Key specs explained
Connectivity: 318MHz
This radio frequency allows the keypad to communicate with your garage door opener without physical wires. It operates on a dedicated band, reducing interference from other household devices. You benefit from reliable signal transmission through walls or doors. When comparing smart locks, check if they use Wi-Fi or Bluetooth, as those require different network setups. This frequency is specific to garage opener compatibility.
Access Method: 1 to 6 digit PIN
You enter a custom code between one and six characters to open the door. This allows for quick access without carrying a remote. Shorter codes are faster to enter, while longer ones offer slightly more security. You can choose a PIN that is easy for family members to remember. Compare this to smart locks that require smartphone apps or fingerprint scans, which may have different speed and usability trade-offs.
Security Technology: MegaCode
MegaCode is Linear’s rolling code technology that changes the signal each time you press a button. This prevents thieves from capturing and replaying the signal to open your door. You get enhanced protection against code grabbing attacks. When shopping for video doorbells or smart locks, look for similar encryption standards. This technology ensures that the command sent by the keypad remains unique and secure for every single use.
Opener Compatibility: Linear LDCO863B, LDCO841, LDCO850, LDO50
This keypad works only with specific Linear garage door opener models. You must verify your opener’s model number before purchasing to ensure it functions correctly. It replaces older Linear models like LPWKP. Unlike universal smart locks that work with many brands, this device is brand-specific. Check your opener’s manual or label to confirm it matches one of these listed models for successful installation and operation.
Design and Build Overview
The Linear Wireless Garage Keypad measures 5 inches in height, with a width and length of 2 inches each. According to the listing, the exterior is finished in light gray, also described as off-white. This neutral color helps the unit blend into most garage environments without drawing unnecessary attention. The compact dimensions allow for straightforward mounting on standard garage door frames or interior walls. You do not need to account for a large footprint when planning the installation spot.
The keypad features a hinged cover designed to protect the buttons from dust, rain, and other weather elements. This physical barrier is crucial for outdoor or semi-outdoor placement, ensuring the electronic components remain dry and functional. The cover also shields the soft blue backlight, which illuminates the keypad for nighttime use. This lighting feature allows you to enter your PIN clearly in low-light conditions, enhancing convenience and security during evening hours.
Access is managed through a standard numeric keypad layout. You can program a PIN ranging from 1 to 6 digits or letters. The MegaCode security technology is integrated into the unit to encode these signals. This design choice means you benefit from secure wireless communication with compatible Linear garage door openers. The build prioritizes durability and ease of use, focusing on practical access control rather than aesthetic complexity.
