Mercedes-Benz E-Class oval smart key conversion: Starts around 100,000 KRW. Upgrades key design while retaining all functions.
Upgrade Your Mercedes-Benz E-Class Smart Key
Many Mercedes-Benz owners love their vehicles but feel the smart key design doesn't quite match the car's luxury, especially with older square-shaped keys found on models like the 2018 E-Class. If you're looking to modernize your key fob to the sleeker, latest oval design, this upgrade offers a significant aesthetic improvement. This review covers the process, potential costs, and what to expect from a factory option retrofit.
The Latest Oval Smart Key Conversion Process
Transforming your existing 3-button square Mercedes-Benz smart key into the modern 5-button oval version is a specialized process. It involves transferring your current key's internal components into the new housing, ensuring all your car's functions remain intact while updating the exterior. The conversion typically includes two main parts: the aesthetic upgrade to the oval design and the cutting of a new metal emergency key to fit inside.
Installation process:
- Careful disassembly of the old smart key.
- Transferring the internal electronics and transponder chip to the new oval key housing.
- Programming and testing of all functions (locking, unlocking, trunk release, ignition).
- Cutting of the new metal emergency key to match the vehicle's locks.
- Final assembly and handover.
After the conversion, you'll retain all original functions like door locking, trunk opening, and starting the car. The new key offers improved ergonomics, a more premium feel, and a refined button operation, enhancing the overall user experience. In Korea, this type of conversion is often completed within 1 to 2 days, depending on the specific workshop and any additional requests.
Durability and Maintenance of Your New Smart Key
The durability of the converted smart key is generally comparable to a new OEM key. The external housing is designed for daily use, and the internal components are your original, functioning parts. Maintenance primarily involves ensuring the battery is replaced periodically, just like any smart key. While the new housing is robust, treating it with care, as you would any valuable item, will ensure its longevity. The metal emergency key is also built for durability, providing a reliable backup.
This upgrade is particularly recommended for owners who feel their current smart key design is outdated or doesn't reflect the premium status of their Mercedes-Benz E-Class. It's a way to enhance the perceived value and modern feel of your vehicle without altering its core functionality. The cost for this conversion in Korea starts around 100,000 KRW (approximately under $100 USD, though actual US pricing may vary significantly). This price typically includes the key housing and the metal key cutting service.
