Best Small Safe For Car: Compare 10 Portable Lockboxes

#1 · Best Overall

1. Grimtron Portable Electronic Safe

• Dimensions: 11.02"D x 7"W x 1.85"H
• Weight: 3.7 lb
• Capacity: 0.06 cubic feet
• Material: Alloy Steel

Best for: Low-light keypad access.

Why it ranks #1: Its 11.02-by-7-by-1.85-inch case includes a security cable, backlit keypad, backup keys and USB-C emergency power for battery trouble.

A backlit keypad makes the Grimtron VT1136 easier to operate in dim vehicle interiors, while a security cable anchors the box to a fixed point. Its three-to-eight-digit code, backup keys, and USB-C emergency power offer several ways to regain access to stored contents.

At 11.02 by 7 by 1.85 inches, the slim alloy-steel case can fit in a vehicle storage spot while its included cable provides a way to tether it. The keypad accepts a personal three-to-eight-digit code and is backlit for low-light entry; backup keys provide another access method. If batteries run out, USB-C emergency power can temporarily power the keypad from a power bank or vehicle source. Silent mode is also listed as a feature.

Skip it if you prefer fingerprint entry over a keypad; the HISHARK GS301 lists biometric access, keypad, and backup key.

This suits drivers seeking a cable-secured handgun safe with keypad entry, backup keys, and an emergency power option. The 1.85-inch height supports a slim placement, but access still depends on the listed keypad or key methods.

#2 · Biometric Access

2. HISHARK Biometric Safe

• Dimensions: 11.4"D x 7.2"W x 2.57"H
• Weight: 4.3 lb
• Material: Alloy Steel

Best for: Fingerprint quick-access storage.

Why it ranks #2: The 11.4-by-7.2-by-2.57-inch safe offers fingerprint, keypad and key access, plus a steel cable for anchoring in a vehicle.

The HISHARK GS301 lists fingerprint unlocking in no more than 0.1 seconds, with storage for up to 100 fingerprints. That gives multiple authorized users a rapid biometric entry option, backed by a keypad and mechanical keys for alternate access in a car or bedside setup.

Its 11.4-by-7.2-by-2.57-inch alloy-steel case includes a steel cable for tethering and a form cushion for the interior. The fingerprint reader supports up to 100 stored prints, so multiple users can be registered, while the keypad and two mechanical keys provide additional listed unlocking methods. The rechargeable design is identified in the title, and the combination of portable dimensions and included cable supports moving the safe between a vehicle and bedside use.

Skip it if you want a lighter keyed box with a low profile; the Younion YSP-6K weighs 2.6 pounds and is 1.81 inches high.

This fits drivers who prioritize quick fingerprint access and need to register multiple users, with keypad and key alternatives available. Its 2.57-inch height and 4.3-pound weight matter when choosing a vehicle storage location.

#3 · Combination Lock

3. Dalmbox Compact Handgun Safe

• Dimensions: 9.4"D x 6.4"W x 1.8"H
• Capacity: 2.7 lb
• Material: Carbon Steel

Best for: Simple combination car storage.

Why it ranks #3: Its 9.4-by-6.4-by-1.8-inch profile and three-digit combination suit compact storage; a cable is included for securing the box.

A three-digit combination lock gives the Dalmbox DL-QX-CL keyless entry in a compact 9.4-by-6.4-by-1.8-inch case. That slim format supports placement in a car, drawer, or luggage, while the included cable offers a way to secure the box to a fixed point.

The listed interior measures 9.1 by 6.1 by 0.9 inches, with room described for most compact and subcompact handguns as well as magazines, passports, cash, and jewelry. The three-digit combination avoids relying on a key for routine opening, and the included cable supports tethering in a vehicle. Dalmbox also lists a key-lock version, but this model’s feature description identifies the combination lock. A manual and four-step setup information support initial use.

Skip it if you need a longer user-set code and backlit buttons; the Grimtron VT1136 lists both features.

This is a practical fit for drivers who want a compact combination box for a compact handgun or small valuables. Its cable supports anchoring, though its 0.9-inch interior height constrains what can lie inside.

#4 · Keyed Steel Box

4. Younion Portable Pistol Safe

• Dimensions: 9.69"D x 6.5"W x 1.81"H
• Weight: 2.6 lb
• Capacity: 3.3 lb
• Material: Alloy Steel

Best for: Keyed under-seat storage.

Why it ranks #4: This 9.69-by-6.5-by-1.81-inch alloy-steel lockbox includes two keys and a heavy steel cable for travel or vehicle use.

A 16-gauge steel housing gives the Younion YSP-6K a substantial metal shell in a slim, 1.81-inch-high profile. Its included heavy steel cable supports securing the box to a fixture, making it a compact keyed option for a vehicle or travel storage setup.

The 9.69-by-6.5-inch exterior and low profile are suited to concealed placement under a car seat, as described by the product, while the steel cable can tether it to a fixture. A keyed locking system comes with two keys, so there is no combination to enter. The listing describes use for a pistol as well as cash, medicine, passports, and jewelry. Its 2.6-pound weight and 3.3-pound stated capacity help define what to carry in the box.

Skip it if you want a combination rather than keyed access; the Dalmbox DL-QX-CL uses a three-digit combination lock.

Pick this for a low-profile, keyed box to tether under a seat or use while traveling. It accommodates a pistol and small valuables, but the key-based lock makes key control part of everyday access.

#5 · Lightweight Option

5. SEPOX Steel Case Lock Box

• Dimensions: 5.5"D x 7.87"W x 2"H
• Weight: 1.4 lb
• Capacity: 41 cubic in
• Material: Alloy Steel

Best for: Lightweight travel combination box.

Why it ranks #5: At 1.4 pounds and 8.1-by-5.7-by-1.9 inches, it is especially portable and offers a resettable combination lock and cable.

At about 1.4 pounds, the SEPOX lock box is a lightweight option for moving small valuables between a car, home, office, or travel setting. Its resettable combination and three-foot cable pair portable storage with a way to tether the case to a fixed point.

The listing gives an external size of 8.1 by 5.7 by 1.9 inches and a capacity of 41 cubic inches, helping set expectations for what can be stored. A resettable combination lets the owner set a password, and the included three-foot cable supports anchoring in a car or other location. The product is identified as water- and fire-resistant, and its 1.4-pound listed weight makes carrying it during travel less burdensome than a heavier case.

Skip it if you need room for two pistols; the Z ZLJUAN LT-378K is listed to hold two pistols.

This suits travelers who want a light, resettable-combination box for small valuables and a cable for tethering. Its compact capacity is the key boundary, so it is better for a small load than multiple larger items.

#6

6. Kasdoonx Steel Pistol Safe

• Dimensions: 1.8"D x 6.4"W x 9.4"H
• Weight: 2.7 lb
• Capacity: 2.7 lb
• Material: Carbon Steel

Best for: Ultra-slim coded pistol storage.

Why it ranks #6: The 1.8-inch-thick carbon-steel case includes a cable and soft foam interior; its listed 1,000-plus user-set codes avoid dependence on keys.

At 1.8 inches thick, the Kasdoonx XQH is described as slim enough for under-seat, drawer, suitcase, or backpack-side-pocket storage. Its user-set codes and no-key access pair that low profile with a way to secure a handgun without keeping a separate key available.

The 1mm cold-rolled steel construction includes anti-pry reinforcement, and a steel plate is listed as blocking prying tools. A 4.9-foot braided steel cable with reinforced crimps is specified for anchoring to seats, beds, or hotel furniture. The foam interior cushions contents, while rounded edges are described as protecting vehicle and furniture surfaces from scratches. With 1,000-plus user-set codes and no keys, routine access does not depend on carrying a key.

Skip it if you want biometric entry with a keypad and mechanical keys; the HISHARK GS301 lists all three methods.

Choose this when a thin, coded steel box and a long anchoring cable suit your vehicle storage plan. The foam lining and rounded edges are useful for everyday handling, but the listed access is code-based rather than keyed.

#7

7. Z ZLJUAN Pistol Safe

• Dimensions: 10.43"D x 7.48"W x 2.16"H
• Weight: 5 lb
• Capacity: 0.08 cubic feet
• Material: Carbon Steel

Best for: Room for one or two pistols.

Why it ranks #7: A security cable and carbon-steel construction support vehicle anchoring, while the listed interior dimensions are 7.3 by 8.8 by 2 inches.

The Z ZLJUAN LT-378K is listed to hold one pistol and clips or two pistols, giving it a broader firearm-storage role than a single-handgun-only box. Its included steel security cable can anchor the case to a car seat, furniture, or another fixed object.

The product lists an interior measuring 7.3 by 8.8 by 2 inches, while the listed exterior dimensions are 11.5 by 7.5 by 2.2 inches, providing useful sizing context for a vehicle placement. A high-strength cable supports securing it in multiple locations, and the anti-pry design adds double safety lock buckles. The safe is described for vehicle and hotel use as well as bedroom, living room, or closet storage, so it can travel between settings.

Skip it if you need a lighter, slimmer keyed case; the Younion YSP-6K is listed at 2.6 pounds and 1.81 inches high.

Consider this for drivers who need the stated room for one pistol and clips or two pistols, plus a cable anchor. Check the listed 2.2-inch exterior height against the intended vehicle storage space.

8. Tenamic Keyed Pistol Safe

• Dimensions: 9.5"D x 6.5"W x 1.8"H
• Weight: 2.9 lb
• Capacity: 3.5 lb
• Material: Alloy Steel

Best for: Keyed solid-steel car storage.

Why it ranks #8: This 9.5-by-6.5-by-1.8-inch alloy-steel case includes a key, screw and steel cable, though key-only access offers no listed backup method.

The Tenamic pistol safe uses a key-only locking system, so entry does not depend on batteries or a combination. Its solid-steel construction and included steel cable support a straightforward vehicle-storage arrangement for buyers who prefer physical keys and a tethered lock box.

The 9.5-by-6.5-by-1.8-inch case has a compact, low-profile footprint, and the included steel cable provides an anchoring option. Tenamic describes the solid steel as stronger and the powder-coated surface as anti-corrosion and anti-wear; screws are also included for possible wall or ground fixing. With key-only entry, there are no batteries to run out, but everyday access requires keeping the included key available.

Skip it if you want to enter a code instead of carrying a key; the Amazon Basics SW-SC02 has a combination lock.

This suits drivers who prefer a key-operated steel box and want a cable or screw-based fixing option. Its 1.8-inch profile supports compact placement, while key management remains essential for reliable access.

9. Master Lock 5900D Travel Safe

• Dimensions: 5.3"D x 9.4"W x 2.54"H
• Weight: 0.71 kg
• Capacity: 0.08 cubic feet
• Material: Multi

Best for: Phone and travel essentials.

Why it ranks #9: The 9.4-by-5.3-by-2.54-inch portable safe has a cable, combination lock and charging access port, but is aimed at valuables rather than handgun storage.

A built-in access port lets you charge a device or listen through earbuds while the Master Lock 5900D stays closed. That practical feature makes it a distinctive choice for securing a phone, passport, cash, or cards in a car without disconnecting cables during use.

The 9.4-by-5.3-inch footprint and 0.08-cubic-foot capacity suit a small collection of travel essentials rather than bulky belongings. A cable lets you secure the case to a fixed object, while the user-set four-digit combination avoids carrying a key. Shock-absorbing foam cushions contents, and the product description identifies the construction as water resistant. The access port preserves charging or audio connections while the safe is locked, supporting an in-car setup where a phone remains connected.

Skip it if you need a keypad or fingerprint entry for a handgun; the Grimtron VT1136 has an illuminated keypad and backup-key access.

Choose this for a phone, passport, cash, and cards that need a compact, cable-secured place in the car. Its access port is useful when a device stays connected, but its small capacity is not for larger items.

#10

10. Amazon Basics Security Case

• Dimensions: 9.68"D x 6.49"W x 1.92"H
• Weight: 1.41 kg
• Material: Steel

Best for: Foam-lined combination valuables case.

Why it ranks #10: Its 9.68-by-6.49-by-1.92-inch steel case has a combination lock and foam padding, but no security cable is listed for vehicle anchoring.

A zinc-alloy combination lock and foam-padded interior give the Amazon Basics SW-SC02 a simple, organized format for securing valuables. Its 9.68-by-6.49-by-1.92-inch case is compact enough for discreet storage, with listed uses including documents, cash, jewelry, and firearms.

The anti-pry steel construction provides the case’s structural barrier, while the foam-padded interior helps separate and cushion stored contents. A combination lock avoids key-based entry, and the portable, low-profile form supports travel or discreet placement in a vehicle. Amazon Basics identifies the case as California DOJ certified as a firearm safety device. The 1.92-inch exterior height and 9.68-by-6.49-inch footprint offer practical dimensions to consider when selecting a storage location.

Skip it if you need a cable included for anchoring; the Master Lock 5900D lists a cable for securing the case to a fixed object.

Choose this for drivers who want a combination-locked, foam-lined case for documents or other compact valuables, with a listed firearm-safety certification. Its low profile helps with discreet placement, but no cable is listed for tethering.
