Mercedes-Benz GLA Keyless Go Upgrade Review

Unlock Ultimate Convenience: Mercedes-Benz GLA Keyless Go Installation

Imagine unlocking and locking your Mercedes-Benz GLA220D without ever reaching for your smart key. This is the reality with the Keyless Go upgrade, a popular factory option that significantly enhances the convenience of your vehicle. This review details a recent installation, showcasing how this advanced feature transforms daily driving.

The Keyless Go system operates on a simple yet ingenious principle: proximity-based access. With the smart key safely stored in your pocket or bag, you can lock the vehicle by simply touching the door handle. To unlock, a gentle grip on the handle is all it takes. This eliminates the need to fumble for your keys, especially when your hands are full.

The Keyless Go Installation Process for Your GLA220D

Installing the Keyless Go system on a Mercedes-Benz GLA220D involves a precise, multi-step process to ensure seamless integration and functionality. The procedure prioritizes maintaining the vehicle's original wiring integrity.

1. Door Handle Replacement: The process begins with the replacement of the driver and front passenger door handles. These new handles are equipped with the necessary sensors for the Keyless Go system.
2. Wiring Integration: Crucially, the installation is performed without damaging the original wiring harness. New wiring is integrated using original pins, ensuring a clean connection that allows for easy restoration to factory settings if ever needed and protects the vehicle's electrical system.
3. Component Coding: Following the physical installation, the vehicle's Electronic Control Unit (ECU) requires coding. For Mercedes-Benz vehicles, this step is mandatory to activate the new Keyless Go functionality. Without proper coding, the new hardware will not operate.
4. Color Matching and Painting: To ensure a factory-perfect aesthetic, the new door handles are painted to match the GLA's original paint color. This step requires careful attention to detail and adequate drying time.

While same-day installation is often possible, it's advisable to schedule at least 1-2 days to allow for precise color matching and paint curing. The cost for this upgrade typically ranges from ₩1,500,000 to ₩2,500,000, encompassing parts, painting, installation, and coding. Factors influencing the price include the complexity of the paint color (specialty paints may incur additional costs) and the specific grade of parts used (OEM vs. aftermarket). It's recommended to provide your vehicle's color name or code when requesting a quote to ensure a perfect match.

Experiencing the Convenience of Keyless Go

The practical benefits of Keyless Go are most apparent in everyday scenarios. Carrying groceries, managing children, or simply being in a hurry becomes significantly less cumbersome. The sensitive sensors detect your hand's proximity, allowing for effortless operation even with gloves on in colder weather. This factory option truly elevates the user experience, making your Mercedes-Benz GLA220D feel more modern and user-friendly.
