Quick answer
No, a well-made custom keychain like the Billetworkz Rexzilla Keychain won't damage your key fob. The real risk isn't the keychain itself but excessive weight or sharp edges — neither of which apply to these lightweight, carefully finished designs.
Why the myth persists
Many drivers worry that adding a metal keychain could scratch the fob's plastic housing or interfere with the internal electronics. In practice, the fob's shell is designed to withstand daily wear, and a keychain attaches to the ring, not the fob body. Scratches come from keys and coins, not the keychain.
What actually matters for fob safety
The main concern is weight. A heavy keychain can strain the fob's attachment point over time, especially if you toss your keys into a bag or pocket. Lightweight options like the Billetworkz keychains — made with the same attention to detail as their shift knobs — keep the load minimal. Another factor is material finish: rough edges could abrade the fob. These keychains are built to be smooth and durable, reducing that risk.
The trade-off of B-stock items
B-Stock items are final sale and may have minor cosmetic imperfections. However, these imperfections are only visual — they don't affect the keychain's function or safety. You still get the same lightweight, durable construction that won't harm your fob.
Myth vs. Reality: Keychain & Key Fob Safety
- Myth: A custom keychain will scratch your key fob: Reality: The keychain attaches to the ring, not the fob. Scratches typically come from keys or other objects, not the keychain itself.
- Myth: Heavy keychains damage fob internals: Reality: Excessive weight can stress the attachment point, but lightweight options like Billetworkz keychains minimize that risk. Keep your keychain light and your fob safe. Check the weight of your keychain. If it feels heavy, consider a lighter alternative.
- Myth: Metal keychains have sharp edges that cut into the fob: Reality: Quality keychains are finished smooth. Billetworkz keychains are made with the same attention to detail as their shift knobs, ensuring no rough edges. Inspect your keychain for burrs or sharp spots. If you find any, file them down or choose a different keychain.
