Volkswagen Polo 6R Touran 1T Button Flip Remote Key 315MHZ 5K0837202AF

Used key – requires programming

The key requires programming (coding) by a specialist to be fully functional.

Volkswagen Polo 6R Touran 1T Button Flip Remote Key is an original component from the Switches, control elements and ignition locks group, designed for Volkswagen vehicles. It is a flip-style remote key with buttons, operating at a frequency of 315 MHz, designed as a factory solution for remote operation of the central locking and ignition lock system.

Application and function in the control system

The presented remote control is a component of the comfort system, responsible for functions such as locking and unlocking the vehicle, and depending on the car's configuration, also controlling additional comfort features. The flip design allows for convenient folding of the key blade, which reduces the risk of mechanical damage in a pocket and improves the ergonomics of daily use.

Button functionality is integrated with the vehicle's electronics, which is why matching this component to the specific equipment version and the central locking system used is crucial. The 315 MHz frequency indicates a specific radio communication standard used in selected market variants of the Volkswagen Polo 6R and Touran 1T models.

Technical characteristics and compatibility

As a factory Volkswagen component, the remote was designed for full integration with the original comfort module and ignition switch. The appropriate internal electronics work with the vehicle's immobilizer system, which enables correct coding and assignment of the key to a specific car (this process must be performed using appropriate diagnostic equipment).

To ensure proper operation, it is essential to verify compatibility with your vehicle based on manufacturer data and the OEM part number. The product also has interchangeable numbers, which facilitates the selection of a replacement within the same family of remotes, while maintaining the correct electrical and communication parameters.

Product condition and potential service applications

The item is offered in a condition described as intended for parts or non-functional, meaning it will work best as a base for obtaining selected components, such as the housing, buttons, electronic board for repair, or other structural details. Such a product can be useful in workshops specializing in remote control regeneration, key duplication, and repairs of locking and ignition control systems.

In service practice, this type of remote is often used for:

• recreating a complete key using functional elements from several units,
• repairing damaged housings and buttons in existing remotes,
• comparative analysis of electronics in the process of comfort system diagnostics.

Benefits of choosing an original Volkswagen component

Choosing an original Volkswagen remote control ensures the preservation of the factory housing geometry, proper fit with the key blade, and compliance with factory safety standards. This allows for precise matching to the ignition switch and door locks, as well as proper cooperation with the immobilizer system after correct coding.

The original component from the Switches, control elements and ignition locks group also facilitates workshop work – electrical and communication parameters are consistent with the manufacturer's documentation, which reduces the risk of problems during adaptation and functional tests after repair or modernization of the control system.

If you are planning a comprehensive repair or modernization of the locking and ignition control area in your Volkswagen and need other elements from the same group, such as remote buttons, control modules, or ignition lock inserts, check the available parts in the Volkswagen switches, control elements and ignition locks category.

Safety and selection of used components

When working with systems responsible for vehicle safety – such as the immobilizer, central locking, or ignition lock support systems – it is crucial to follow service procedures and make an informed selection of used components. It is worth paying attention to the condition of the electronics, signs of tampering, and compliance with the technical documentation of the specific model.
