Transform Your 2017 Mercedes-Benz S-Class with OEM Options
Does your current car key feel a bit dated? This is a common sentiment among Mercedes-Benz S-Class owners. We recently completed an upgrade for a 2017 S-Class, transforming its smart key to the latest modern design. This isn't just about aesthetics; it's about ensuring perfect compatibility and enhancing the vehicle's premium feel.
Why Upgrade Your Mercedes-Benz S-Class Smart Key?
A smart key with an older design can detract from the overall luxury of a vehicle, especially a flagship sedan like the S-Class. Owners often want their key to reflect the same sophistication as the car itself. Upgrading to the newest oval-shaped key design offers more than just a cosmetic refresh; it elevates the car's prestige.
The Complexity of OEM Options Installation
It's crucial to understand that upgrading to a new-design smart key isn't a simple case swap. The internal security structures and communication protocols of older and newer keys are fundamentally different. This process requires precise data extraction, synchronization of the immobilizer system, and coding to the vehicle's modules. Any misstep in these intricate stages can lead to serious issues, such as the car failing to start. Professional expertise is essential for a safe and accurate installation of these OEM options.
OEM Options Installation Process:
- Vehicle Diagnosis and Data Backup: The process begins with a thorough diagnostic scan to safely back up the existing key's information.
- New Key Setup and Vehicle Matching: The new smart key is configured, and coding is performed to match it precisely with the S-Class's systems.
- Functionality Testing: A comprehensive test is conducted to ensure all functions operate flawlessly, including door unlocking, remote locking, trunk release, and ignition start.
This entire procedure typically takes about 3 to 4 hours to complete.
Post-Installation Benefits and Maintenance
After the upgrade, your new OEM smart key can be customized with various case colors, such as a sleek black or a refined white, offering a completely different aesthetic for your S-Class. Many owners report feeling that the new key finally matches the car's elegance. For display key models, regular charging is important. Frequent deep discharges can shorten battery life, so using a charger with the correct specifications and topping it up periodically is recommended. With proper care, you can expect the upgraded key to last approximately 3 to 5 years.
The cost for this type of factory upgrade retrofit typically ranges from 300,000 to 600,000 Korean Won (approximately $220-$440 USD, depending on exchange rates). For the most accurate pricing, a consultation based on your specific vehicle and chosen key design is necessary.
