The LiftMaster CM-LBKEY Central Motor Lock Box Key (QTY 2) is a replacement key set designed to open the lockable motor/control compartment on select LiftMaster central motor commercial door operators. These keys provide secure, authorized access for maintenance, manual operation, inspection, and adjustments within the operator’s lock box, helping technicians and facility staff service equipment safely and efficiently.
This part corresponds to LiftMaster part number CM-LBKEY and is supplied as a pair for convenient backup. No programming is required—use by inserting the key into the lock cylinder on the operator’s lock box and turning to open. Compatibility is limited to LiftMaster central motor operators that specifically use the CM-LBKEY profile; always verify your operator’s manual or existing key/lock designation before purchase. For safety, restrict use to trained personnel, disconnect power to the operator, and secure the door in a safe position before performing any service. Common applications include commercial and industrial overhead door systems where controlled access to the operator housing is required.
