USARemote 4-Button Key Fob Replacement Set (M3N5WY72XX) — Set of 2, Complete Preassembled Fobs with Batteries

If your factory key fob is cracked, worn, or nonfunctional, this pair of replacement key shells from USARemote is designed to restore remote locking, unlocking, and panic functions for select Chrysler Pacifica, Grand Caravan, Town & Country and Jeep Liberty vehicles. Each unit arrives as a complete electronic assembly with battery installed, matching the OEM M3N5WY72XX footprint so you won’t have to transfer small components. These are user-programmable when you have two original working keys; if only one working key is available, professional programming by a locksmith or dealer will be required.

How do I program these replacement key fobs?

USARemote includes step-by-step programming instructions for user programming when you have two original functioning keys. The on-vehicle programming sequence is straightforward for many owners, but if you only possess one original key, professional programming is necessary.

• Included instructions outline the vehicle’s ignition and button sequences for programming.
• Two original keys are required for DIY programming as noted in the directions.
• If you have only one original key, visit a locksmith or dealership for programming assistance.
• Programming time typically takes just a few minutes for qualified users or technicians.

What comes in the box and what condition are components in?

Each box contains two complete, pre-assembled key fobs with the electronic circuit board and battery already installed. You won’t need to transplant tiny parts or solder anything; the housings are ready to use once cut to match your mechanical key blade and programmed to your vehicle.

• Set of 2 complete electronic assemblies with batteries installed for immediate use.
• Durable ABS housings with four-button layout matching OEM shape and function.
• Instructions included for user programming when two original keys are available.
• Mechanical key blades may require cutting to match your vehicle’s ignition lock.

Will this replace both the electronics and the physical key blade?

The package provides the electronic remote assembly and housing; mechanical blades are typically supplied but must be cut to your vehicle’s key code or existing key. The product restores remote functions electronically while the blade restoration is handled separately by a locksmith or key-cutting service.

• Electronics and battery included—no need to source small internal parts.
• Mechanical blades need to be cut to match your vehicle’s key profile.
• Combine with professional key cutting for full replacement readiness.
• After cutting and programming, fobs function like original remotes for lock/unlock/panic.

Who is this for: This USARemote replacement is a practical DIY-friendly solution for owners of 2004–2008 Chrysler Pacifica or 2005–2007 Jeep Liberty models who need to replace worn or broken remotes without buying dealer-priced units. It’s ideal for someone comfortable having keys cut by a locksmith and following on-vehicle programming steps when two working keys are present, or for anyone who prefers to have a locksmith or dealership handle final programming.
