2017 Honda Odyssey — Key Fob Programming Guide

Quick reference

Item	Detail
FCC ID	Varies by trim; read the label on the back of your original remote to confirm (Honda used more than one FCC ID in 2017).
OEM Fob PN	Varies by trim and VIN; verify with dealer/locksmith by VIN or by the part number printed inside the shell.
Aftermarket Options	Remote-head key replacements and full fobs available from reputable brands (e.g., KeylessOption, USARemote). Verify FCC ID/part compatibility before purchase.
Battery Type	Most 2017 Odyssey remote-head keys use CR2032 (verify yours when opening the case).
Programmable On-Board?	No. Both remote functions and the immobilizer must be programmed with a scan tool (Honda HDS or equivalent).
Cuts Required?	Yes. The key blade must be cut to your ignition/doors before programming.

Step-by-step on-board programming

DIY on-board programming is not supported on the 2017 Honda Odyssey. Honda requires registering both the remote transmitter and the immobilizer transponder through the OBD-II port using Honda’s HDS (Honda Diagnostic System) or a professional locksmith tool that supports Honda key/remote registration.

Why no on-board procedure?

• Security: Your Odyssey uses an encrypted immobilizer (ID46/Philips Crypto) that pairs the key’s transponder to the vehicle’s PCM/immobilizer control unit.
• Software access: The vehicle stores key/remote IDs that must be added or erased via a scan tool with the proper software and security access.

What you can do as DIY prep

1. Purchase a compatible remote-head key or fob. Match the FCC ID and button layout to your existing remote or confirm by VIN with a dealer/locksmith.
2. Get the key blade cut. Many locksmiths cut by code (preferred) or by cloning the original key. Some hardware stores can cut, but most cannot program.
3. Schedule programming. A mobile automotive locksmith can come to you, or you can visit a dealer. Bring valid ID, proof of ownership, and all existing keys—unused keys may be erased during programming.

What the pro will do (overview)

1. Connect an HDS/J2534-capable tool to the OBD-II port.
2. Enter security access and register the new key’s immobilizer transponder (ID46) to the car.
3. Register the remote transmitter functions (lock/unlock, power door buttons, panic) to the body control module.
4. Verify that all keys start the engine and that remotes operate every function.

Battery replacement

Most 2017 Odyssey remote-head keys use a CR2032 coin cell.

Steps

1. Remove the small screw on the back (if present). Some shells are snap-together; others have a single Phillips screw.
2. Gently pry the case apart along the seam with a plastic pry tool. Avoid twisting near the circuit board.
3. Lift the rubber keypad and battery holder. Note the battery orientation (typically + side up on Honda remotes—but confirm before removal).
4. Replace with a fresh CR2032. Do not touch the new cell’s faces with bare fingers—use a tissue or gloves.
5. Reassemble and test the buttons. No reprogramming is needed after a battery swap.

Where to buy a replacement fob

• Dealer

  • Pros: VIN-verified part number, guaranteed compatibility, on-site cutting and programming.
  • Cons: Highest cost.
  • Ballpark: $220–$380 for the remote-head key/fob plus $100–$160 for programming and cutting.

• Automotive locksmith (mobile or shop)

  • Pros: Usually lower total cost, mobile service, wide aftermarket/OEM choices, can cut by code and program on-site.
  • Cons: Quality varies—choose a well-reviewed pro and ensure the FCC ID/PN exactly matches.
  • Ballpark: $120–$240 for the fob/key plus $80–$140 for cut/program.

• Online (Amazon/eBay/parts retailers)

  • Pros: Lowest part price if you source the correct FCC ID/PN; convenient.
  • Cons: You still need cutting and programming; counterfeit/incorrect listings are common—match FCC ID, button layout, and frequency; used remotes may be locked to prior vehicles.
  • Ballpark: $25–$80 for an aftermarket remote-head key (uncut, unprogrammed). Cutting ~$25–$50; programming $80–$140.

If on-board programming isn’t supported

Expect to pay for two services: key cutting and electronic programming. Your 2017 Odyssey uses an ID46 (Philips Crypto) immobilizer transponder integrated into the remote-head key. Programming requires a scan tool and security access; there is no insert–cycle–button on-board method.

• Total cost expectations (typical)
  • Dealer: $320–$520 out the door for one complete key/remote.
  • Locksmith: $200–$380 total, depending on part source and travel.
  • DIY part + pro programming: $150–$260 total if you find a compatible fob at a good price.

Tips

• Bring all working keys to the appointment—some procedures erase and re-add every key.
• Verify FCC ID and OEM PN from your original remote or by VIN before purchasing.
• Ask the provider to cut by key code (from VIN) for best fit, especially if your original key is worn.
