Grimtron Portable Electronic Car Gun Safe
Best for: Drivers seeking a slim electronic handgun safe with backup access options. Its listed dimensions are 11.02 × 7 × 1.85 inches, and it weighs approximately 3.7 pounds. The alloy-steel case has a padded interior, and the product description says its low-profile shape can fit under a vehicle seat.
Access is available through a personal 3–8 digit code or included backup keys. The keypad is backlit, and a USB-C port can temporarily power it from a power bank or vehicle source if the batteries run out. The listed security cable is relevant for buyers who want a way to secure the box.
Consideration: USB-C is for emergency power and does not recharge the batteries. Check the safe’s dimensions against the intended storage location before buying.
AIRMuch Biometric Handgun Safe
Best for: Buyers who need a compact box listed as holding two to three handguns and want more than one access method. The AIRMuch safe supports fingerprint, PIN, and key entry. Its padded interior is intended to protect handguns and accessories from contact inside the case.
An interior LED light helps illuminate the contents in low light, while a mute option lets users silence the keypad. This combination makes it a better fit for shoppers prioritizing biometric entry and quiet keypad operation than for those seeking a basic combination-only lockbox.
Consideration: The product information does not provide dimensions or a security cable detail. Confirm the fit and mounting or securing options for your vehicle before choosing it for trunk storage.
HOLEWOR Handheld Biometric Gun Safe
Best for: Buyers who value a carry handle and want biometric, passcode, and key access. The handheld design is described as suitable for a car, travel, or home use. The product listing says it can store up to 50 fingerprints and supports eight unique six-digit codes.
A display reports temperature, humidity, and battery level. Those readings can help owners monitor the storage environment and battery status; the listing suggests adding dry packs if humidity is too high. Choose this model if those status displays are more useful to you than a low-profile design.
Consideration: The listed details do not include the safe’s dimensions or a security cable. Check whether its handle and shape fit your chosen trunk location.
Dalmbox Compact Portable Handgun Safe
Best for: Shoppers who want a slim lockbox with straightforward combination access. The listed exterior dimensions are 9.4 × 6.4 × 1.8 inches, with interior dimensions of 9.1 × 6.1 × 0.9 inches. The listing describes a 3-digit combination lock and notes a key-lock option with two keys.
Its compact profile is described for vehicle compartments, luggage, drawers, and other storage areas. The product is also presented for organizing items such as cash, passports, and jewelry. Compared with biometric models, this is a simpler choice for buyers who prefer a combination lock.
Consideration: The interior depth is 0.9 inches, so compare that measurement with the item you plan to store. The listing does not specify a biometric entry method.
STOPBOX Mechanical Handgun Storage
Best for: Buyers who want a mechanical access system without batteries or electronics. The product describes a user-set combination system with 81 possible combinations and says it is designed for compact handgun storage. The listing identifies this two-pack as full-size only.
STOPBOX may be a better fit than an electronic safe for shoppers concerned about battery dependence or electronic keypad issues. The listing also describes the product as TSA compliant and compatible with padlocks or security cables.
Consideration: Padlocks and security cables are not included, according to the product details. Confirm that the full-size-only configuration matches your intended handgun and storage needs.
Buying Guide: How to Choose a Car Trunk Gun Safe
Which lock type fits your routine?
Choose between keypad, biometric, combination, and mechanical access based on the method you can operate and maintain. The Grimtron uses a code with backup keys; AIRMuch and HOLEWOR offer biometric access alongside other methods; Dalmbox lists combination and key options; and STOPBOX uses a mechanical combination system. Backup access can matter if an electronic method is unavailable, but the listed backup options vary by model.
Will it fit in your trunk?
Compare the product’s exterior measurements with the exact compartment or mounting location. Also consider interior dimensions, especially if you plan to store accessories with a handgun. Only some listings provide specific measurements, so request or verify dimensions when they are not stated.
How will you secure and maintain it?
Look for a listed security cable or compatible attachment if you want to secure a safe to a fixed point. Do not assume a cable is included: STOPBOX says accessories are not included, and other listings may not specify one. For electronic models, review battery and emergency-access details. Follow applicable laws and safe-storage practices when transporting firearms.
