Identify the fault before replacing a key
Does your Mercedes unlock but refuse to start, or start while its remote buttons no longer work? Describe those behaviours separately. A remote fault, recognition problem and vehicle malfunction do not necessarily call for the same intervention.
Mention drops, exposure to water and any displayed message. If you have a second key, explain how it behaves without dismantling the first one. This helps establish whether you need repair, a spare or further assessment beforehand.
Electronic keys and KEYLESS-GO functions
A Mercedes key cannot be selected by counting its buttons. The vehicle generation and equipment determine the usable reference and available preparation. An emergency blade, where fitted, does not on its own replace electronic permission to start.
Tell us at the outset if your car has KEYLESS-GO. We clarify which functions will be retained and tested. Some versions require manufacturer procedures; these limits are explained before arranging an unsuitable job.
A spare for a passenger car or commercial vehicle
For a usable A-Class, E-Class or GLC, a spare can be arranged before the last key disappears. If a Vito or Sprinter is stranded, describe its location and access to the parking area.
Mobile service in Geneva and Vaud is agreed after the vehicle details have been reviewed. Your quote specifies functions, preparation work and travel arrangements. You will need to demonstrate your right to access the vehicle.
Models to discuss with us
A-Class, B-Class, C-Class, E-Class, S-Class, CLA, CLS, GLA, GLB, GLC, GLE, V-Class, Vito and Sprinter
Model names help identify your request. Support depends on the year, generation and equipment; each vehicle is checked before an appointment is confirmed. Independent service, with no manufacturer affiliation claimed.

Your questions
Can every Mercedes key generation be replaced?
Support depends on the system and its security protections. Provide the year and model so feasibility can be confirmed before an appointment.
Should I throw away a key that no longer starts the car?
No. Keep it for assessment and describe any functions that still work. The fault should be identified before deciding on replacement.
