Customer concern or upgrade request

The W213 arrived without the factory Keyless Go function, and the owner requested keyless access.

Inspection and diagnosis

The recorded work began with a vehicle compatibility assessment and system coding.

Repair and upgrade work

This W213 arrived without the factory Keyless Go function. We performed a plug-and-play upgrade to the original Mercedes-Benz Keyless Go system — enabling keyless entry, exit, and boot access without pressing the remote buttons, matching the convenience and behaviour of a factory-equipped vehicle.

  • Vehicle compatibility assessment and system coding
  • Plug-and-play OEM Keyless Go module installation
  • Keyless open and close door function setup
  • Keyless comfort access and rear boot release configuration

Components used in this case

  • OEM Mercedes-Benz Keyless Go module installed plug-and-play

Testing and verification

The documented result confirms keyless door operation, comfort access and keyless rear boot release without pressing the remote buttons.

Documented outcome

Full Keyless Go functionality enabled: doors lock and unlock on approach, comfort access operates as per factory specification, and the rear boot opens keylessly. No remote button presses required for daily use.
