2017-2024 Pacifica & Voyager Key Fob Not Detected: Programming, Costs, and Replacement
This guide covers the common causes of key fob failure for the Chrysler Pacifica and Voyager, and explains the critical programming requirements for all replacements.
- This key fob MUST be professionally programmed by a dealer or automotive locksmith; DIY programming is not possible.
- The most common problem, "Key Fob Not Detected," is usually caused by a dead CR2032 battery and can be bypassed by pushing the start button with the fob itself.
- When buying a used fob, you MUST match the FCC ID (M3N-97395900) and be aware that it may need to be professionally unlocked before it can be programmed.
- A used OEM fob is often a more reliable choice than a new aftermarket one, but requires extra steps like getting a new emergency key blade cut.
Symptoms of a Failing Keyless Entry Transmitter
When a key fob for a 2017-2024 Chrysler Pacifica or 2020-2024 Chrysler Voyager begins to fail, the symptoms are usually very noticeable. Here are the most common issues, from the most likely to the least.
1. "Key Fob Not Detected" Message
This is the most frequent complaint. When you try to start the vehicle, a message appears on the instrument cluster stating the key fob is not detected. In most cases, this is simply due to a weak or dead battery inside the fob itself. The vehicle cannot receive a strong enough signal to verify the key's presence. In some cases, this can also be caused by a weak main vehicle battery or a problem with the car's receiver module.
Pro Tip: If you see the "Key Fob Not Detected" message and cannot start the vehicle, you can use an emergency override. Press the brake pedal, then push the Start/Stop button using the nose of the key fob (the end opposite the metal emergency key). The vehicle's antenna can read the transponder chip at this very close range even if the fob's battery is dead.
2. Intermittent or Unresponsive Buttons
The buttons for locking, unlocking, opening doors, or remote start may work only sporadically or stop working altogether. You might have to press a button multiple times or get closer to the vehicle for it to register. This is also a strong indicator of a failing internal battery.

For vehicles equipped with proximity entry (where you can unlock the door by touching the handle with the fob in your pocket), you may notice that it fails to work unless the fob is very close to the door. This can also affect the remote start range. A Technical Service Bulletin (TSB) was issued for this specific concern.
Known Issues, TSBs, and Recalls
TSB for Decreased Remote Range
Chrysler issued Technical Service Bulletin S2208000138RevA for some Pacifica models experiencing decreased range for the remote start and Remote Keyless Entry (RKE) functions. This issue could also cause the Tire Pressure Monitoring System (TPMS) values to not display correctly. The fix involves a software update or potential replacement of the remote start antenna module. 🎬 Watch: How to reset your RF hub and antenna module If you experience poor range even with a new battery, mention this TSB to your dealership or technician.
Vehicle Recalls (Note: Not for Key Fob)
While there have been several recalls for the Chrysler Pacifica, particularly for the Plug-in Hybrid (PHEV) models concerning fire risk from the high-voltage battery, there are no active recalls for the keyless entry transmitter itself. These vehicle recalls do not affect the function or replacement of the key fob.
Programming and Installation
Warning: This key fob MUST be professionally programmed to your vehicle. It is not a DIY-capable part. The programming process links the unique transponder chip inside the fob to your vehicle's immobilizer system. Without this step, the remote will not start the car.
Who Can Program This Key Fob?
- Dealerships: Chrysler and Dodge dealerships have the required diagnostic tools (wiTECH) to program new key fobs to your Pacifica or Voyager.
- Automotive Locksmiths: Most professional automotive locksmiths have advanced tools that can also program these smart keys, often at a competitive price.
You cannot program this key yourself using an onboard procedure. The vehicle's security system requires a specialized diagnostic tool to access the programming functions.
Buying a Used Keyless Entry Transmitter
Purchasing a used OEM key fob can be a cost-effective option, but it requires careful verification to avoid compatibility issues. A used original part is often more reliable than a cheap aftermarket alternative.
How to Ensure Compatibility
- Check the FCC ID: The most important step is to match the FCC ID on the back of your original remote. For these Pacifica and Voyager models, the correct FCC ID is M3N-97395900. Do not purchase a remote with a different FCC ID, even if it looks identical.
- Verify the Button Count: This is a 7-button smart key. Ensure the replacement has the same functions as your original (Lock, Unlock, Remote Start, Left Sliding Door, Right Sliding Door, Rear Hatch, Panic).
- Part Numbers: The OEM part number is typically 68217832AD, which supersedes older versions like 68217832AB and 68217832AC. Any of these will work if the FCC ID is correct.
Important Considerations for Used Fobs
Warning: Many used key fobs are electronically "locked" to the vehicle they were originally programmed to. Before a locked fob can be programmed to your vehicle, it must be unlocked or "re-flashed" by a locksmith with specialized equipment. Always confirm with the seller that the used fob is in an unlocked or virgin state, or factor in the potential cost of having it unlocked.
- Emergency Key Blade: A used fob will come with a key blade that is already cut for another vehicle. You will need to purchase a new, uncut emergency key blade and have it cut by a locksmith to match your vehicle's door lock.
- Physical Condition: Inspect the used fob for cracks in the casing or excessive wear on the button icons. Check the battery compartment for any signs of corrosion, which could indicate water damage.

Frequently Asked Questions (FAQ)
Can I program a new Chrysler Pacifica or Voyager key fob myself?
No. These vehicles have a complex security system that requires specialized diagnostic equipment to program new keys. You must have it done by a Chrysler dealership or a qualified automotive locksmith.
Why does my van say "Key Fob Not Detected"?
The most common reason is a dead or weak battery in the key fob (it uses a CR2032 battery). Other potential causes include radio frequency interference from other devices, a weak main car battery, or a fault in the key fob or the vehicle's receiver.
Can a locksmith program this key instead of the dealer?
Yes, most professional automotive locksmiths have the necessary tools and software to program smart keys for the Pacifica and Voyager. Their pricing is often competitive with the dealership.
What do I do if my key fob battery dies and I can't get in or start my van?
Your key fob contains a hidden metal emergency key. Press the small button on the side to release it. Use this key to manually unlock the driver's door. To start the engine, press the brake pedal and push the Start/Stop button with the top of the key fob itself. This allows the car to read the internal chip even without battery power.
