Additional key /add a key for 1990-1997 One Button Mercedes flip key

Purchasers of this item or service acknowledge that it requires mailing their existing, fully functional key to the address listed at the bottom of this webpage. Upon receipt, we will create a new key using only brand-new components—no refurbished parts.

Before the new key can be used, it must be synced with the vehicle. For certain vehicles, performing this synchronization before the first use is critical. Please contact us at the phone number provided at the bottom of this page so we can guide you through the synchronization process.

In most cases, the procedure involves inserting the new key into the ignition, turning the ignition to the “ON” position (without starting the engine), waiting approximately 10 seconds, and then removing the key.
