find the best deal.
By following these steps, you can potentially achieve a Genuine Honda key fob replacement, programmed and cut by professionals, for a more reasonable price. While locksmiths might offer slightly lower prices, the peace of mind and guaranteed compatibility of dealership service, especially when using a combination of online OEM parts and local dealership services, often makes it the most reliable and ultimately cost-effective solution. Remember to always prioritize genuine parts and professional programming to ensure your Honda Odyssey key fob works flawlessly and keeps you securely on the road.
