Silicon Smart Key Case – Protective Key Fob Cover For Smart Fortwo Forfour

The Smart Fortwo was designed around a single, clever idea: that a car for the city should think like a city. Compact where it needs to be, efficient where it counts, and unbothered by everything the urban environment throws at it.

Your Smart key fob should work the same way. This Silicone Smart Key Case gives your remote the same no-nonsense protection — a slim, flexible cover that resists scratches, absorbs drops, and adds grip to your key without adding weight, without complication, and without changing how anything works.

Designed for Urban Daily Use

City keys take more abuse than any other. They go in and out of pockets dozens of times a day, share space with transit cards and loose change, get tossed on café tables and office desks, and occasionally hit cobblestones at speed.

The food-grade silicone shell absorbs every minor impact before it reaches the original Smart key fob casing. No cracked plastic from pavement drops. No scratches from pocket friction. The honeycomb-textured surface adds grip so the key is easier to catch, easier to hold, and far less likely to slip in the first place.

Dust-resistant and easy to clean — a quick wipe with soap and water is all it takes.

Zero Interference with How Your Smart Key Works

• All buttons fully accessible — lock, unlock, and boot release respond with a clean press through the silicone
• Keyless entry passes through the cover without any signal loss
• Push-to-start and proximity detection work exactly as normal
• Emergency blade remains fully accessible at all times
• RF-transparent silicone — zero interference with any Smart key function

Slim. Light. No Added Bulk.

The Smart Fortwo exists because unnecessary bulk was eliminated. This key case follows the same logic. The protective shell adds less than 2mm to the profile of your Smart key fob — it stays slim in the pocket, clips and card holders, and the smallest bags. The silicone stays pliable in winter cold and holds its shape in summer heat.

Fitting takes seconds. Removal takes seconds. No tools, no adhesive, no permanent modification to your original key.

Available in Multiple Colours

Your Smart doesn't have to be anonymous — and neither does your key. Available in several colours including clean matte black, white, and accent tones that work with Smart's bold two-tone exterior palette. The soft-touch finish adds a tactile quality over bare plastic that makes the key noticeably nicer to handle every day.

Why Choose This Silicone Smart Key Case?

Frequently Asked Questions

How do I know which type fits my Smart key? Type A covers all Fortwo and Forfour models from 2007 to 2019 (451 and 453 generations). Type B covers the EQ line from 2020 onwards. Compare your fob shape to the product images — if still unsure, send us a photo and we'll confirm.

Will the case interfere with my Smart EQ's proximity entry? No. Silicone is fully RF-transparent. Proximity detection, keyless entry, and push-to-start all function normally through the cover with zero signal loss.

How do I access the battery or emergency blade? Simply peel the silicone case off — it takes a few seconds and leaves the original key completely untouched. Slide it back on when you're done.

Will it yellow or crack over time? High-grade silicone resists UV exposure, extreme temperatures, and everyday wear. It will not discolour or lose its shape even in direct sunlight.

Every order includes Free Shipping and is backed by our 1-Year Warranty.
