DAS-2 and DAS-3 (1997-- 2014): These older infrared secrets are simpler for specialized locksmiths to program. Many independent professionals with the right diagnostic tools can "check out" the data from the Ignition Control Unit (EIS) and program a brand-new key.FBS4 System (2015-- Present): This is the current security version. It is considerably more secure and has actually historically been "locked" to the Mercedes-Benz business servers. For many years, only licensed car dealerships might order secrets for FBS4 cars.

When a key is configured to a VIN, it can not be typically "un-programmed" or recycled on another car. Buying an utilized key is usually a waste of cash unless the owner is just searching for a replacement plastic shell for their existing internal circuit board.
Uncertified Mobile Locksmiths
Some locksmiths declare they can manage Mercedes-Benz however show up with tools implied just for Ford or Toyota. This can lead to a "bricked" EIS, suggesting the car's ignition system becomes entirely non-functional. Constantly ask particularly: "Do you have the software application to set a Mercedes DAS-3 system?"
FREQUENTLY ASKED QUESTION: Frequently Asked Questions
Q: Can I set a Mercedes key myself?A: Generally, no. Unlike some older domestic cars that allow "onboard programming" via a sequence of button presses, Mercedes-Benz requires specialized hardware that interfaces with the car's OBD-II port or the EEPROM chip inside the ignition.
