Lear 3-Button Remote Key Fob (FCC ID GQ43VT9T) – Specs & Fitment

Fitments for the Lear 4-Button Remote Key Fob (FCC ID KOBLEAR1XT) – Fitment & 3-Button Remote Key Fob (FCC ID GQ43VT9T) span a wide range of Chrysler, Dodge, and Jeep platforms produced between 1994 and 2010. The fob covers models including the Chrysler Concorde, Chrysler LHS, Chrysler PT Cruiser, Dodge Dakota, Dodge Durango, Dodge Intrepid, Dodge Neon, Dodge RAM, and Jeep Grand Cherokee. Across these vehicles, the Lear 3-Button Remote Key Fob (FCC ID GQ43VT9T) handles lock, unlock, and panic functions via a 315 MHz RF signal directed at each vehicle’s receiver module. Owners replacing the device should expect an on-board programming sequence or a locksmith-assisted procedure depending on model year and trim. When ordering a Lear 3-Button Remote Key Fob (FCC ID GQ43VT9T), confirm the FCC ID printed on the back of the existing unit to ensure an exact match.

Vehicle Compatibility for the Lear 3-Button Remote Key Fob (FCC ID GQ43VT9T)

This remote is validated across three DaimlerChrysler-era brands. Below is the complete fitment breakdown by make, model, and year range:

• Chrysler Concorde — 1998 through 2004
• Chrysler LHS — 1999 through 2001
• Chrysler PT Cruiser — 2001 through 2010
• Dodge Dakota — 1997 through 2004
• Dodge Durango — 1998 through 2003
• Dodge Intrepid — 1998 through 2004
• Dodge Neon — 2000 through 2005
• Dodge RAM — 1994 through 2002
• Jeep Grand Cherokee — 1999 through 2004

The year ranges above represent the model years for which this FCC ID has been validated. Production-run overlap means some early or late model-year vehicles may have shipped with a different remote part number, so physical verification of the existing fob’s FCC ID sticker is the most reliable cross-reference method.

Technical Specifications

The unit operates on a 315 MHz carrier frequency, which is standard for North American keyless entry remotes of this era. It features three buttons: Lock, Unlock, and Panic. The FCC ID GQ43VT9T is registered to Lear Corporation, which manufactured a significant volume of keyless entry hardware for Chrysler Group vehicles throughout the late 1990s and 2000s. This remote is a standalone keyless entry transmitter — it does not contain an integrated key blade or ignition transponder within the fob housing itself.

Because the fob is purely a remote transmitter, it pairs with the vehicle’s radio-frequency receiver module rather than the engine immobilizer system. The distinction matters for locksmiths and technicians: programming this device is a receiver-pairing procedure, not a transponder registration. The two processes are separate on the Chrysler platform, and confusing them is a common source of diagnostic frustration.

Programming Procedures and Considerations

Most of the vehicles covered by this remote support an on-board programming (OBP) sequence that does not require a scan tool. The general procedure for Chrysler, Dodge, and Jeep vehicles of this generation involves cycling the ignition between the ON and OFF positions within a timed window, then pressing a button on the fob when the door locks cycle to indicate programming mode has been entered. The exact number of ignition cycles, the timing window, and the confirmation signals vary by platform. For instance, the Jeep Grand Cherokee procedure differs slightly from the Dodge RAM sequence in both the number of key turns and the position of the driver-side door during the process.

A few important caveats apply when programming the remote:

• Existing remotes must be reprogrammed. On these Chrysler-platform receivers, entering programming mode erases all previously stored remote codes. Every remote the owner wants to use — including any previously working units — must be reprogrammed during the same session.
• Maximum remote capacity. The receiver modules in these vehicles typically accept up to four paired remotes. Attempting to pair a fifth unit will overwrite the first stored code.
• Battery condition. A weak battery in the fob can cause intermittent pairing failures. Fresh CR2032 cells (or the battery type specified for the particular housing variant) should be installed before beginning the programming sequence.

For situations where OBP does not succeed — for example, if the vehicle’s receiver module has been replaced or reprogrammed by a dealer — a diagnostic scan tool with Chrysler SCI or CCD bus access can force the receiver into learn mode. Automotive locksmiths equipped with aftermarket programmers that support legacy Chrysler protocols can handle this without a dealership visit.

OEM vs. Aftermarket Considerations

Original Lear-manufactured units bearing the GQ43VT9T FCC ID remain available through replacement-parts channels. Aftermarket clones using the same FCC ID and frequency are also widely produced. From a functional standpoint, aftermarket versions generally perform identically because the RF protocol used by these Chrysler-era receivers is a straightforward rolling-code system without the more complex encryption layers found in later-generation smart keys.

The primary differences between OEM and aftermarket units tend to be in case quality, button tactile feel, and long-term durability of the rubber keypad. Locksmiths who stock these remotes in volume often carry aftermarket versions for cost efficiency, while customers who prefer OEM fit and finish can source genuine Lear-branded replacements. Either way, the programming procedure is identical — the receiver does not distinguish between OEM and aftermarket transmitters as long as the RF characteristics and rolling-code algorithm match.

When to Contact a Locksmith

Vehicle owners who are comfortable following a timed ignition-cycling procedure can often program this remote at home. However, professional locksmith assistance is advisable in several scenarios: when the on-board procedure repeatedly fails, when the receiver module has been swapped or lost its configuration data, or when the owner has no working remote to validate that the receiver is functional. A qualified automotive locksmith can also verify that the replacement fob’s frequency and rolling-code format are correct before beginning the pairing process, saving time and eliminating guesswork.

For vehicles in the fitment list above — particularly high-mileage Dodge RAM trucks and Jeep Grand Cherokees that may have been through multiple owners — confirming the FCC ID on the existing remote (or the receiver module part number under the dash) is the fastest path to a successful replacement.
