Because of the high danger of lorry theft, neither a dealership nor a reliable locksmith professional will supply a key without strict documents. Ownership must be validated beyond a doubt. Needed items usually consist of:
Valid Driver's License: Must match the name on the registration.Car Registration or Title: To show the person requesting the key owns the car.The Vehicle Itself: In a lot of modern-day cases, the car needs to be present to sync the brand-new key to the onboard computer.VIN (Vehicle Identification Number): Found on the control panel or the chauffeur's side door jamb.What to Do If You Lose Your Only Key
Losing the only key to a Mercedes-Benz is a stressful experience. To lessen the headache, follow these sequential actions:
Verify the Loss: Check all pockets, bags, and the area around the lorry. Don't forget to check the trunk if you were just recently loading groceries.Determine Your System: If the car is pre-2013, call a customized European locksmith first. It might conserve you a ₤ 200 towing charge to the dealership.Contact the Dealer if Locksmiths Fail: If your car is a more recent design (FBS4), call the parts department of your local Mercedes-Benz dealer with your VIN prepared.Get ready for a Tow: Many dealerships require the car to be on-site to "marry" the brand-new key to the ECU.Order a Spare: Once the immediate crisis is dealt with, always buy a 2nd key. The cost of a spare key is significantly lower than the cost of a "lost all keys" emergency situation service.Important Warning: Buying Keys on eBay or Amazon
A common mistake owners make is buying a used Mercedes key from an auction website for ₤ 30, thinking they can have it reprogrammed. In practically all cases, this is a waste of cash.

Mercedes SmartKeys are "write-once" chips. Once they are set to a specific VIN, they are locked. While some innovative "virginizing" of chips is possible for older FBS3 secrets, it is technically difficult and many locksmiths refuse to do it due to the fact that the dependability is low. Always purchase a brand-new, unprogrammed "virgin" key from a trusted professional source.

Not always. This could be a concern with the Electronic Steering Lock (ESL) or the Electronic Ignition Switch (EIS). This is a common fault in certain designs like the W204 C-Class.
Last Thoughts
Changing a Mercedes-Benz key is a premium service for a premium lorry. While the costs can be high-- ranging anywhere from ₤ 300 to nearly ₤ 1,000 depending on the model-- the security used by the Mercedes Driver Authorization System is top-tier. To avoid the tension of a "overall lockout," owners are motivated to keep at least 2 working secrets at all times and to ensure their key fob batteries are changed annually. When a replacement is unavoidable, picking between a dealer and an expert locksmith professional stays an option in between official certification and prospective cost-saving benefit.
