Key Service for 1998 Mercedes-Benz S 600
Our Mercedes-Benz S-Class and CL (W140 / C140, 1997–1999) key replacement service programs a new key to your vehicle's immobilizer, so you regain reliable locking, unlocking and starting. We can also block missing keys for security. The service is mail-in: you send us the car's key control module and keys, and we return them with your new key programmed. That can save you a tow and a dealer visit. All keys lost? We can still help. Please contact us with your VIN before you order.
Common reasons you may need a replacement key:
- Lost, stolen or physically damaged key.
- The car doesn't start with the key.
- Remote buttons don't work, or only at very short range, even with a fresh battery.
- Worn or bent blade, making the key unreliable.
