The best horse trailer door lock depends on the door’s cutout size, thickness, hinge direction, and lock style. The Siasky replacement is designed for horse trailers and specified lock-hole dimensions; the Kohree is a zinc-alloy option for buyers prioritizing material strength. For a stainless steel paddle latch, consider WINOMO, while the CAMJOKE models suit buyers whose door measurements and handing match their listed requirements. Confirm fit before ordering: these products have different designs and stated specifications.

Siasky RV Door Lock Replacement
Best for: Horse-trailer owners replacing an entry latch with a matching 3.63 × 2.71-inch lock hole. The listing specifically names horse trailers, cargo haulers, travel trailers, and campers as intended uses.
The lock is made from zinc alloy and includes one lock with four alike keys. The product description also says the keys support double extraction. Its material is described as corrosion-resistant, hard, scratch-resistant, and oxidation-resistant.
Why it was selected: It is the most directly targeted option in this group for horse-trailer entry doors, and the listing provides a cutout measurement to compare with an existing lock. Limitation: Confirm your door’s opening matches the stated dimensions; the supplied information does not specify door thickness or hinge direction.
WINOMO Stainless Steel Paddle Latch
Best for: Buyers seeking a stainless steel, flush-mount paddle latch for a trailer, toolbox, truck door, or similar compartment. The listing describes a heavy-duty paddle mechanism and a mirror-polished finish intended to resist rust and wear.
Why it was selected: Stainless steel construction and a paddle-style design make it a distinct alternative to the zinc-alloy RV entry locks. It may suit a horse trailer compartment or door where this latch style and installation are appropriate.
Limitation: The supplied product details do not give cutout dimensions, door-thickness limits, or specific horse-trailer entry-door fit. Check the installation requirements and intended use before choosing it for a main entry door.
Kohree Zinc-Alloy RV Door Lock
Best for: Buyers who want a replacement RV door lock made from 100% zinc alloy. The listing describes a thickened solid base, oxidation treatment, wear resistance, and an IPX3 waterproof rating.
Why it was selected: Its material and construction details make it useful for shoppers comparing zinc-alloy locks for outdoor trailer use. The product includes a paddle deadbolt and is described as having a smooth surface and a durable design.
Limitation: The supplied details do not state the cutout dimensions, door thickness, or hinge direction. Measure the existing opening and verify fit rather than assuming it matches a particular horse-trailer door.
CAMJOKE Upgraded RV Door Lock
Best for: Buyers with a right-hinged door, a 2.75-inch-wide by 3.75-inch-high cutout, and a door thickness of 1.25 to 1.5 inches. The lock includes four alike keys, a deadbolt, and inside-and-outside operation.
The listing describes a self-closing bolt designed to reduce impact on the door frame and a mechanism intended to prevent finger pinching. It also identifies a back-locking function and a zinc-alloy body.
Why it was selected: The stated measurements and operating features help buyers compare it with a specific existing door setup. Limitation: It fits right-handed doors only and is listed as not suitable for glass doors or Class A and Class C RVs. Verify whether your trailer door matches its requirements.
CAMJOKE RV Deadbolt Lock With Four Keys
Best for: Owners of right-hinged trailer or camper doors with a 3.75-inch-tall by 2.75-inch-wide cutout and 1.25-to-1.5-inch door thickness. The package includes one lock, four keys, instructions, and screws in various lengths.
The listing describes a tamper-proof cylinder with unique key codes, plus zinc-alloy and plastic construction. It also states that the surface is UV-resistant and IP66 waterproof.
Why it was selected: It provides clear fit specifications and key details for comparing against an existing lock. Limitation: The listing excludes left-hinged doors, glass doors, and Class A or Class C RVs. Do not assume it fits without checking your door measurements.
Buying Guide: How to Choose a Horse Trailer Door Lock
Which measurements should you check?
Measure the existing lock opening from edge to edge, then check the door thickness and hinge direction. Compare those figures with the product listing. Even locks described for RVs or trailers can have different cutout dimensions, so a similar appearance does not establish fit.
Should you choose a paddle latch or a deadbolt lock?
A paddle latch may suit a flush-mount compartment or a door designed for that mechanism. An RV-style replacement with a paddle deadbolt may be better when you need the listed entry-lock functions. Match the mechanism to the existing installation and intended door use.
Which material details matter?
Compare the listed construction rather than relying on broad claims of durability. The products here include zinc-alloy options and a stainless steel paddle latch. Some listings also specify surface treatments or water-resistance ratings. Those details can help narrow choices, but they do not replace checking fit.
How many keys are included?
Several options include four keys, but keying details differ. Siasky and one CAMJOKE listing describe four alike keys; the other CAMJOKE listing describes keys coded to the lock. Check the exact product details if matching keys or keeping spare keys is important.
Frequently Asked Questions
Will any RV door lock fit a horse trailer?
No. Fit depends on the cutout size, door thickness, hinge direction, and lock design. Compare your measurements with the specific listing before ordering.
What is the most directly specified option for horse trailers?
The Siasky listing names horse trailers and states a 3.63 × 2.71-inch lock-hole size. Confirm that your existing opening matches.
Can I use a compartment paddle latch as the main door lock?
Not necessarily. The WINOMO listing names several uses, including toolboxes and trailer doors, but the supplied details do not specify horse-trailer entry-door dimensions. Verify the intended installation and fit.
Do these products include keys?
The listed Siasky and CAMJOKE models include four keys. Check each product’s package details, since keying and included hardware can vary.
Do the CAMJOKE locks fit left-hinged doors?
No. Both CAMJOKE listings specify right-hinged doors. Choose another option or confirm a different product’s handing if your door hinges are on the left.
