Camco 44340 5/8-Inch Keyed Baggage Cam Lock | 2 Keys

A baggage compartment lock is one of those parts you don't think about until the key snaps off or the cylinder seizes up on a cold morning. The Camco 44340 is the straightforward fix. It's a keyed cam lock built for the exterior storage doors on RVs, campers, and trailers, and it works just as well on a boat's deck storage locker or a dockside storage box. You get the lock cylinder, two keys, and both cams you'll need to make it work on most doors.

The one number that matters most here is the cylinder length. This is the 5/8 inch version. Camco also makes a 7/8 inch cam lock, and the two aren't interchangeable, so measure your existing lock or the thickness of your door before you order. If your old lock is already out, measure the barrel from behind the door face to where the cam sits. Getting the length right is the difference between a lock that sits flush and turns freely and one that binds or won't seat at all.

This is a keyed lock, not a thumb-turn. That matters. A keyless twist lock keeps a door shut, but it doesn't keep anyone out. The 44340 needs a key to open, so it gives you actual security for the gear you store out of sight, tools, hoses, life jackets, shore power cords, whatever lives in that compartment. Two keys come in the package, so you've got a spare from day one.

Camco includes two cams with this lock, and that's more useful than it sounds. There's a 5/8 inch offset cam and a straight cam. The offset cam has a slight bend built into it, which lets it reach around a frame lip or bridge a small gap between the lock body and the strike. The straight cam is flat and works when the catch sits directly behind the door. You pick whichever one matches how your door and frame line up, bolt it on, and you're set. Most baggage doors take the offset, but having both in the bag means you're not making a second trip for the wrong part.

Think about where it goes. On a travel trailer, it's the exterior pass-through and utility bay doors. On a fifth wheel, the front storage. On a boat, it's the anchor locker lid, a cockpit storage hatch, or a console door where you keep electronics and valuables. Anywhere you've got a thin door or panel and want a keyed latch behind it, a 5/8 inch cam lock like this one is the standard answer.

Installation is about as simple as it gets. Pop the old cylinder out, drop the 44340 into the same hole, choose your cam, and snug down the retaining nut. No wiring, no drilling if you're replacing a same-size lock. Ten minutes with a screwdriver and you're locked up again. If you're upgrading from a keyless latch to this keyed version, just confirm the hole diameter matches before you start.

One small tip from us. Tag those two keys and stash the spare somewhere off the boat or rig, a keychain at home or in the tow vehicle. Compartment lock keys are small and easy to lose, and having the backup somewhere separate saves you from drilling the lock out later.

We stock this because it solves a real problem for boaters and RVers alike. Salt air and road grime are hard on cheap locks, and a compartment lock that won't turn is a genuine headache when you're loading up to head out. The 44340 is an honest, inexpensive replacement from a brand that's been building RV and marine hardware since 1966. Keep one in the spares box. When a lock finally gives up, you'll be glad it's already on the shelf.
