Car Key Case Replacement in Longbridge

What Is a Key Case for Car Keys?

A key case — also called a fob shell — is the plastic housing your key's electronics live in. The transponder chip, circuit board, battery and blade slot stay exactly as they are; only the outer casing is swapped. Because your original electronics keep their coding, there's no reprogramming involved.

Replacement cases come as plain shells, flip-key cases with a new hinge mechanism, and smart-key shells. We match the case style to your fob so the buttons line up properly and the blade folds away cleanly.

When a Replacement Case Is the Right Fix

• ✓Cracked or split shell — the key works fine but the casing is falling apart.
• ✓Crumbling buttons — the rubber pads are worn through but the switches underneath work.
• ✓Broken flip mechanism — the blade won't stay in or out, but the electronics are fine.
• ✓Cosmetic damage — the key works perfectly, it just looks rough.

Key Fob Shell Replacement: How It Works

We open your existing fob, transfer the circuit board, transponder chip and battery into the new case, and fit your existing blade (or cut a fresh one if the old blade is worn). Buttons are tested before and after the move, so the finished key works exactly as it did — it just looks and feels new.

The whole job is done at your car in one visit. Because nothing electronic changes, your key starts the car and operates the locks exactly as before — no coding, no pairing, no fuss.

Cheaper Than a Full New Key

A case replacement is genuinely the budget option: you're paying for the shell and the careful transfer work, not for new electronics or programming. If your fob's internals are healthy, there's no reason to pay for a whole new key.

If we open the fob and find the electronics are damaged too, we'll show you and explain the options — which may be a repair or a full replacement. The price you approve on WhatsApp is always confirmed before we start, whichever route you take.
