GRX130 Smart Key Assembly

Description

The Toyota GRX130 Smart Key Assembly is an advanced keyless entry and ignition system designed for the Toyota Mark X GRX130 models. Built to OEM standards, this system allows drivers to unlock, lock, and start the vehicle without physically inserting a key, improving both convenience and security.

Specifically compatible with Toyota Mark X GRX130 (2009–2016 depending on trim and market specifications), the smart key assembly integrates with the vehicle’s immobilizer, ECU, and push-start system for seamless operation.

This smart key system enables:

• Keyless entry and exit
• Push-button engine start/stop
• Remote locking and unlocking
• Anti-theft immobilizer security
• Hands-free driving convenience

According to Toyota’s smart key system design, the vehicle detects the electronic key within a certain range, allowing automatic door unlocking and engine start when the brake pedal and start button are engaged.

The GRX130 smart key system works together with the smart key control module and ECU, ensuring encrypted communication between the key and vehicle for improved theft protection and system reliability.

Common issues that may require replacement include:

• Smart key not detected
• Push start not responding
• Intermittent locking/unlocking failure
• Damaged or lost key fob
• Immobilizer communication errors

Replacing the smart key assembly or control unit restores full keyless functionality, improves security, and ensures smooth vehicle operation.

Installation and programming should be carried out by qualified automotive locksmiths or technicians to ensure correct coding and synchronization with the vehicle’s immobilizer system.
