Used across the Chrysler Cirrus, Chrysler Sebring, Chrysler Stratus, and Dodge Stratus platforms from 1995 to 2000, the Chrysler Remote Key Fob (FCC ID KYPT03C98JA) serves as the wireless remote entry device for these mid- to late-nineties vehicles. Each Chrysler Remote Key Fob (FCC ID KYPT03C98JA) transmits on 315 MHz to communicate with the vehicle’s receiver module, handling door lock and unlock functions from a distance. For technicians servicing these now-aging platforms, the fob is a straightforward radio-frequency remote without the layered security complexity found in later-generation Chrysler systems. A properly synced Chrysler Remote Key Fob (FCC ID KYPT03C98JA) restores full wireless convenience to these vehicles, making it a practical component for owners who want to maintain remote entry functionality.

Vehicle Compatibility for the Chrysler Remote Key Fob (FCC ID KYPT03C98JA)

The FCC-registered ID KYPT03C98JA maps to a specific set of Chrysler and Dodge vehicles produced during the second half of the 1990s. The confirmed fitment list includes:

• Chrysler Cirrus — model years 1995 through 2000
• Chrysler Sebring — model years 1995 through 2000
• Chrysler Stratus — model years 1995 through 2000
• Dodge Stratus — model years 1995 through 2000

These four nameplates shared a common platform architecture during this era, which is why a single FCC-registered remote design covers all of them. The Cirrus, Sebring sedan and convertible, Chrysler Stratus (sold predominantly outside the US market under that badge), and the Dodge-branded Stratus all utilized the same receiver module and frequency pairing. When sourcing a replacement, confirming the FCC ID printed on the back of the original unit ensures the correct match.

Operating Frequency and Signal Characteristics

This remote operates on the 315 MHz band, which was the standard frequency allocation for North American automotive keyless entry systems during the 1990s. The 315 MHz signal is picked up by the vehicle’s radio-frequency receiver, typically mounted inside the cabin near the rearview mirror area or integrated into the body control module, depending on model-year configuration. Range will vary based on battery condition and environmental factors, but a healthy unit typically achieves reliable activation within 30 to 50 feet under open-air conditions.

Because this is a unidirectional remote — it sends a signal but does not receive one back — there is no rolling-code handshake of the type found in later Chrysler proximity key systems. The device uses a fixed or learn-code protocol consistent with mid-1990s Chrysler engineering. This simplicity is actually an advantage from a serviceability standpoint: programming does not require expensive dealer-level scan tools in most cases.

Programming and Synchronization

Enrolling the fob to a vehicle generally follows a manual on-board procedure. On most 1995–2000 Chrysler and Dodge vehicles in this platform family, the synchronization sequence involves cycling the ignition key and pressing buttons on the remote in a timed pattern. The exact steps can vary slightly depending on model year and whether the body control module has been replaced or reflashed, so referencing the service manual for the specific vehicle is always recommended.

Automotive locksmiths working on these vehicles should note that the receiver module must be in “learn mode” before this remote will pair successfully. If the module has stored the maximum number of remotes (typically two), the oldest stored code will be overwritten or all codes may need to be cleared before a new unit can be enrolled. It is standard practice to have all remotes the customer intends to use present during the programming session so each one can be registered in sequence.

No additional aftermarket programming hardware is strictly required for basic remote synchronization on these platforms. However, if the body control module has failed or been swapped from a salvage vehicle, a diagnostic scan tool capable of communicating with the Chrysler CCD or PCI data bus may be needed to reset the module before remote learning will function.

Battery and Maintenance Considerations

The device uses a standard coin-cell battery, accessible by separating the two halves of the remote housing. Over time, the rubber button pad can degrade, leading to intermittent button response even when the battery is fresh. Replacement button pads and housings are available in the aftermarket and can restore tactile function without needing to replace the entire circuit board.

For vehicles that have sat unused for extended periods, the receiver module itself can sometimes lose its stored remote codes if the vehicle battery was fully discharged or disconnected. In those situations, re-synchronizing the fob using the on-board learn procedure will restore wireless entry without any parts replacement.

OEM Versus Aftermarket Replacement

Original-equipment remotes carrying the KYPT03C98JA FCC ID are no longer manufactured by Chrysler, given that the newest compatible vehicle is over two decades old. Aftermarket clones bearing the same FCC ID are available and generally function identically, provided the internal circuit board matches the original frequency and code protocol. When purchasing a replacement, verifying the FCC ID on the unit itself — not just the listing description — is the most reliable way to confirm compatibility.

Aftermarket units may differ in housing quality, button feel, and battery contact durability. For owners who want the closest match to original fit and finish, new-old-stock (NOS) OEM remotes can occasionally be found, though pricing tends to reflect their scarcity.

When to Contact a Locksmith

While the on-board programming procedure for this remote is within reach of a mechanically inclined vehicle owner, there are scenarios where professional locksmith assistance makes the process faster and more reliable. If the vehicle’s body control module has been replaced, if neither of the owner’s existing remotes will sync, or if the on-board learn sequence simply will not initiate, a mobile automotive locksmith with Chrysler platform experience can diagnose the underlying issue. Locksmiths carry the diagnostic tools needed to communicate directly with the body control module, verify stored codes, and clear faults that may be blocking the learn mode.

For vehicles in the 1995–2000 Chrysler Cirrus, Sebring, Stratus, or Dodge Stratus family, professional key and remote services remain a cost-effective way to restore full functionality without a dealership visit.
