Mercedes-Benz Key Replacement Service

Ordering a New Key at Mercedes-Benz of Austin

Keys promote safety by securing access to those with the key. Keyless fobs introduce new security technologies that provide exclusive access to those holding the key with e-security features. You might have noticed that your Mercedes-Benz engine will not start unless you have the keyless fob inside the cabin. Ordering a new Mercedes-Benz key includes similar security features to ensure nobody else can get a key. We understand that ordering a new key might seem impossible at first, given the security measures involved, so we published a page dedicated to ordering a new key at Mercedes-Benz of Austin. Review how to order a new key as a registered owner, on behalf of an individual, or on behalf of a company. Gather the pertinent documents and bring them to the parts department during open hours to order a new key. Consider getting a battery replacement service if you have your key, but it no longer seems to function correctly. Contact us regarding your key and its requirements to restore performance at Mercedes-Benz of Austin.
