Technical Specifications

Key Features & Benefits

Multi-Version & Multi-Model Compatibility

With three available versions, this smart remote key caters to both keyless go and non-keyless go Porsche vehicles. The OEM PCB Aftermarket Shell version combines the stability of an OEM circuit board with the cost advantage of an aftermarket shell. It supports five Porsche model series, covering a wide range of production years, making it a highly versatile key option.

Dual Unlocking Modes

Equipped with a HU66 key blade, this key supports both smart remote control and mechanical unlocking. The mechanical unlocking function serves as a critical backup when the key battery dies or the smart system malfunctions, ensuring you never get locked out of your vehicle.

Advanced Chip & Signal Stability

The PCF7953P/HITAG PRO/49 CHIP provides encrypted signal transmission, preventing unauthorized access and enhancing vehicle anti-theft performance. The 315MHz frequency is optimized for Porsche’s vehicle electronic system, ensuring strong signal penetration and quick response even in complex environments like parking garages.

Working Principle

The Porsche smart remote key relies on encrypted radio wave signal interaction to achieve vehicle control. When a button is pressed, the key emits a unique encrypted 315MHz radio wave signal. The vehicle’s antenna receives this signal and transmits it to the onboard immobilizer system and electronic control unit for dual verification. After the signal is authenticated as valid, the system sends commands to the corresponding actuators to complete actions such as unlocking doors, opening the hood, or triggering the panic alarm. For keyless go versions, the key can also automatically disengage the immobilizer and activate the ignition system when it is within the vehicle’s detection range, realizing a truly keyless driving experience.

Installation & Usage Tips

Mechanical Unlocking Operation

For emergency situations, Porsche vehicles have a hidden mechanical lock cylinder on the main driver’s door handle. Remove the small cover on the door handle, insert the HU66 key blade, and rotate it to mechanically unlock the door. It is recommended to operate this function periodically to prevent the lock cylinder from seizing due to long-term inactivity.

Version Selection Guidance

If your Porsche is equipped with a keyless go system, you can choose either the Aftermarket (keyless go) version or the OEM PCB Aftermarket Shell (keyless go) version. The latter offers better compatibility with the original vehicle system. For non-keyless go models, select the Aftermarket (non-keyless go) version to avoid unnecessary function redundancy.

Programming & Maintenance Notes

This key requires programming by a professional locksmith with Porsche-specific matching equipment. After programming, test all functions to ensure they work properly. To extend battery life, avoid pressing the key buttons frequently when the key is not in use, as this will consume power unnecessarily.

FAQ

Does this key support the 2018 Porsche Macan?

Yes, it is compatible with 2015-2017 Porsche Macan models, but not with 2018 and later versions due to updated vehicle electronic system configurations.

What is the difference between the OEM PCB Aftermarket Shell version and the regular Aftermarket version?

The OEM PCB Aftermarket Shell version uses an original equipment manufacturer circuit board, which offers better compatibility and stability with the Porsche keyless go system. The regular Aftermarket version uses a third-party circuit board and is more cost-effective.

How can I maintain the lock cylinder to prevent it from seizing?

It is recommended to use the mechanical unlocking function once every 1–2 months. You can also apply a small amount of specialized lock cylinder lubricant to keep it in good working condition.
