Every week, someone asks us: "Will a leather cover block my key fob signal?" It's a fair question — nobody wants to wrap their key in something that stops it from working. The short answer is no. Leather doesn't block your fob's signal. But let's explain why, and what actually can weaken it.
📻 How Your Key Fob Talks to Your Car
Your key fob communicates with your car using low-frequency radio waves — the same basic technology as a garage door opener. When you press a button (or walk up with keyless entry), the fob broadcasts a short encrypted radio signal, and your car listens for it. For that to fail, something has to physically shield or absorb those radio waves between the fob and the car.
🧵 Why Leather Doesn't Block the Signal
Radio waves pass through non-metallic materials easily — that's why your fob works from inside your pocket, your bag, or your jacket. Leather is just animal hide that's been tanned and finished. It contains no metal, no conductive mesh, nothing that interacts with radio frequencies. A leather cover is, to your fob's signal, essentially invisible — like wrapping your phone in a cloth napkin and expecting the Wi-Fi to drop.
⚠️ What Actually Weakens Your Signal
If your range has gotten worse, the cover isn't the culprit. The usual suspects are:
- A dying battery — the number one cause of weak range, by far.
- Metal cases — aluminum or metal-shell covers can act like a partial shield.
- Faraday pouches — these are designed to block signals on purpose (great against relay theft, terrible for daily use).
- Interference — parking near strong radio sources can drown out the fob's signal.
✅ Our Position
We make our covers from full-grain, vegetable-tanned leather with zero metal components — no magnetic clasps, no metal frames. Your fob will work exactly as it did before, just better protected. If you ever notice reduced range, check the battery first. It's almost always the battery.
