Selecting the correct Aftermarket Remote Key Fob for a multi-make vehicle lineup requires careful attention to each platform’s distinct remote protocol. Because this product spans several incompatible key systems, locksmiths and vehicle owners should verify exact part-number compatibility before ordering. The Aftermarket Remote Key Fob listed under this SKU covers models from Mercedes-Benz, Nissan, Land Rover, Porsche, RAM Trucks, and Toyota — each with its own immobilizer architecture and remote frequency. Before committing to this unit, confirming that the fob matches the target vehicle’s receiver module and transponder requirements is essential.

Validated Vehicle Fitments for the Aftermarket Remote Key Fob

This SKU has been validated against the following vehicles and model-year ranges:

• Mercedes Sprinter (2006–2019) — A commercial-class van platform that transitioned through multiple key system generations across this span.
• Nissan Rogue (2014–2018) — A compact crossover that typically uses a proximity-style or traditional remote entry system depending on trim level.
• Land Rover Discovery (2004–2009) — An SUV platform that employed passive entry remotes during these model years.
• Land Rover Range Rover Sport (2005–2013) — Shares a remote architecture with other Land Rover products of this era but may differ in button layout and rolling-code protocol.
• Land Rover Range Rover (2002–2012) — The flagship full-size SUV, which saw at least one major key system overhaul during this decade-long window.
• Land Rover Range Rover Vogue (2002–2012) — Market-variant badging of the Range Rover, typically using identical key hardware.
• Porsche Boxster (2005–2012) — A mid-engine sports car with its own distinct immobilizer and remote receiver module.
• RAM Trucks ProMaster (2023) — A full-size van platform that may share remote architecture with other Stellantis commercial vehicles.
• Toyota ProAce Max — A light commercial vehicle sold primarily in European markets.

Given the range of makes and model years, it is critical to recognize that a single fob shell or circuit board is unlikely to serve all of these vehicles interchangeably. The remote must be matched to the specific vehicle’s receiver frequency, rolling-code algorithm, and immobilizer transponder type. Locksmiths should treat each application as a separate verification task.

Important Considerations Before Purchase

Because this product spans five different automotive manufacturers, no single set of technical specifications — chip type, operating frequency, or FCC certification — can be stated that applies uniformly across all fitments. Each vehicle platform listed above uses a proprietary or semi-proprietary communication protocol between the remote and the body control module. The fob intended for a Land Rover Range Rover Sport will not program to a Nissan Rogue, and vice versa.

When sourcing aftermarket remotes that cover a broad fitment list like this one, the safest approach is to cross-reference the vehicle’s existing key part number or FCC ID (printed on the back of the original remote) with the aftermarket replacement listing. Automotive locksmiths with access to key-programming platforms such as Autel, Xtool, or SmartPro can typically look up the OEM part number and match it to a verified aftermarket equivalent before ordering.

Programming and Professional Guidance

Programming an aftermarket remote to any of the listed vehicles will require a diagnostic tool capable of communicating with that platform’s immobilizer module. On-board programming (using ignition-cycle sequences without external tools) is available for some of these vehicles, but many — particularly the Land Rover and Porsche models — mandate dealer-level or advanced locksmith tooling for remote enrollment.

Vehicle owners who are not equipped for key programming should consult a qualified automotive locksmith. A professional can confirm the correct remote variant, cut or laser-etch any integrated blade to the proper keyway, and complete the enrollment procedure so the fob communicates reliably with the vehicle.

Because aftermarket remotes vary in build quality and internal component sourcing, testing range and button responsiveness immediately after programming is recommended. If the remote exhibits reduced range compared to the original, a replacement battery or antenna alignment issue may be the cause.
