Mercedes-Benz Key Programming & Replacement
Cedar Automotive — Cedar Rapids, IA
Mercedes-Benz Key Programming Without the Dealer Wait
Lost your Mercedes-Benz key, locked out, or need a spare programmed? Cedar Automotive handles Mercedes-Benz key programming, EIS/EZS (Electronic Ignition Switch) coding, FBS (Fahrberechtigungssystem) immobilizer work, and key fob replacement for W204, W205, W211, W213 and related chassis — all at our Cedar Rapids shop, at a fraction of dealer pricing.
Mercedes key security is the tightest in the industry and changes generation to generation. Older W211 and W204 cars rely on the original EIS/EZS with personalized key tracks that must be read and rewritten. W205 C-Class and W213 E-Class add FBS3 and FBS4 encryption, which require token-based programming and a healthy ignition switch to complete. We carry Mercedes-specific programmers, EIS renewal tools, and personalization equipment needed across all of these platforms, including all-keys-lost procedures when every original key is gone.
Mercedes-Benz dealers often quote weeks of lead time and dealer-level pricing for key work. We work on your VIN directly, verify EIS and FBS generation before starting, and handle cutting, programming, and verification in one visit. Call (319) 450-7584 with your VIN for an exact quote.

Mercedes-Benz Key Programming FAQ
Can you program a Mercedes-Benz key without going to the dealer?
Yes. Cedar Automotive has the Mercedes-specific diagnostic equipment needed to program keys for W204, W205, W211, W213 and related chassis. We handle all-keys-lost, spare key addition, and key fob replacement at a fraction of Mercedes-Benz dealer pricing. Call (319) 450-7584 to confirm compatibility for your VIN.
Do you work on EIS/EZS and FBS immobilizer systems?
Yes. We diagnose and code Mercedes-Benz EIS/EZS (Electronic Ignition Switch) and FBS (Fahrberechtigungssystem) immobilizer faults, including EIS renewal, personalized EIS replacement, and key synchronization after ignition switch or control module replacement. If a replacement EIS is required, we source and program the unit in-house.
How much does Mercedes-Benz key programming cost?
Pricing depends on model year, chassis (W204 vs W213 differs significantly), and whether this is a spare key or all-keys-lost. W204 and W205 are straightforward; W213 with newer FBS4 encryption takes longer. Call with your VIN at (319) 450-7584 for an exact quote before any work begins.
Do you come to me or do I bring the car in?
Mercedes-Benz key programming is done at our shop at 1407 Adair Ct SW Suite 101 in Cedar Rapids, IA. EIS/EZS programming requires the vehicle, the key, and OBD-II access under stable power. If the vehicle is immobile and locked, call us to discuss tow-in options.
