Advanced Smart Keys & Proximity Entry Systems

Experience the ultimate convenience with our range of Smart Keys and Proximity Fobs. Designed for modern vehicles equipped with push-button start technology, these keys allow you to unlock, lock, and start your car without ever taking the key out of your pocket or bag.

The Next Level of Automotive Security

Unlike traditional remote keys, Smart Keys (often called "Prox Keys") communicate with your vehicle through a series of internal antennas using low-frequency signals. At Locks Down Under, we supply premium aftermarket and genuine smart fobs that match your vehicle's original specifications.

• Passive Entry: Simply touch the door handle to unlock the vehicle when the key is nearby.
• Push-to-Start Compatibility: Fully integrated chips that sync perfectly with your car’s immobilizer and ignition system.
• Rolling Code Technology: Enhanced protection against signal interception and relay attacks.
• Emergency Bypass: All our smart keys include a concealed emergency "pick-key" blade to get you inside if the fob battery dies.

Expert Programming Required

Because Smart Keys are deeply integrated into your car's computer (ECU), they require specialized diagnostic equipment to "marry" the key to the vehicle. We utilize the latest 2026-standard programming tools to ensure a seamless setup.

Based in Canberra, we provide the hardware and technical expertise to replace lost smart keys or provide a spare for your peace of mind. Browse our selection by vehicle make or contact us for a specific compatibility check.
