Wireless 433.92 MHz RF Handheld Remote Control Key Fob (4-Button, EV1527 Learning Code, Sliding Protective Cover, Keyring Clip, Metallic Chrome & ABS Finish)

Product Overview

The KREMOTECONTROLV003 is an industrial-grade, handheld 433.92 MHz radio frequency (RF) wireless remote control transmitter designed for electronic security and access automation platforms. Purpose-built for security alarm systems, motorized garage doors, automated sliding/swing gates, electric strike releases, roller shutters, and smart wireless relay receivers (such as the KRECEIVERV003 module), this compact key fob delivers reliable, encrypted wireless command transmission across short-to-medium distances.

Engineered with a stable 433.92 MHz SAW resonator and an EV1527 learning-code IC (with over 1 million unique code combinations to prevent unauthorized code duplication), the transmitter operates with standard ASK (Amplitude Shift Keying) modulation. The physical unit features 4 independent silicone/tactile buttons clearly labeled (A/B/C/D or Lock/Unlock/Mute/Panic) for multi-channel command execution. Enclosed in a ruggedized metallic zinc-alloy frame and black ABS thermoplastic body, the device includes a mechanical sliding protective cover that slides over the key array to prevent accidental button presses in pockets or tool bags, as well as a heavy-duty metal snap hook for attachment to keyrings and facility management sets.

Key System Features & Functionality

• Stable 433.92 MHz Transmission: SAW resonator stabilization prevents frequency drift caused by temperature variations, ensuring instant response when paired with standard 433 MHz superheterodyne receivers.

• 4-Channel Independent Control: Four physical buttons allow multi-relay operation, such as arming/disarming alarms, opening vehicle gates, controlling pedestrian doors, and triggering auxiliary lighting.

• EV1527 Learning Code Security: Features millions of unique pre-encoded digital combinations, eliminating crosstalk interference between adjacent installations and simplifying wireless pairing.

• Accidental-Press Protection: Mechanical sliding cover shields the keypad surface when carried in pockets or bags, preventing false alarm triggers and unwanted door activations.

• Heavy-Duty Metallic & ABS Chassis: Zinc-alloy reinforced perimeter combined with impact-resistant ABS plastic provides enhanced drop durability and long service life in industrial environments.

• Integrated Keyring & Snap Hook: Includes an all-metal swivel snap hook for secure retention on tool belts, lanyards, or keychains.

• Extended Battery Life: High-efficiency RF output circuit powered by a replaceable 12V 27A alkaline battery, delivering thousands of activations under typical daily usage.
