01

Record what is supplied now

Ask for the number and type of keys accompanying the car and identify which functions have been demonstrated. Two objects photographed together do not prove that both operate the offered vehicle. Keep the key record tied to the VIN and current inspection rather than a generic equipment list.

Distinguish a supplied spare from one ordered, quoted or merely promised. A dealer can consider a conditional offer, but should not mark a future item as received. The receiving team needs a clear count and the actual status at release.

02

Demonstrate ordinary authorised functions

With the owner’s permission, ask the assessor to verify the functions applicable to each supplied key using the vehicle’s instructions. Record results individually. If remote operation works but another expected function is unverified, describe that limitation rather than summarising the key as fully tested.

This is an ownership and handover check, not a reason to bypass the vehicle’s security systems. If access or starting fails, use an authorised service route. Do not treat a seller’s improvised workaround as a satisfactory substitute for the agreed equipment and function.

03

Establish a legitimate replacement route

For a missing spare, contact an appropriate Mercedes-Benz service provider or other legitimate qualified provider accepted for the work. Ask what proof of ownership or authority and vehicle information are required. Requirements, availability and process must be confirmed for the specific vehicle and location.

Do not assume that a blank key advertised online is a complete working replacement. Ask for the full scope, including any applicable setup and verification. Avoid sharing sensitive ownership documents in a broad general enquiry; agree the correct channel with the responsible provider.

04

Price the complete deliverable

Request a quote identifying the vehicle, supplied item, work and completion evidence. Keep the currency, validity and expected availability clear. If the seller will pay, state that in the purchase quotation rather than relying on an informal promise that a spare is cheap.

If the car will be exported before the replacement is completed, ask whether the receiving provider can perform the required work and what remains outstanding. A future availability claim should not be used to suggest that a one-key vehicle is already equivalent to an offer with the agreed keys present.

05

Keep equipment and accounts separate

Key-related convenience features depend on the installed configuration. The equipment review should establish any claimed function independently of the number of keys. A second key does not prove the presence of every comfort-access feature mentioned in an advertisement.

Previous user accounts, stored personal information and connected-service rights need their own legitimate handover arrangements. Do not assume they transfer with a physical key. Record what has been handled and what requires action by the owner or service provider.

06

Use a release checklist that the receiver can repeat

The handover file should identify the number of keys, their checked functions and any pending work. Keep them securely controlled through transport and agree how they are transferred to the responsible recipient. Avoid publishing identifiers or sensitive access information in public sales material.

For a batch, count per vehicle. A box containing enough keys for the order does not establish that each accepted car has the correct set. Use an appropriate private matching record and reconcile it with the final vehicle list before movement.

If the vehicle is offered as new stock, reconcile the keys with the completed PDI and supplied-items record. For a batch order, label and reconcile the supplied key sets against the individual vehicles at release. A total key count is not enough if the sets cannot be matched confidently to the cars. Record any missing or pending item on the relevant vehicle sheet, and agree who will complete it. The receiving dealer should be able to verify the accepted count without relying on a general promise that all accessories are included.

07

Decide how a one-key offer fits the brief

Imagine a suitable C180 with one functioning key and a supplier promise that another will follow. The buyer can require completion before release or assess a clearly documented unfinished offer. The important distinction is whether the missing item is genuinely included and deliverable, not whether it appears as a tick on a generic listing.

State your minimum supplied-key requirement and accepted completion stage when enquiring. Keep the final confirmation with the selected vehicle. A substitute car requires its own count and demonstration, even if the original quotation already mentioned two keys.
