Changan UNI-Z Keys and Connected-Account Handover

Record the actual access inventory

Ask which remotes, emergency keys and any supported digital access items are included. Compare the seller's list with the applicable vehicle information rather than assuming every trim was supplied identically. Test each item individually with other keys prevented from influencing the demonstration. Record missing items and previous replacement work. A key that unlocks a door has not necessarily demonstrated every required function. Include any aftermarket alarm or access modification in the record so it cannot surprise the buyer or carrier later.

Verify normal starting through the correct procedure

Have the seller demonstrate the vehicle's normal ready or start sequence according to its powertrain instructions. Do not confuse quiet hybrid readiness with a failed start, or engine operation with proof that all key functions are correct. The gasoline and iDD identification guide helps keep the test appropriate. Record intermittent messages and refer them to a competent technician. If low vehicle voltage is suspected, use the 12V assessment rather than repeatedly boosting or resetting the car until one attempt succeeds.

Check emergency access without requesting a bypass

Obtain the applicable instructions for legitimate emergency entry and any documented procedure for a weak remote battery. A qualified person should demonstrate the method without damaging trim or exposing security credentials. Do not ask for immobiliser bypasses, hidden service codes or instructions to defeat ownership checks. Keep sensitive key information out of the ordinary enquiry form and broadly shared inspection files. The purpose is to ensure the buyer can follow the manufacturer's approved recovery procedure, not to create an unofficial access method that undermines security.

Establish what an account transfer actually requires

Ask which connected functions are supported for the original market and whether the manufacturer offers an ownership-transfer process usable by the buyer. Identify legitimate requirements such as ownership verification without sharing passwords or one-time codes with the seller. A working app tied to the previous owner's number may stop being useful after delivery. Classify each function as confirmed, unavailable or still awaiting evidence. Do not price remote features as included benefits when destination availability remains unverified, and do not promise that changing the display language solves account-region restrictions.

Resolve previous-owner access through supported channels

Where account release is available, agree who completes it and how the buyer verifies the result. Personal profiles, contacts and saved locations should be handled through the documented process after relevant inspection evidence is retained. Avoid indiscriminate factory resets before the service provider confirms their consequences. If missing keys need de-authorisation or replacement, obtain a VIN-specific plan from a competent provider. The parts-matching guide is relevant because a matching remote shell does not prove compatible electronics or programming support.

Control the key handover during shipping

List the access items in the carrier handover record and agree how they are identified, secured and reconciled at arrival. Give the carrier the appropriate normal operating instructions for the gasoline or iDD version. Do not disable security through unsupported changes simply to simplify transport. Use the shipping and handover guide to preserve the custody trail. If the buyer receives fewer items than agreed, document the discrepancy promptly rather than waiting until a spare key is needed months later.

Make the final acceptance owner-controlled

Retain a private inventory, replacement-work records and the support contact for legitimate recovery. Separate unresolved app convenience from unresolved physical security so the buyer can make an informed decision. A documented lack of remote services may be acceptable; an unexplained missing key or reliance on the seller's account deserves a different response. If the candidate changes, repeat the access and account checks. The final handover should not depend on the former owner's continued cooperation for ordinary use or expose their personal data to the new owner.

Buyer checklist

• Test and inventory supplied keys independently.
• Use the correct gasoline or iDD start procedure.
• Separate app claims from supported account transfer.
• Secure the transport inventory and legitimate recovery route.
