No digital key icon in app
The installed app on my android does not have a digital key icon. Going to MBUX>open/close/>digital key>setup starts and when I put my phone in the cradle it asks for a 8 digit code which I dont have and then fails. Is it possible the build doesn't have the option?

AFAIK the digital key does NOT work with Android devices.

Mr. ua549 is correct unless MB or Android software makes a change to allow for digital keys. Until then, know that the iPhone digital key works very well and I hope they find a way for it to work with Android-run phones as well. I find the digital key to be very convenient and I like using it.

Android apps will not work across all device platforms. That is the issue. To work the app would have to account for every platform. There are over 24,000 distinct Android devices produced by 1,300 different brands. produced by nearly 1,300 brands

That's not a requirement for Android apps. It may be the reason MB decided not to add support for Android, but there are apps that do not work on all Android phones. An example are tap to pay apps such as Google wallet that require NFC to work. Not all Android phones have NFC yet the apps exist and can even be installed, but only work fully on phones with NFC. Another example are the fitness apps that track steps. Not all Android phones have an accelerometer to support step counting without external hardware.

Reasons for focusing on Apple's technology
- Existing Partnership:
Mercedes-Benz has a direct partnership with Apple, which facilitates the integration of their Digital Key into Apple Wallet on iPhones. - User Experience:
The integration with Apple Wallet allows for a seamless experience for iPhone users, who can access their car key with their device's passcode, Face ID, or Touch ID.
- Control over Software:
Mercedes-Benz, like some other automakers such as General Motors, prefers to retain greater control over the vehicle's software and user experience, rather than making it dependent on external mobile platforms. - Reduced Dependency on External Systems:
By not adopting a full Android solution for the digital key, Mercedes-Benz can avoid being solely reliant on Android's development and potentially create a more proprietary and integrated system. - Liability Concerns:
Automakers often worry about liability issues if a third-party system, like Android's, fails or causes a bug that affects the vehicle's critical functions. - Strategic Decision for a Comprehensive Experience:
Mercedes-Benz aims to provide a more complete and consistent software experience within the vehicle's digital ecosystem, which requires deeper control than what a third-party integration might offer.

After 1 hour on the phone with MB twice, here is the story they came up with. After escalating the case they came back and said that the Samsung Galaxy S22 Ultra was compatible with the digital key. Another hour and further escalation. They an email saying the reason it isn't working is because it doesn't work with a 2024 E450. But I have a 2025 E450. Their response but the car was built in 2024. Since delivery was in May of 2025, I doubt that is the case. MB is very nice on the phone but seems like MB support is on a downward slide. I will bring it up with the dealer.
