A Keyed-Different Alternative to the CH751 Fuel Cam Lock

If you have spent any time on iRV2, Forest River Forums, or the Good Sam boards, you have seen the warning: the CH751 key opens half the RV world. Storage bays, service panels, and a lot of budget “locking” fuel caps all share the same universal CH751 code. Someone can buy that key for a couple of dollars and walk down a row of rigs.

Why a CH751 fuel cam lock is not really a lock

A cam lock or locking cap keyed to CH751 looks like security, but the whole point of a lock is that not everyone has the key. When the key is universal, you have added the inconvenience of a lock with none of the protection. That is exactly the frustration RV owners post about after they realize their “locking” cap opens with the same key as their neighbor’s bay door.

What keyed-different actually means

Keyed different means your lock uses a key that is not shared across the product line — a stranger with a CH751 (or with a key from another RV Fuel Vault customer) cannot open it. That is the difference between a deterrent and a decoration.

The RV Fuel Vault: keyed-different by design

The RV Fuel Vault is a locking fuel door that secures your fuel fill without the CH751 problem:

• Keyed different from the universal CH751 — real, individual security.
• Keyed-alike multi-packs — buy two or three and they share one key, so you carry a single key for all your doors while still being different from everyone else.
• Anti-tamper security screws included — no simply unscrewing the door.
• Locks over your factory cap — the OEM cap and EVAP seal stay in place, so there is no check-engine light.
• Built from 3/16" High Impact Reinforced Material; installs in about 8–15 minutes.

What about drilling?

Yes, a determined thief with time and tools can defeat almost anything. But the real threat to RVers is opportunistic — the person with a universal key and thirty seconds. Being keyed different removes exactly that threat.
