“The key does not work” can mean the buttons do not unlock the doors, the vehicle does not recognise the key for starting, or both. Begin by describing exactly which function fails. Keep the complete 01176 entry and the name of the controller that stored it.
Separate locking from starting
Ross-Tech’s 01176 reference distinguishes immobiliser-related causes, such as the reader, its wiring or the transponder, from remote-control causes, including the remote’s battery. It notes that these are generally separate systems. A replacement button-cell battery is therefore not a universal answer to a start-authorisation problem. Read the 01176 technical reference.
Compare the keys without changing anything
- Does each available key operate the remote locking?
- Does each key start the vehicle normally?
- What exact dashboard message or immobiliser warning appears?
- Did the issue begin after key damage, water exposure or module replacement?
- Has anyone already attempted key adaptation or fitted a used component?
Record the results for each key separately. A simple account such as “original key starts but its buttons do not work; spare key does both” is more helpful than “both keys faulty”. Keep your existing keys and original modules available while the repair route is being assessed.
Programming should follow diagnosis
Before booking programming, establish whether the key and installed components are suitable for the vehicle and whether the underlying fault has been identified. Repeated adaptation attempts do not substitute for investigating a reader, supply or communication problem. Security-related work should use the appropriate authorised process for the vehicle.
Send AXION the vehicle details and complete fault report. Please do not publish key security data in public comments. Ask what identification and items are needed for the appointment. Explore keys and access electronics and the module finder.
