Remotely open your enclosure door with a card reader, manual release button, or other access control device. These locks have a switch that opens the lock when it receives power from your access system. They can also trigger a light, alarm, or other device to let you know when the lock is open or closed. Closing the door resets the switch. In case of emergency, these locks manually open with a key. Choose them if you need several locks that open with the same key.

Often installed on server cabinets and electrical panels, these locks have a handle that swings smoothly when you lift it to latch and unlatch the door. The handle lies flat when locked, which means it won’t snag anything that passes by.

These locks have a cam that rotates 90° as you swing the handle, so they’re also known as quarter-turn locks. To adjust their fixed latching distance, they come with multiple cams. They also include a stainless steel shutter that blocks rain, snow, and dirt from entering the lock cylinder, which can cause internal damage.

No more lost keys or forgotten combinations—these padlocks open with your Bluetooth-enabled smartphone. Download the lock’s corresponding app to register the lock and control it. Through the app, you can add or remove users, set a schedule for when they have access, and track activity. You can also give short-term access to temporary users, such as contractors or inspectors. All padlocks are battery operated and alert you when the battery is low. If the battery dies, these padlocks remain locked until the power is restored.

Padlocks with a hardened boron alloy shackle are made of the hardest and most cut-resistant shackle material.

Padlocks with a dual-locking shackle withstand attempts to break them open from prying, shimming, or tapping because both ends of the shackle lock inside the padlock body.

Style A padlocks also unlock with a directional code. They’re IP44 rated to withstand damp environments, but not rain or submersion, so they should be used indoors. Use the USB-A port on the bottom of the lock body to recharge the battery.

Style B padlocks have military-grade encryption to protect against common Bluetooth hacking methods. They’ll send an alert to your phone if the lock has been tampered with. You can also unlock them by punching in a directional code. If the lock battery dies, they can be opened using a 9V external battery jumper.

Style C padlocks also unlock with the tap of a key fob. They’re IP66 rated to withstand harsh weather conditions, which makes them great for securing exterior doors all year round. Use the USB-C port on the bottom of the lock to recharge the battery.

Style D padlocks also open with a 10-digit keypad with 40 times as many possible combinations as other styles. With military-grade encryption, they’re protected against common Bluetooth hacking methods. To replace their battery, open the compartment at the bottom of the lock body using a flat-head screwdriver.
