At Keyless City, our Fobik Key Shells collection focuses on aftermarket replacement cases for Chrysler, Dodge, Jeep, VW, and Mercedes fob-keys used with embedded smart electronics. These cases aren't just housing—they’re high-quality replacements with correct button layouts, trim fit, and battery access built to match OEM specifications. Tough, precise, and priced for professionals, they’re your lifeline when a shell cracks or buttons fail—keeping your clients rolling and your reputation sharp.

Collection Overview 

This Fobik Key Shells collection includes two key shells tailored for popular vehicle families: Chrysler/Dodge/Jeep/VW 5-button IYZ‑C01C style, and Mercedes 4-button IYZ‑3312 type. Designed to house OEM circuits and batteries, these replacement cases give locksmiths the ability to restore remote function cleanly, no programming or electronics swaps required. Simply transfer internals and blade, snap them in, and you're back in business. Made with strong plastic construction, reliable button membranes, and exact fit, these shells restore functionality and looks at a fraction of OEM cost.

Chrysler/Dodge/Jeep/VW 5‑Button Shell (IYZ‑C01C)

Our 5‑button Fobik shell fits smart key-equipped Chrysler, Dodge, Jeep, and VW vehicles from 2008 to 2019—matching the IYZ‑C01C protocol. Features include correct lock/unlock, trunk, panic, and remote start button placement. The aftermarket housing supports battery access, sturdy internal latches for circuit board retention, and precise key blade fitment. It’s a cost-effective choice for re-shelling jobs where the electronics are solid but the case is damaged. Clean switch behavior, rigid structure, and easy blade transfer make it a reliable solution for mobile or shop-based key repair.

Mercedes 4‑Button Shell (IYZ‑3312) 

For Mercedes owners, our 4‑button Fobik shell is built to fit the common IYZ‑3312 smart key case (1997–2014). It supports lock, unlock, trunk, and panic functions with correct silicone pad layout. The aftermarket shell features reinforced spots for internal PCB mounts and a snug fit around the existing Mercedes blade. It's an affordable OEM-alternative when factory shells run much higher. Swap your customer’s electronics and blade into this case and you’ve got a factory-quality finish—no remote rebuild needed. Quality plastic, clean button feel, and accurate cutouts ensure a solid repair every time.

Why This Collection Stands Out

What sets these Fobik key shells apart is OEM-level fit at aftermarket prices. The precise button remapping and shell tolerances make electronics transfers seamless—no jury-rigging or gaps. Each aftermarket case includes correct battery compartments, PCB retention features, and blade slots tailored to vehicle specs. Replacement shells eliminate the hassle of warped buttons or broken seams, restore premium feel, and keep your clients happy. With only two SKUs but broad vehicle coverage, these shells cut stock complexity and give professionals quick go-to assets for Chrysler, Dodge, Jeep, VW, and Mercedes key repairs.
