Smart Key Programming: what to know first
Proximity and push-start smart keys must match the vehicle system and may require vehicle-specific registration procedures.
Smart keys are vehicle-specific
Appearance alone does not confirm compatibility. Frequency, board type and vehicle system can matter.
Send photos before arranging service
Front, back and any available internal or part-number information can reduce compatibility mistakes.
About this key programming service
Vehicle key systems differ by make, model, year and key type. Compatibility is checked from your vehicle details before service is confirmed.
Smart Key Programming service
Smart key programming is for vehicles that use proximity or keyless-start systems where the driver can unlock or start the vehicle without inserting a traditional ignition key. These keys communicate electronically with the vehicle and can differ by frequency, board type, part number and market specification. A smart key that looks identical on the outside may therefore be unsuitable for a particular vehicle.
This service can be relevant when adding a spare smart key, replacing a lost or damaged smart key, or recovering supported vehicles after all smart keys are lost. Before confirming a job, we need the exact vehicle details and information about the key you have or plan to use. Compatibility is especially important with imported vehicles because similar models can use different key specifications across markets and production years.
Adding a spare smart key
If one smart key still works, adding a spare is usually the best time to investigate a second key. Send photos of the working key and the vehicle year/model. Where visible, part or board information can help identify the correct replacement. Keeping a second working key can also reduce the disruption of a future lost-key situation.
All smart keys lost
An all-keys-lost smart-key job is different from simply adding another key. Vehicle support, security access and required procedures vary considerably. Tell us clearly that no working smart key remains. We will check the vehicle information before confirming whether the job is supported and what preparation is needed.
Smart key not detected
A “key not detected” message does not prove that programming has been erased. A weak key battery, damaged smart-key electronics, vehicle battery condition, antenna or receiver issues and other faults can produce similar symptoms. If a spare key works normally, mention that. If neither key works, explain when the problem started and whether any vehicle electrical work was recently performed.
Buying a replacement smart key
Do not select a replacement solely by shell shape or button layout. Confirming electronic compatibility is more important than appearance. If you already have a replacement, send photos and identifiers before booking. If you have not purchased one yet, send the vehicle details first so the likely specification can be checked.
What information should you send before booking?
Correct vehicle identification is one of the most important parts of automotive key work. Send the exact vehicle make, model and year, your location, and a clear photo of the existing key or remote if you have one. Also tell us whether at least one working key is still available. If you have already purchased a replacement key, send photos of the front, back and any label, part number or board information that is visible. These details help us check whether the key type and programming procedure are likely to match your vehicle before a visit is arranged.
- Vehicle make, model and year
- Your current location
- Photo of the existing key, remote or smart key
- Whether a working key is still available
- Photos or part details of a replacement key you already purchased
How our booking process works
Start by sending the vehicle and key details. We review the information to identify the likely key system and confirm whether the requested work is suitable for the available equipment and key type. If more information is needed, we may ask for an additional photo or vehicle detail before confirming the job. Once compatibility and availability are checked, the service can be arranged. This approach is more useful than dispatching first and discovering on site that the replacement key, frequency, transponder or procedure is not suitable for the vehicle.
- Send the details: make, model, year, key situation, photos and location.
- Compatibility check: the likely key type and required procedure are reviewed.
- Confirm the service: availability is confirmed before the job is arranged.
Why compatibility must be checked first
Two vehicles that look similar can use different immobilizer systems, remote frequencies, smart-key boards or programming procedures depending on year, market specification and trim. A key shell that physically looks correct is not enough to confirm electronic compatibility. For that reason, we avoid promising that an unknown key will work based only on appearance. Supplying accurate vehicle details first reduces wasted visits, incorrect key purchases and unnecessary programming attempts.
If you are unsure which service you need, send the vehicle details and describe the problem in simple terms. For example: “I have one working key and need a spare,” “the remote buttons stopped working,” “the smart key is not detected,” or “all keys are lost.” We can then direct the enquiry to the most relevant service.
Questions about smart key programming
Can every vehicle be handled the same way?
No. Key and lock systems vary by manufacturer, model, year and market. We confirm support from the vehicle details before arranging the service.
Should I buy a replacement key before contacting you?
Not necessarily. If you already have one, send its details. If you have not purchased a key yet, checking the vehicle specification first can reduce the risk of buying an incompatible key.
Do I need to bring the vehicle somewhere?
Mobile availability depends on the service, vehicle and location. Send your location with the vehicle details so the suitable arrangement can be confirmed.
What if I am not sure which key service I need?
Describe what works and what does not. Tell us whether the engine starts, whether remote buttons work, whether a working key remains, and whether the vehicle is currently locked. We can use those details to identify the most relevant service page and next step.
