StopBox Co-Pilot: Battery-Free Vehicle Pistol Lockbox

The StopBox Co-Pilot is a lockbox built for one pistol in one place: the gap between a vehicle seat and the center console. StopBox USA, the Spokane Valley, Washington company known for its battery-free handgun boxes, designed it specifically for vehicles. The box sits upright beside the seat cushion, out of sight, with the lock face toward the front of the cabin where your hand finds it.

The point is a dedicated, consistent spot. A pistol in a glove box or center console shares space with paperwork and chargers, and a pistol under the seat slides around. The Co-Pilot keeps the pistol locked, out of view, and in the same orientation on every drive.

The Co-Pilot opens on StopBox's patented hand-gesture lock, a purely mechanical combination you enter by pressing the lock's buttons with your fingers. There is no screen, battery, or circuit board. Enter the code and the lid opens to present the pistol grip-up, in the same ready-to-draw position every time.

A mechanical key lock is built in as a second layer, and two keys come in the box. StopBox photographs the key on a yellow "Pull to Eject" lanyard. A lock with no battery suits a car: keypad, RFID, and biometric safes need power, which in a parked vehicle usually means batteries living through summer cabin heat and winter cold, with the backup key as the way in when they run down. The Co-Pilot has nothing to charge.

The Co-Pilot installs with StopBox's Universal Seat Adapter in under two minutes, according to StopBox, with no drilling, tools, or permanent changes to the vehicle. A rubber-coated steel security cable then ties the box to the seat base. StopBox shows it fitted in a full-size truck, an electric car, a classic car, and a side-by-side, and says the adapter fits most vehicles.

It is also the first fully ambidextrous StopBox. It mounts on the driver's side or the passenger's side of the console, so a right-handed driver, a left-handed driver, or a passenger can each set it up on the side they reach with.

StopBox says the Co-Pilot fits most pistols, from compact handguns to full-size pistols with a mounted optic and weapon light. Weapon light spacers come in the box to fill the space around pistols of different lengths. StopBox has not published interior dimensions, so confirm fit before buying if you run a long-slide pistol or an oversized light.

The housing is high-strength polycarbonate-ABS in black. StopBox includes the Co-Pilot, the Universal Seat Adapter, two keys, the weapon light spacers, and the security cable.

StopBox lists the Co-Pilot at $349, available in November 2026, with a 30-day money-back guarantee and a limited lifetime warranty. That is more than the $229.99 Vaultek Slider Essential and the $219.99 Hornady RAPiD Safe 2700KP, and well above the $32.99 SnapSafe Lock Box XL. A Co-Pilot is on its way to us for hands-on testing of install time, draw from the seat, and fit with light-bearing pistols.
