2004 Mercedes-Benz Ml-Class
Key Replacement - Save vs Dealer in San Diego

Scam locksmiths target Mercedes owners specifically because they know you are stressed and the car is expensive. One owner described a locksmith who showed up, blamed "Mercedes ransomware," could not actually program the key, and the owner ended up paying $1,000 at the dealer for a Smart car key. Another locksmith forum post described a "new guy in town" who advertised Mercedes key work, pulled the EIS apart, failed the job, and turned a $400 fix into a $1,200 mess. A real Mercedes locksmith will quote a firm price for your 2004 Mercedes-Benz Ml-Class over the phone and tell you exactly what tools they use. We have over 100,000 followers across our YouTube and TikTok channels showing exactly how we do the work.

Yes. When we program a Remote Head Key for your 2004 Mercedes-Benz Ml-Class, it communicates with your vehicle's EIS/EZS module the same way the factory key does. The engine starts, the doors lock and unlock, and keyless go functions work as expected. We test every key on the spot before we leave. One Mercedes owner had the dealer try three shop keys and two newly coded fobs before concluding the EIS was corrupt, costing them multiple visits and days of troubleshooting. We diagnose and verify everything in one visit.

The 2004 Mercedes-Benz Ml-Class uses a CR2025 battery. We always install a fresh one when we make a replacement key. If you already have a key and the range seems short or the buttons are inconsistent, a dead battery is the most common cause. On Mercedes keyless go models, the car will display a specific "replace key battery" warning before the key stops being detected. It is a quick, cheap fix before assuming you need a full replacement.

Every key we make comes with a warranty. If the key stops working, the remote functions drop, or anything is off, call us and we take care of it. We are a local business in Alpine, not a random call center sending whoever is closest. Mercedes owners describe the dealer experience as paying $600 to $1,500 and still having issues. One owner tried for almost two months to get a working key through the dealer because cases kept timing out. When you go through EZ Car Keyz, you have a real person and a real business standing behind the work.
