SUPALAND Replacement Key Fob for Mercedes & Sprinter 1997–2014 — 4-Button IYZ3312, Ready-to-Program

SUPALAND's four-button replacement key fob is a ready-to-program, drop-in remote compatible with Mercedes-Benz and Sprinter models using FCC IYZ3312 / IYZDC (1997–2014).

If your original Mercedes keyless remote is lost, damaged, or no longer communicating, this SUPALAND replacement fob offers the same button layout and electronics used by many 1997–2014 Mercedes-Benz and Sprinter vehicles. The unit ships fully assembled with its electronic board and battery installed and has been bench-tested for basic function. Because these vehicles require dealer-grade or specialized programming tools, the fob is sold as a blank that must be programmed and, where applicable, have its metal key blade cut by a locksmith or dealership.

Which Mercedes and Sprinter models will this replacement fob fit?

This SUPALAND key fob is designed to match the OEM specifications for multiple Mercedes model families across model years 1997 through 2014. It targets C-Class, E-Class, CL, S-Class, G-Class, M-Class/ML, R-Class, SL series, and Sprinter 300 models that originally used the IYZ3312 / IYZDC remote electronics.

• Compatible model families: C, E, CL, S, G, M/ML, R, SL, Sprinter 300.
• Covered years: 1997–2014 (verify specific year and trim compatibility).
• Match point: check FCC ID and part number on your original fob.
• Visual match: four-button layout consistent with many OEM remotes.

How does programming and installation work?

These Mercedes and Sprinter models are not programmable by simple in-car procedures; programming requires specialized diagnostic equipment or dealer/key-service tools to write the correct transponder and remote codes. SUPALAND supplies the electronic board and battery pre-installed, but you should plan to have a locksmith or dealership complete remote synchronization and blade cutting.

• Programming: requires dealer or professional key programmer.
• Included: 1 fully assembled fob with battery and electronic board.
• Key blade: blank and may need cutting to your vehicle’s ignition.
• Support: contact SUPALAND or your dealer for OEM information matching.

What should I check before ordering to ensure compatibility?

To avoid returns or extra trips to the dealer, confirm the FCC ID, part number, and frequency printed on your original remote match IYZ3312 / IYZDC. Also compare the button layout and physical housing style to ensure the replacement will sit and operate correctly in your vehicle’s key slot or keyfob storage area.

• Verify FCC ID and part number on your existing remote.
• Compare frequency and transponder type if available.
• Ensure the four-button layout visually matches your OEM fob.
• When unsure, ask a dealer or contact SUPALAND with photos for confirmation.

Who is this for: This SUPALAND fob is aimed at Mercedes-Benz and Sprinter owners (1997–2014) who need an OEM-style replacement remote and are prepared to have it professionally programmed and cut. It’s ideal for people replacing a lost or non-working remote who want a tested, complete electronic assembly ready for programming. If you need a plug-and-play, in-car-programmable remote, this product may not be suitable; consult a locksmith or dealer for vehicles with different programming requirements.
