The Evolution of the Mercedes-Benz Key
To comprehend why replacing a Mercedes key is a specialized job, one should comprehend the development of the "SmartKey." Mercedes-Benz moved far from conventional metal blades in the late 1990s, presenting the electronic ignition system.
Traditional Keys (Pre-1997): These were standard metal keys, though later on variations included a transponder chip for standard immobilizer functions.SmartKey (1998-- Present): These utilize infrared signals rather than a physical blade to begin the car. They belong to the FBS (Fahrberechtigungssystem) or Driver Authorization System.Keyless-Go: An advancement of the SmartKey that enables the chauffeur to unlock and start the automobile while the key stays in their pocket.Digital Key: Available on newer models, allowing smart devices to act as the main access point.Why You Can not Simply "Cut" a New Key
Mercedes-Benz utilizes a security system known as FBS. The most typical systems presently in use are FBS3 and FBS4.
FBS3: Found in models approximately from 1998 to 2014. These secrets can often be set by specialized automobile locksmiths who have the appropriate diagnostic tools.FBS4: Introduced around 2013/2014. This system is substantially more secure. For an extended period, FBS4 keys could only be bought through a licensed car dealership since the programming needed a "handshake" with the Mercedes-Benz central servers in Germany.
Because each key is uniquely synced to the car's Electronic Ignition Switch (EIS) and Engine Control Unit (ECU), a blank key from the internet will not work without top-level shows.

The expense of an extra key is considerably lower than the cost of a "lost all secrets" emergency service.Crucial Warning: Buying Keys on eBay or Amazon
A common mistake owners make is acquiring an utilized Mercedes key from an auction site for ₤ 30, believing they can have it reprogrammed. In practically all cases, this is a waste of cash.

Mercedes SmartKeys are "write-once" chips. Once they are configured to a specific VIN, they are locked. While some sophisticated "virginizing" of chips is possible for older FBS3 secrets, it is technically challenging and lots of locksmith professionals refuse to do it because the reliability is low. Constantly buy a new, unprogrammed "virgin" key from a trusted expert source.

Last Thoughts

While the expenses can be high-- ranging anywhere from ₤ 300 to almost ₤ 1,000 depending upon the model-- the security provided by the Mercedes Driver Authorization System is top-tier. To prevent the tension of a "overall lockout," owners are encouraged to preserve a minimum of 2 working keys at all times and to guarantee their key fob batteries are replaced each year.
