Proximity Keyless Logic: This module functions as a specialized Low Frequency (LF) transmitter antenna that communicates directly with your vehicle's smart key fob. It broadcasts a localized short-range signal to detect when the key fob is near or inside the cabin, enabling seamless push-button start authentication, hands-free passive entry, and proximity trunk release functionality.
Thermal & Distortion Resistance: The hard protective plastic outer shell is composed of a premium automotive >ABS+PBT-GF20< blend (Acrylonitrile Butadiene Styrene and Polybutylene Terephthalate reinforced with 20% glass fiber). This highly durable formulation is specifically engineered to resist extreme thermal distortion, vibrations, and expanding stress when buried deep under the hot dashboard framework or within interior body panels.
🔍 Used, Genuine OEM Electronic Component: This proximity antenna has been carefully extracted from a running donor vehicle, clean-wiped, and thoroughly bench-inspected to guarantee total electrical and signaling safety.
Electronic & Signal Health: The internal solid-state transponder circuits are fully functional, emitting clean, unhindered localization pulses with maximum signal radius and zero proximity authentication delays.
Casing Status: The glass-fiber reinforced plastic housing is solid and uncracked. The mounting holes and alignment tabs are perfect, ensuring a tight and proper installation behind the trim.
Connector Pins: The wiring harness interface plug contains clean, perfectly straight pins free of moisture degradation or oxidation, ensuring continuous voltage stability.
KEY NOT DETECTED FIX: If your car is frequently displaying a "Key Fob Not Detected" error on the dashboard (even with a fresh remote battery), failing to start unless the key is held directly against the start button, or refusing to unlock via proximity handles, a failed or water-damaged keyless receiver aerial is often the root cause.
COMPLIANCE: This part mounts discretely inside the cabin (locations vary from dashboard, center console, to rear parcel shelf depending on model). Please cross-reference your original unit with the manufacturer part number KD45676NXA to guarantee a true plug-and-play fix.
Secure Packaging: Sensitive high-frequency automotive antennas contain delicate solid-state chips. This antenna module will be wrapped in multiple thick layers of shock-absorbing bubble wrap and safely shipped inside a rigid box to prevent transit shifting.
