Visible Button Mercedes-Benz Key Protector Shell

This alloy key cover is made for Mercedes-Benz smart keys and built for everyday use. If your key is always in your pocket, bag, or car cup holder, it can get scratched fast. This cover helps keep your Mercedes key looking clean, while giving it a sharper, more premium finish.

Choose the style that fits you best: Crystal Gloss Key Shell for a clean shine, Carbon Fiber Tricolor Shell for a sporty look, Carbon Fiber Gunmetal for a darker aggressive finish, or AMG-Inspired Racing if you want that performance vibe. It’s an easy upgrade that makes your Mercedes key fob look better the moment you put it on.

The fit is made to match the key closely (1:1), with a strong alloy outer shell and a soft TPU layer inside. That inner layer adds grip and comfort and helps protect the buttons and edges without making the key feel bulky. Your Mercedes-Benz key fob stays easy to press and comfortable to hold.

It’s also designed so your key signal stays strong. Lock/unlock and keyless functions work normally, so you don’t need to remove the cover during daily use. Add your favorite Mercedes keychain or Mercedes-Benz keyring and you’re ready to go.

Features:

• Durable alloy shell: Helps protect against scratches, drops, and everyday wear.
• Soft TPU inner layer (360° coverage): Adds shock protection, better grip, and keeps button press feel comfortable.
• Visible button cutouts: Buttons stay clear and easy to press, with no stiffness.
• No signal interference: Designed to keep your Mercedes-Benz key signal responsive for daily use.
• Water & dust resistance: Helps protect from splashes, sweat, dust, and light moisture.
• Strong but lightweight: Metal protection without adding unnecessary weight.
