The Keystone / Heddolf Wireless Keypad is a 300 MHz keypad designed for compatible Multi-Code 10-switch receiver systems. It is commonly used with Multi-Code 109020, 109950, and 109920 receivers to add keypad entry to a gate operator, garage door opener, commercial door operator, or access-control installation.
This keypad is commonly associated with the Heddolf / Keystone M330-1KB style keypad. It is designed for Multi-Code-compatible fixed-code receiver systems, not for modern rolling-code garage door openers that program directly with a learn button. The receiver must support the correct 300 MHz Multi-Code 10-switch format for the keypad to work properly.
The keypad supports a master code along with up to 60 individual four-digit user codes. That makes it a good option for small communities, private gates, service entrances, commercial properties, shops, warehouses, and controlled-entry locations where several users need keypad access without handing out individual remote controls.
The keypad sends a wireless 300 MHz Multi-Code signal to a compatible receiver. When a valid code is entered, the receiver provides the relay output to the connected gate operator, garage door opener, commercial door operator, or access-control device.
The keypad itself does not operate the gate or door directly. It communicates with a compatible receiver, and the receiver is what connects to the operator or control equipment. If there is no compatible Multi-Code receiver on the system, one must be installed separately.
This Keystone / Heddolf wireless keypad is intended for compatible 300 MHz Multi-Code 10-switch receiver applications. Compatibility depends on the receiver model, frequency, coding format, wiring, power, and operator input being used.
This keypad should be matched to the receiver, not only to the gate operator or garage door opener brand. A LiftMaster, Linear, Genie, DoorKing, All-O-Matic, Viking, FAAC, HySecurity, or other operator may use this keypad only if a compatible Multi-Code receiver is installed and wired correctly.
Verify the exact receiver model before ordering. Multi-Code receivers can look similar, but power input, mounting style, relay wiring, and receiver frequency may differ by model.
This keypad is for compatible Multi-Code 300 MHz 10-switch receiver systems. It should not be ordered just because the gate opener or garage door opener has a keypad input. The system must have a compatible receiver that can accept the keypad signal.
The most common ordering mistake is confusing Multi-Code 300 MHz equipment with other fixed-code or rolling-code systems. Multi-Code, MegaCode, Delta-3, Security+, Security+ 2.0, MyQ, Intellicode, and Stanley-style systems are not automatically interchangeable.

This keypad is a good choice when the site already has a compatible Multi-Code 300 MHz 10-switch receiver, especially the 109020, 109950, or 109920. It is not identified by the gate opener brand alone. The receiver is the part that determines whether the keypad will communicate with the system.
If the customer has a newer garage door opener with a learn button, MyQ logo, Security+ remote, MegaCode receiver, or rolling-code receiver, this keypad will not usually program directly. In those cases, the system may need a compatible external Multi-Code receiver, or the customer may need the keypad made for the existing receiver technology.
Programming depends on the keypad version and the receiver being used. In most Multi-Code-compatible applications, the keypad must be set to the correct Multi-Code format and matched to the receiver's code setting. The master code is then used to manage user codes.
For best results, program and test the keypad near the receiver before final mounting. After it works reliably at close range, mount it in the intended location and test again. If operation is inconsistent, check battery condition, receiver antenna location, keypad distance, metal obstructions, and nearby electrical interference.
Wireless keypads are simple to use, but receiver compatibility matters. A keypad that is correct for a Multi-Code receiver will not automatically work with a different receiver technology. For shared gates, commercial doors, apartment properties, and managed access systems, keep a record of the master code and user codes so access can be updated when tenants, employees, or vendors change.
Do not use a wireless keypad as a substitute for required gate safety devices. Photo eyes, safety edges, monitored entrapment protection, warning signs, and proper gate hardware must remain installed and operating as required for the gate system.
This keypad is commonly used with compatible Multi-Code 300 MHz 10-switch receivers, including Multi-Code 109020, 109950, and 109920 receivers.
This keypad is commonly listed as a 300 MHz Multi-Code-compatible keypad. The receiver must support the matching 300 MHz Multi-Code format.

Yes. It is commonly listed for indoor or outdoor mounting and includes a weather-resistant enclosure with a stainless steel faceplate and polycarbonate housing.
Only if the opener is connected to a compatible Multi-Code 300 MHz receiver. It does not directly replace LiftMaster Security+, Security+ 2.0, MyQ, Genie Intellicode, or other rolling-code keypads.
Do not assume the receiver is included unless the current package specifically says so. This product is the keypad. The compatible Multi-Code receiver may need to be purchased separately.
