Imagine a system that will fundamentally change how you access and start your vehicle. Designed and built based on the popular luxury vehicle’s hands-free keyless access and start function; by carrying a thin-profiled access card you will have complete access and ignition control over your vehicle without taking out keys or pressing buttons on the remote. Built with the latest secure RFID technology and combined with rolling-code encryption, this system will provide the best possible aftermarket vehicle access convenience, security and more.

How Does It Work

As you approach the vehicle, within a 2 to 3 meter range your access key will be detected and verified by your vehicle through multiple layers of Radio Frequency Identification.
Once the vehicle validates your access key, the door locks will be released and by simply pulling the door handle, you now have exclusive access to your car. No more fumbling for keys or the remote.
After entering the vehicle you may step on the brake and push in the ignition knob. Turn the knob, just like you would with a key to start the engine.
Simply walk away from your vehicle with the access key – your vehicle will lock and arm immediately. You’ll never forget to lock the doors behind you again.

Convenient Access Keys
  • Thin and compact, easily tucked away in your pocket or wallet.
  • Built-in 3D RFID antenna for reliable RF sensing in any orientation.
  • Built in multi-functional buttons for manual door lock control, trunk release and remote start.
  • Low power consumption lasting 18+ months based on typical daily usage.
Ignition Controlled Lock / Unlock
Your vehicle will have the ability to automatically lock the doors after turning ON the ignition and automatically unlock when the ignition is turned OFF.
Bypass Transponder Card / Emergency Access and Ignition
To prevent situations such as lost or damaged access keys, the credit card sized Bypass Transponder Card provides an alternate way of accessing and starting your vehicle. Wave the transponder card over the bypass antenna to disarm, unlock and enable the push-start igntion all at the same time. Never worry about loosing or forgeting your keys again.

Dual-Antenna System
From sub-compact cars to full size SUV, the ability to operate two antennas simultaneously provide a complete signal coverage regardless of the vehicle size; effectively reduce installation complexity.
Knob Switch Key Cap
Convert a regular key into a Switch-Start System that seamlessly becomes a part of your vehicle. Advanced Keys' Smart Keyless Entry – Knob-Start System allows you to operate your vehicle by turning the knob switch like you would normally with a regular key -  a simple yet cost effective way to achieve keyless ignition without the extensive modification required for the Push-Start ignition.
Easy DIY Key Conversion
The simple Do-It-Yourself conversion is simple to follow and easy to do. But if you are still unsure, we can also do it for you. Just send us your key after you purchase the product and we will return it to you converted.

Security Features
Advanced Keys products are developed on the foundation of security, you can rest assured knowing our products are safe and cannot be easily defeated even with sophisticated means.

Multi-Layered Secure Communication
Unlike traditional aftermarket keyless entry devices which operate over unsecure, open radio frequency, Advanced Keys product offers multi-layered, dual-frequency communication systems. Built with the latest RFID Mutual-Authentication protocol it offers the highest "hand-shaking" security which prevent conventional transmitter code-scanning, sniffing and hijacking. Working together, the UHF authentication layer with code-hopping and encryption technology provide the better protection than OEM keyless entry remote.

 Anti-Theft and Starter Disable Function
In additional to the smart keyless entry function, this is also an alarm system that monitors door switches, brake and ignition. Vehicle ignition can be operated only when a valid access key is identified. When an unauthorized entry and/or vehicle activation attempt is detected, the ignition relay will be disabled; prevent engine from starting.

   Multi-Color LED and Alarm Record
This multi-color LED will provide you with a visual reference about the status of the system/vehicle and simulates as an anti-theft deterrence feature.
Auto Windows Closing (Optional Module)
When the doors are locked after the driver leaves the vehicle, system can automatically close all open windows one by one. The added security prevents unauthorized access and protects the vehicle from water intrusion.

How do I know if my vehicle's metal key is compatible for the key cap conversion?
Key is compatible for conversion as long as the metal key blade have some length exposed after shaving off the handle and with the key fully inserted into the key cylinder. Please make sure key is fully inserted in the key cylinder when measuring length since some vehicle require pushing the key into the cylinder before it allows you toggle the key.
