Smart key programming for push-start and proximity vehicles
Smart keys allow functions such as push-button starting, proximity entry and keyless locking without inserting a conventional key into the ignition. Programming a replacement smart key requires the correct electronic key for the exact vehicle system. Similar-looking remotes can use different frequencies, boards and security data, so visual appearance alone is not enough to confirm compatibility.
We assess additional smart keys, compatible replacement keys and supported all-keys-lost enquiries. Send the vehicle make, model, year and clear photos of the current smart key before buying or booking whenever possible.
Adding a second smart key
If one smart key still works, tell us. An additional-key job can be more straightforward to identify because the existing key provides a useful reference. Photograph the front and back, and include any visible part or board number. If the vehicle was imported, the market specification can also matter.
“Key not detected” does not always mean programming
A push-start vehicle can display a key-not-detected warning for several reasons. The fob battery may be weak, the smart key may be damaged, another working key may reveal that the fault is isolated to one fob, or the vehicle itself may have a related electrical issue. Before assuming the key has lost programming, tell us whether the problem is constant or intermittent and whether a second key behaves normally.
All smart keys lost
When every smart key is lost, state that clearly. The workflow can be substantially different from adding a spare and may involve vehicle access, key identification and additional security procedures. Support depends on the exact model and year, so we check the job before dispatch.
Buying a replacement smart key
Do not order solely by shell shape. A key can fit the same case while containing incompatible electronics. If you already purchased one, send its labels, part numbers, frequency information and photos. We can assess the information provided, but programming cannot correct incompatible hardware.
Smart key, remote and emergency blade
A smart key can contain several functions in one unit. Proximity detection, remote buttons, immobilizer authorization and the emergency mechanical blade are related to the same key but are not necessarily the same repair or programming task. Tell us which function has failed. That helps us avoid treating a remote-button problem as a full smart-key programming job.
Mobile smart key service
Mobile availability depends on the vehicle, key situation and location. Send the make, model, year, location, key photos and whether the vehicle currently starts. If you have a replacement key, include its information too. We use those details to check the likely system before confirming an appointment.
Smart key programming questions
Can you program a smart key that looks identical to mine?
Appearance is not enough. Electronic compatibility must be checked.
Should I replace the fob battery first?
If the symptoms suggest a weak battery, that is a sensible basic check, but a new battery will not repair damaged electronics or make an incompatible key work.
Can I get a spare while one smart key works?
For supported vehicles, an additional smart-key enquiry can be assessed from the exact vehicle and existing-key details.
What information is most useful?
Make, model, year, location, current key photos, number of working keys and details of any replacement smart key already purchased.
Request a smart key compatibility check
Send the vehicle and key information before arranging the job. We will check the likely smart-key system and confirm the next step rather than guessing from the shape of the remote.
Need help with your vehicle key?
Send the vehicle make, model, year, your location and whether you still have a working key. We can then check compatibility and availability.
