CH751 keys are commonly used on exterior storage and utility compartments on many RVs and trailers. You’ll also see that code on some cam locks used for truck caps, tool boxes, and general-purpose equipment cabinets. Compatibility isn’t universal, though—it depends on the lock core.

• Where to look: If the lock face is stamped “CH751,” a CH751 key is typically intended for it.
• What it’s not for: It’s generally not used for vehicle ignitions or main entry doors.
• Why it’s common: CH751 simplifies access to non-critical compartments from the factory.

If you’re unsure, compare your lock’s code and keyway, or ask a locksmith. You can shop pre-cut CH751 replacements and lock upgrades on Walmart.com.

Compatibility is determined by the lock’s code and keyway, not just the key’s name. CH751 keys typically fit cam-style locks used on RV baggage doors, trailer compartments, truck toppers, and some tool or utility boxes—when those locks are stamped “CH751.”

• Check the lock face: Look for “CH751” engraved near the keyhole.
• Check your key: Existing keys or manuals often list the code.
• Visual match: Compare the keyway shape with product photos before you buy.

Because manufacturers may change components, there can be exceptions. When in doubt, bring your current key to a locksmith for confirmation. For quick replacements, you can find CH751-coded keys and compatible locks on Walmart.com, but verify your code first to avoid returns.

“CH751” is a key code that refers to a specific cut pattern and lock code, not a single universal blank. If you’re duplicating a key, you’ll need a blank that matches the lock’s keyway profile and then cut it to the CH751 pattern.

• Fastest option: Buy a pre-cut CH751 replacement, which is ready to use if your lock is marked “CH751.”
• Cutting a duplicate: Bring an existing key or the code to a locksmith so they can select the correct blank and cut it properly.
• Confirm first: Since keyways vary, confirming the lock code helps avoid mismatches.

Walmart.com carries pre-cut CH751 keys and lock sets; checking product photos and details can help you match what you need.

There isn’t one key that opens every camper, but many RV and trailer compartment locks have historically used shared codes—CH751 being one of the most common. That means owners with CH751-coded locks can often use the same key for exterior storage, fuel doors, or utility panels across similar locks.

• What it usually doesn’t open: Main entry doors and ignitions are typically on different, unique keys.
• Why it exists: Shared codes make manufacturing and basic access easier for non-critical areas.
• Security tip: If you want more unique access, consider replacing cam locks with different codes.

Before purchasing keys, verify the code stamped on your lock. You can shop alternative lock codes and replacements on Walmart.com.

Start by inspecting the lock and any existing keys. Many cam locks have the code stamped on the face or the flat near the keyhole, and “CH751” will be clearly visible if that’s the code.

1. Check the lock face: Clean around the cylinder and look for “CH751.”
2. Check your keys/manual: The code may be etched on the key head or printed in your RV paperwork.
3. Compare photos: Match your lock and keyway to product images of CH751 keys before buying.
4. Ask a pro: A locksmith can confirm the code if markings are missing.

If the lock isn’t marked or you’re unsure, proceed cautiously—removing hardware isn’t always necessary. Once confirmed, you can order CH751 replacements or consider lock upgrades at Walmart.com.
