Specify the access package in the agreement
List supplied physical keys, emergency-access components and any additional supported items. Record what is missing, damaged or still awaiting programming. The vehicle equipment review establishes context but does not prove the original key set remains complete on a used car. Ask for a working result, not simply the delivery of a spare shell. Keep key codes and other security-sensitive information private. A promise to send another key later should identify the responsible party and completion requirement before it becomes an unresolved issue across borders.
Demonstrate each physical key independently
Use the applicable instructions to observe locking, unlocking and starting with each item. Arrange a safe procedure that prevents another functioning key from masking a failed one. Record intermittent results rather than repeating until the car happens to respond. A weak remote battery and a starting-authorisation problem are different possibilities, so obtain qualified assessment where needed. Do not force locks or remove trim to discover an emergency method. A dated key-by-key record is more useful than a general video in which several keys are present and only one successful start is shown.
Investigate lost-key and module history
Ask whether keys were lost or locks and relevant electronic equipment were replaced. Obtain appropriate workshop records and the supported action taken to manage access. The service-history guide helps connect those events with dates and mileage. Do not seek security bypass instructions or assume every used module can be commissioned legitimately. Missing paperwork leaves a question for acceptance rather than proving a particular misuse. If further authorised work is needed, identify a competent provider and scope before shipment instead of relying on an informal assurance that the old key will never be found.
Separate optional online services from basic access
Ask which connected features apply to the specific vehicle and destination, and how ownership transfer is supported. Account, subscription and regional conditions may differ from ordinary key operation. Use the MMI and regional-functions review before valuing a seller's phone demonstration. Do not assume that an A3L sourced from China inherits every service advertised for an overseas Sportback. If a function cannot be transferred legitimately, document the limitation and evaluate the remaining usable functions. Basic access should not depend on continuing cooperation from the seller's personal account.
Clear previous-user data through supported controls
Remove or transfer account access where the applicable service supports it, with each party controlling their own credentials. Review paired phones, personal destinations and local profiles without browsing unrelated private information. Preserve necessary service evidence separately and minimise personal data. A factory reset may not remove a server-side ownership association, so verify the relevant processes independently. Do not share passwords as a shortcut. The record should state what was completed, what was unavailable and whether any previous-user permission remains unresolved rather than using a broad reset claim to conceal uncertainty.
Confirm a destination replacement route
Identify a provider able to supply and commission the correct equipment for this generation and market. Ask privately what ownership proof and component information it needs. The VIN-specific parts guide helps avoid ordering from a listing that combines several bodies and systems. Include programming, verification and realistic support constraints in the cost assessment. A low-priced remote is not necessarily a usable key. If only one working key is supplied, make that a visible ownership limitation and resolve the buyer's backup plan before an emergency occurs.
Track the items through dispatch and collection
List the key travelling with the car and the secure route for any spare. Reconcile the inventory using the shipping handover record, then repeat normal access after arrival. Include discrepancies in the first local service brief while the custody trail is still clear. Keep a spare securely separate from the vehicle in ordinary use. The completed handover should give the buyer an understandable inventory, independent access and a known support path, not an optimistic assumption based on one seller-controlled demonstration.
Buyer checklist
- List all supplied and outstanding access items.
- Test physical keys separately.
- Document lost-key work and supported account transfer.
- Confirm replacement capability and shipping custody.
Questions and answers
Is one successful start proof that all supplied keys work?
No. Test each item independently under the applicable instructions so another functioning key does not mask a failed one.
Can I continue using the seller’s connected account?
Use supported ownership transfer where available. Shared credentials can leave privacy and access unresolved and may not provide reliable destination service.
Reference information
Use the applicable market and year documentation for equipment and operating limits. The references have their own market and publication scope; they do not establish the condition, fitted equipment or destination approval of an individual vehicle.
