WHAT TO EXPECT

A key, ready for your day.

Mercedes-Benz C Class vehicles can use different key systems across the listed options. Compare the year and key type below with your existing key, then let us check the registration before arranging the work. Your selected spare-key service includes the key and the cutting or programming needed for that option.

  • One spare key for the selected Mercedes-Benz C Class option
  • Key cutting where the selected type requires it
  • Programming and function checks with the vehicle
  • A compatibility and postcode check before we confirm your appointment

Keep all current working keys available for the appointment. Tell us if a key unlocks the doors but no longer starts the vehicle.

BEFORE YOU BOOK

Your questions,
answered.

Will this key work with my Mercedes-Benz C Class?

The model name alone is not enough to confirm fitment. We check your registration, production year and existing key system before agreeing the work.

What if I have lost every key?

These catalogue prices are for spare-key work where a working key is available. Tell us if no working key remains so we can assess the job and quote for an all-keys-lost service.

Is the key posted to me?

This catalogue is for a mobile key service. We confirm your location and arrange an appointment for the selected cutting and programming work.

What should I send with my enquiry?

Send your registration, postcode, preferred option and whether you have a working key. A description of the existing remote or key card also helps.
