Renault Car Key 2-Button 433mhz with PCF7946 Chip Blade NE72/73

Purpose and Scope of Application

The key is designed to replace the original Renault car key operating at 433mhz and equipped with a PCF7946 (ID46) chip. It is used to restore the key set in case of loss, damage to the housing, electronic failure, or when an additional spare key is required. The key is suitable for Renault models that use the NE72/73 blade and correspond to the PCF7946 board type.

Design Features

The housing is made of durable material and features a classic two-button layout for lock and unlock functions. The electronic board includes a PCF7946 chip that ensures proper immobilizer operation. The NE72/73 blade is made of metal and requires mechanical cutting to match the ignition lock of your vehicle. The reinforced construction protects internal electronic components, and the ergonomic casing ensures a secure and comfortable grip for daily use.

Compatibility

The key is compatible with Renault vehicles that use:
– 433mhz frequency;
– PCF7946 (ID46) chip;
– NE72/73 blade type;
– two-button control board.

Before purchasing, it is recommended to verify the type of your original key to ensure full compatibility.

Advantages of Use

The key allows you to replace a damaged or worn housing, restore button functionality or electronic components, and fully reinstate immobilizer operation. It is a practical solution for obtaining a spare key or replacing the main one. The durable housing ensures long service life, while the internal electronics are protected from external impact. The casing is unbranded, making the key a universal replacement for the original unit.

How to Use

After purchase, the key must be cut by a professional based on your original key and programmed to synchronize the PCF7946 chip with your vehicle. The procedure is performed by automotive key specialists. Once the blade is cut and the chip is programmed, the key functions as the original and is ready for daily use.

Recommendations for Selection

This key is recommended if your vehicle uses an original 2-button key with 433mhz frequency and a PCF7946 chip. If you are unsure about compatibility, compare the appearance, markings, or internal board layout of your old key. This helps prevent mismatch issues and ensures correct operation after programming.
