Best Spare Tire Lock for Trailers, SUVs and Jeeps

#1 · Best Overall

1. Trimax TNL740 Nut Lock

• dimensions: 5.08 x 8.38 x 13.72 in
• Weight: 3.52 oz
• Material: Alloy Steel

Best for: Side-mount and propane users.

Why it ranks #1: Its listed universal fit for side-mounted spare tires suits a broad set of vehicles, and alloy-steel construction provides a direct, easy-install locking solution.

Universal fit for side-mounted spare tires is the defining feature of the Trimax TNL740, giving owners a straightforward way to secure a spare without a vehicle-specific lock. The product is also listed for propane-tank security, extending its use beyond a trailer or SUV tire setup.

Its side-mount compatibility makes this a candidate for owners whose spare sits on the side rather than in a vehicle-specific carrier. Trimax also lists propane tanks as a use, so the same lock can serve a second security task when needed. The stated easy-install approach supports a simple setup, while the alloy-steel construction provides the lock body material. The listing does not specify a cable or a fit range for other mounting arrangements.

Skip it if you have a vertical carrier or need a frame-wrapping cable; Trimax ST30 secures a tire and bracket with a cable.

Choose the TNL740 if you need a side-mount spare lock and value the option of securing a propane tank with it. Its stated tire use is side-mounted spares, so it is not the match for every carrier style.

#2 · Best Dual-Point

2. Trimax ST30 Cable Lock

• dimensions: 2.3 x 8.8 x 11.5 in
• Material: Alloy Steel, Chrome, Stainless Steel

Best for: Frame-loop cable security.

Why it ranks #2: The 36-inch cable loops around the vehicle frame and is designed to secure both the spare tire and its bracket across several vehicle types.

A 36-inch welded cable that loops around the vehicle or trailer frame sets the Trimax ST30 apart, letting owners secure both the spare tire and its mounting bracket. Its stated applications span boat trailers, motorhomes, trucks, Jeeps, and vans, making it a flexible choice across several vehicle types.

The frame-loop cable provides an anchoring route beyond the spare itself, while the listing specifically says the lock secures both the tire and bracket. At 36 inches long and 12 mm thick, its stated dimensions help buyers assess the cable layout for their setup. A weather-proof cap protects the lock mechanism, a practical detail for exposed trailer or vehicle use. The cable approach requires a route around the frame.

Skip it if you want a compact lug-replacement lock for a vertical marine carrier; Heininger 6027 specifies that application and rim thickness.

The ST30 suits owners of trailers, motorhomes, trucks, Jeeps, or vans who want the spare and bracket tied to the frame. Choose it when your setup allows the 36-inch cable to loop around a secure frame section.

#3 · Best Chrome Finish

3. CURT 23562 Spare Tire Lock

• dimensions: 1 x 5 x 4 in
• Weight: 6.4 oz
• Material: Alloy Steel, Chrome

Best for: Chrome side-mount protection.

Why it ranks #3: This steel lock is specifically designed for side-mount spares, has a corrosion-resistant chrome-plated finish, and includes two keys.

A chrome-plated steel body gives the CURT 23562 a corrosion-resistant finish for securing a side-mounted spare tire outdoors. The lock is specifically made for that mounting style, and two included keys offer a backup access option for owners who do not want to rely on a single key.

The side-mount-specific format narrows the fit question to the intended carrier style, rather than a broad range of mounting systems. Steel construction supplies the lock body, while its chrome-plated finish is stated to resist corrosion from exposure to the elements. Two keys are included, allowing one to be kept as a spare. The product description focuses on vehicle side-mount spares, so it is less versatile than a cable lock listed for multiple vehicle types.

Skip it if you need one lock for a frame-loop cable setup or several vehicle types; Trimax ST30 lists trucks, trailers, Jeeps, vans, and more.

Pick the CURT 23562 for a side-mount spare when steel construction, a chrome-plated finish, and two keys suit your priorities. Its stated application is specific to side-mount tires, so carrier style matters.

#4 · Best Password Lock

4. HonesaLoc Nut Lock

• dimensions: 1.69 x 1.18 x 2.25 in
• Material: Metal

Best for: Password-lock side mounts.

Why it ranks #4: This steel, chrome-plated nut lock is listed for side-mounted spares and uses a password design rather than a key lock.

A password-style lock rather than a key lock is the HonesaLoc’s defining feature, giving side-mount spare owners a different access method while securing the tire nuts. The listing describes universal compatibility with side-mounted spares and cites steel construction with a chrome-plated surface.

The side-mount fit makes this a focused option for owners securing that style of spare, while the password lock provides the access method identified in the listing. Steel construction is described as strong, and the chrome-plated surface is specified as corrosion resistant, relevant for an outdoor vehicle accessory. Its compact listed dimensions—1.69 by 1.18 by 2.25 inches—may help when considering clearance around the nut. The product is also listed for vehicles and outdoor equipment.

Skip it if you prefer ignition-key access and own a compatible Jeep Wrangler; BOLT 7032301 opens with that vehicle's key.

Consider the HonesaLoc if you need a side-mount spare lock and prefer password access over a key. Its listed tire application is side-mounted spares, so owners with vertical carriers should consider another format.

#5

5. RITE-HITE Spare Tire Lock

• Weight: 0.27 g
• Material: die

Best for: Simple lug-nut installation.

Why it ranks #5: Its stated uses include spare tires on boat trailers, RVs, SUVs and cattle trailers, with a lock and key included and weather resistance listed.

Installation by removing one lug nut and fitting the lock and cover gives the RITE-HITE a direct way to secure a non-operating spare. The listing names boat trailers, RVs, SUVs, and cattle trailers as use cases, and describes installation and removal as easy.

The lug-nut replacement approach puts the lock directly at the spare’s mounting point: remove one lug nut, then install the lock and cover. That workflow is practical for a spare that remains mounted and is not being used for driving. Its listed applications include boat trailers, RVs, SUVs, and cattle trailers, while the weather-resistant designation supports exposed storage. The listing includes a lock and key but does not provide a rim-thickness range.

Skip it if you need an adjustable rim-thickness range for a vertical carrier; Heininger 6027 specifies a 1/4-to-7/8-inch rim range.

The RITE-HITE fits owners securing a non-operating spare on a boat trailer, RV, SUV, or cattle trailer who prefer a lug-nut installation. Its stated method requires access to a lug nut on the mounted spare.

#6 · Best Vertical Mount

6. Heininger 6027 Trailer Lock

• Weight: 9.6 oz

Best for: Vertical marine-carrier fit.

Why it ranks #6: It is made for marine, utility and RV vertical-mount spares, fitting rims 1/4 to 7/8 inch thick; it is not designed for truck or SUV spares.

An adjustable pin for rims from 1/4 to 7/8 inch thick makes the Heininger 6027 a specific fit option for vertical marine, utility, and RV spare carriers. Its flush locking design replaces a lug bolt, securing the spare directly to its carrier.

The adjustable pin diameter and stated 1/4-to-7/8-inch rim range help owners check whether their wheel thickness suits this lock before installation. The lock replaces one lug bolt, so it secures the wheel at the carrier rather than relying on a cable routed around the frame. Its flush design keeps the locking assembly close to the mounting point. The product is explicitly not for truck or SUV spare tires, and it will not work with welded spare lugs.

Skip it if you are securing a truck or SUV spare, or have welded lugs; CURT 23562 is specified for side-mount vehicle spares.

Choose the 6027 for a vertical marine, utility, or RV carrier when the rim thickness falls within its stated range. It is not suitable for truck or SUV spares, and welded lugs rule it out.

#7

7. BOLT 7032301 JL Lock

• dimensions: 2.75 x 5.75 x 5.13 in
• Weight: 16 oz
• Material: Stainless Steel

Best for: Jeep JL ignition-key access.

Why it ranks #7: This lock is designed for 2018-and-newer JL compatibility and uses the Jeep ignition key, with a stainless-steel pin replacing a lug nut.

The BOLT 7032301 opens with a compatible Jeep Wrangler ignition key, eliminating a separate spare-lock key for owners of a 2018-or-newer JL. Its stainless-steel pin replaces a lug nut, and an auto-return spring locks the mechanism when the key is removed.

Using the Jeep ignition key keeps spare-tire access tied to a key the owner already carries, rather than a separate lock key. The stainless-steel pin replaces one lug nut and fits most OEM and aftermarket alloy wheels, while the auto-return spring locks when the key comes out. A double-ball-bearing mechanism and plate-tumbler sidebar are listed to resist picking and bumping. BOLT locks permanently learn the first key used and cannot be reset.

Skip it if you have a 2007–2018 Wrangler JK; BOLT 5922986 is the listed model for that generation.

This lock suits 2018-and-newer JL Wrangler owners who want spare access keyed to their ignition key. It fits most OEM and aftermarket alloy wheels, but the first key used becomes permanent and cannot be changed.

8. BOLT 5922986 JK Lock

• dimensions: 11 x 7 x 6.5 in
• Weight: 16 oz
• Material: Stainless,Stainless Steel,Steel

Best for: Jeep Wrangler JK key match.

Why it ranks #8: For 2007–2018 Jeep Wrangler JKs, it replaces a 1/2-20 lug nut and opens with the vehicle's ignition key; check the stated wheel-well dimensions.

Keying the spare lock to a Jeep Wrangler ignition key makes the BOLT 5922986 a convenient fit for 2007–2018 JK owners who want to avoid carrying a separate key. Its stainless-steel pin replaces one 1/2-inch-20 lug nut and automatically locks when the key is removed.

The ignition-key match simplifies access for JK owners by consolidating the spare lock with the vehicle key. Its pin replaces one 1/2-inch-20 thread lug nut, and the listing says it fits most OEM and aftermarket alloy wheels. The auto-return spring locks the mechanism when the key is removed, while a six-plate tumbler sidebar is specified to resist picking and bumping. The description recommends a 1-to-1 1/8-inch lug-nut well for best results.

Skip it if you have a 2018-or-newer Wrangler JL; BOLT 7032301 is listed for that generation and also uses the ignition key.

Choose the 5922986 for a 2007–2018 Wrangler JK when ignition-key access and automatic relocking matter. It fits most OEM and aftermarket alloy wheels, with the stated lug-nut-well range relevant to best results.

#9

9. Mopar Spare Tire Lock

• Weight: 1 lb

Best for: Genuine Jeep Gladiator fit.

Why it ranks #9: This genuine Mopar lock is described for the Jeep Gladiator and includes a special key for lowering and raising the spare as needed.

A Mopar-exclusive key that lets owners lower and raise the spare is the defining convenience of this Jeep Gladiator spare-tire lock. The listing describes a key-lock mechanism and handheld control, pairing tire security with an access method intended for the vehicle’s spare-tire operation.

The key-lock mechanism secures the tire in place, while the listing’s Mopar-exclusive key is specifically described as allowing the spare to be lowered and raised as needed. That combination matters to owners who need security without giving up access for a tire change. Mopar identifies the product as a genuine spare-tire lock for the Jeep Gladiator, and the listed special feature is a key lock. The supplied information does not state a broader vehicle fit range.

Skip it if you drive a 2007–2018 Wrangler JK; BOLT 5922986 is specifically listed for that Jeep generation.

This Mopar lock suits Jeep Gladiator owners who want to secure the spare while retaining the described ability to lower and raise it. Its stated fit is Gladiator-specific, so other Jeep models need a different match.

#10

10. Toyota PT276-34071 Lock

• dimensions: 11 x 5.5 x 1.5 in
• Weight: 7.2 oz
• Material: Metal

Best for: Select Tacoma and Tundra owners.

Why it ranks #10: This OEM lock is specified for select Toyota Tacoma and Tundra models, so its narrow vehicle fit makes it less versatile than the higher-ranked options.

Genuine Toyota OEM status is the central draw of the PT276-34071, a spare tire lock listed for select Tacoma and Tundra models. It gives owners seeking a manufacturer accessory a vehicle-specific security option rather than an aftermarket product, with metal construction and a wheel-lock designation.

Toyota identifies this as an OEM accessory, which makes it relevant to owners seeking a manufacturer-branded part rather than an aftermarket lock. Its stated application is securing the spare on select Tacoma and Tundra models, so model-specific suitability is central to the choice. The metal construction and wheel-lock designation describe its basic form, while the listed dimensions are 11 by 5.5 by 1.5 inches. The supplied details do not name additional vehicle models.

Skip it if you own a Jeep Wrangler and want ignition-key access; BOLT 7032301 is listed for the JL and uses the Wrangler key.

Choose this Toyota accessory if you own a select Tacoma or Tundra and want an OEM spare-tire lock. Its stated application is limited to those Toyota model lines, so owners of other vehicles should look elsewhere.
