Spare Mercedes-Benz Key vs All Keys Lost
Whether one working Mercedes-Benz key remains has a major effect on the procedure, parts and cost.
If one Mercedes-Benz key still works
- The working key helps identify the correct electronics
- The vehicle’s normal operation can be confirmed
- A spare can often be added more efficiently
- The new key can be tested against a known-good key
- You avoid a more involved all-keys-lost recovery
This is normally the best time to arrange a spare Mercedes-Benz key.
