SUPALAND Mercedes Replacement Key Fob 4-Button 1997–2014 Fits C E S ML GL R SL Sprinter — Blank Remote with Battery & Board, Ready

This SUPALAND 4-button replacement key fob is a ready-to-program remote that fits Mercedes-Benz 1997–2014 models (IYZ3312 / IYZDC) and ships with the electronic board and battery pre-installed.

If your Mercedes keyless remote is lost, cracked, or no longer communicating with the car, this SUPALAND replacement fob offers a cost-effective way to restore remote locking and unlock functions. The shell arrives fully assembled with the internal circuit board and battery already fitted and tested, but it is sold as a blank remote that must be cut (if you need a metal blade) and professionally programmed to your vehicle. This listing covers many Mercedes-Benz lines and the Sprinter 300, so confirm your OEM FCC ID, part number, and button layout before ordering.

Which Mercedes models and years will this fob fit?

This key fob is made to match the original FCC P/Ns IYZ3312 and IYZDC and supports a wide span of Mercedes-Benz vehicles from 1997 through 2014, including C, CL, E, GL, ML, R, S, SL series and Sprinter 300 models. Compatibility depends on matching the OEM markings and button design.

• Fits Mercedes years 1997–2014 across C-Class, E-Class, S-Class, SL, CL, ML, GL, R-Class.
• Compatible with Sprinter 300 and many 300 series variants—verify FCC ID IYZ3312 / IYZDC.
• Confirm your vehicle’s key part number, frequency, and button layout before purchase.

How is the fob delivered and what comes pre-installed?

Each fob arrives brand-new and fully assembled: the electronic circuit board and a battery are already installed and the unit has been bench-tested prior to shipping. The product is a blank keyless remote, so it does not include cutting or immobilizer programming services.

• 1 complete 4-button remote with circuit board and battery included.
• Quality-tested before shipping to ensure the electronics power on and buttons register.
• Blank key blade (if pictured) may require cutting to match your ignition or valet key.

Will I be able to program this fob myself?

These Mercedes models are not typically programmable using only on-board vehicle menus; programming generally requires dealer-level equipment or a professional locksmith with the right diagnostic tools. If you don’t have access to specialized programming equipment, plan to use a qualified service to enable remote functions with your car’s immobilizer.

• Not on-board programmable—professional programming or dealership visit recommended.
• Programming links the fob’s transponder to your vehicle’s immobilizer system.
• Contact SUPALAND or your dealer with FCC ID and part numbers for guidance.

Who this is for: Drivers or technicians who need a cost-effective replacement remote shell and electronics for older Mercedes-Benz or Sprinter vehicles, and who are prepared to have the key blade cut and the transponder programmed by a locksmith or dealership. This unit is ideal if your original remote is damaged but you want a complete, tested assembly ready for installation, rather than repairing individual electronic components.
