Button Smart Remote Key Fob 433MHz for Renault Megana Black

This remote key fob provides a straightforward replacement for a lost, damaged, or worn original key for your Renault Megana. It brings back convenient remote locking, unlocking, and boot release without needing a full dealer replacement. Built with an engineering plastic shell and copper contacts, it is designed for daily handling. The fob works on a 433MHz frequency and contains an ID46 electronic chip (PCF7947) for secure communication with your vehicle. At 82 x 51 x 28mm in a black finish, it is similar in size to the original and can also be customised with screen printing or a card buckle.

Features and Construction

This remote key fob is assembled from materials chosen for durability and electrical reliability. It uses a layered construction to protect the internal electronics while providing a comfortable handheld shape.

Material and Build

The shell is made from engineering plastic, which offers a good balance of toughness and lightweight feel for everyday use. Copper is used for the internal contacts, supporting stable electrical connection when the buttons are pressed. The chip itself is housed in PP material, which provides insulation and protection for the electronics. The three-button layout is arranged for simple thumb operation.

Size and Practical Fit

With dimensions of 82 x 51 x 28mm, the fob is compact enough to fit in a pocket or handbag without adding bulk. The black colour matches most key rings and interior trim. It is specifically noted as for the Renault Megana model, so it should slot into the same slot or ignition and pair with the vehicle’s receiver.

Uses and Placement

This key fob is a dedicated replacement part for a specific car model. Its use case is primarily functional rather than decorative, though the option for screen printing or a card buckle adds some customisation potential.

Event or Professional Use

For automotive locksmiths, garages, or fleet managers, this fob serves as a direct replacement unit. It can be programmed to match a customer’s vehicle without requiring modifications to the car’s existing security system. The screen printing option allows adding a company logo or identifier if needed.

Everyday Home Use

For a private car owner, this fob replaces a lost or broken key, restoring full remote functionality. It is intended for daily operation: locking and unlocking doors and releasing the boot from a short distance. The compact size means it can live on a key ring without being cumbersome.

Benefits and Buying Value

Choosing this replacement fob can save the cost and inconvenience of a dealer-only replacement. It uses established technology that works with many existing vehicle receivers.

Reuse and Low Maintenance

The fob requires no special maintenance beyond occasional battery replacement (battery not included). Its plastic shell resists minor scuffs and the sealed design protects the chip from dust ingress. If the buttons wear from heavy use, the whole unit can be replaced economically.

Why Choose This Product

This fob matches the original spec for the Renault Megana: 433MHz frequency, ID46 PCF7947 chip, and three-button function. It offers a ready-made alternative that can be programmed by a professional or by the user if they have the correct equipment. The black colour matches the original and the compact dimensions ensure a direct fit.
