Honda Key Fob Compatibility: Are Fobs Interchangeable?
Some Honda models share remote parts, but not every fob swaps. Check cross-model fitment, full part numbers, equipment and programming before buying.
Some Honda models share keyless-entry parts, but there is no universal Honda key fob. Compatibility belongs to the exact part and vehicle configuration—not simply the Honda badge, model name or remote shape. A shared remote module also does not establish that the complete key, blade and immobilizer components are interchangeable.
The examples below use U.S.-market parts catalogs. For an imported Honda, have the supplier check its original market as well as its VIN.
Where cross-model compatibility is documented
A useful example is Honda 72147-SWA-A01, cataloged as a Module Assembly, Keyless. HondaPartsNow lists it for these applications:
| Model | Cataloged model years |
|---|---|
| CR-V | 2007–2011 |
| Fit | 2009–2013 |
| Insight | 2010–2014 |
| CR-Z | 2011–2015 |
These are application ranges, not a guarantee for every trim or market. The HondaPartsNow listing identifies these ranges, and a second parts catalog identifies the same module for CR-V, Fit, Insight and CR-Z.
The important limit: this is a shared transmitter module, not proof that the whole key swaps. The catalog separately lists the immobilizer key, combined immobilizer/transmitter key and case components. If you are buying a complete replacement rather than just the module, confirm the complete assembly for your vehicle.
That is how to interpret a listing that names several Honda models: it may describe legitimate shared hardware, but you still need the exact application and the correct scope of the part.
Why matching appearance or FCC ID is not enough
Two Honda remotes can share an FCC ID while having different part numbers and functions. For example:
- A retailer lists 72147-TG7-A31 / 72147-TLA-A11 for a 2017 CR-V as a five-button smart remote with FCC ID KR5V2X, variant V44. Its buttons include hatch control and remote start. CR-V remote specifications
- Another retailer lists 72147-THR-A21 for a 2018–2020 Odyssey as a seven-button smart remote with FCC ID KR5V2X, variant V41, including separate left and right sliding-door controls. Odyssey remote specifications
The shared FCC ID alone does not establish interchangeability. Match the full Honda part number, any variant marking and the supported functions, then obtain vehicle-specific confirmation.
Configuration also matters within one model. A dealer catalog describes CR-V 72147-3A0-A01 as a Driver 1 fob and references power-liftgate equipment; another lists 72147-3A0-A11 as Driver 2. Do not assume the final characters are unimportant or that any fob labeled “CR-V” is equivalent. Driver 1 listing · Driver 2 listing
Confirm a replacement before buying
Send the supplier or programmer:
- Your VIN, model year and original sales market. Include trim and whether the vehicle uses an ignition key or push-button start.
- Photos of the existing remote and its markings. Record the complete part number, FCC ID and any variant code on the back or inside the battery cover.
- The functions you need. Include remote start, trunk or power-tailgate control, sliding doors and any Driver 1/Driver 2 designation.
- The proposed replacement’s exact listing and condition. Ask the programmer to approve a new, used, refurbished or aftermarket unit before you purchase it.
If the seller offers a different part number, request confirmation that it is an approved replacement or interchange for your VIN—not merely a similar-looking remote. If all keys are lost, use VIN-based identification rather than guessing from photographs.
Compatible does not mean ready to use
Keep three jobs separate: remote locking, authorization to start, and mechanical emergency entry. A shared transmitter listing does not, by itself, settle all three.
For the CR-V smart remote and Odyssey smart remote cited above, the retailers specify dealer or automotive-locksmith programming and emergency-blade cutting. The CR-V listing explains that the metal blade opens the door if the remote battery dies. Matching hardware is therefore only the first step, not a reason to try a generic Honda ignition-cycling procedure.
Before paying, get two confirmations: the supplier verifies fitment, and the programmer agrees to program that exact unit. For the rest of a model-specific replacement job, see our Honda CR-V replacement guide or Honda Pilot replacement guide.
