Push-button start key?
Smart-key procedures are vehicle-specific and often differ from
standard transponder-key programming.
Keyless entry and starting
What Is a Smart Proximity Car Key?
A smart key communicates with the vehicle while it remains nearby, allowing keyless entry and push-button starting without inserting a conventional key into the ignition.
Proximity Entry
Supported vehicles can unlock when an authorised key is detected near a door or handle sensor.
Encrypted Communication
The fob and vehicle exchange electronic security information before access or starting is authorised.
Emergency Key Blade
Many smart fobs contain a mechanical blade for emergency door access when electronic entry is unavailable.
The correct service depends on the situation
Do You Need a Spare, Replacement or All-Keys-Lost Smart Key?
Smart-key programming is not one universal procedure. Whether a working fob remains can significantly change the equipment, security access and time required.
Add a Spare Smart Key
An additional proximity fob can often be registered while the existing working key is available at the vehicle.
Spare car key serviceAll Smart Keys Lost
The replacement may require an all-keys-lost reset, encrypted access, module communication and an emergency blade originated from scratch.
Lost car key serviceDamaged or Unreliable Smart Key
Water damage, worn buttons, damaged cases or intermittent detection may require diagnosis before deciding whether the fob should be repaired or replaced.

Common Smart Key and Push-Start Problems
A replacement key may solve the problem, but some symptoms can also be caused by the vehicle rather than the fob.
- Vehicle displays “key not detected”
- Push-button start only works intermittently
- Remote buttons no longer lock or unlock
- Proximity entry works at some doors but not others
- Smart key has been wet, dropped or physically damaged
- Emergency-start position is required every time
- One smart key works but another is not recognised
- Vehicle battery has recently been flat or replaced

How Smart Key Replacement and Programming Works
The correct smart fob must match the exact vehicle system before programming begins.
1
Identify the Vehicle
Send the make, model, year, VIN when requested and a photo of the existing fob or dashboard message.
2
Confirm the Smart Key
Frequency, part type, button layout, emergency blade and security platform are checked before the key option is confirmed.
3
Register the Key
The fob is programmed or registered using the procedure required by the vehicle’s immobiliser and smart-access system.
4
Cut and Test
Starting, remote buttons, proximity detection and the emergency blade are checked where applicable.
More than remote-button programming
Advanced Smart Key Registration
A smart proximity key must be authorised by the vehicle’s security system before push-button starting and proximity functions will work.
Depending on the manufacturer and model year, the procedure may involve PIN or security access, immobiliser synchronisation, smart-system registration, ECU or BCM communication, encrypted data and manufacturer-specific reset procedures.
- Smart proximity fob registration
- Push-button start authorisation
- Remote lock and unlock synchronisation
- Emergency mechanical blade cutting
- Existing-key testing and supported lost-key removal
All existing smart keys should be present where possible. Some
procedures require every key to be registered again during the same
appointment.
Accurate smart-key quoting
What Affects the Cost of a Smart Car Key?
Smart-key pricing depends on the vehicle security platform, the key option and whether a working key remains.
1
Make, model and year
The same model can use different smart systems across its production range.
2
Spare or all keys lost
Adding a key is often different from resetting a vehicle with no working fob.
3
Key type and part option
Compatible aftermarket and genuine smart keys can differ in cost and availability.
4
Security procedure
Encrypted access, reset procedures and module work vary substantially.
5
Emergency blade
The mechanical override blade may need to be cut or originated separately.
6
Location and timing
Travel, access and urgent after-hours attendance affect the final quote.
Smart keys versus other key types
Is It a Smart Key, Remote Key or Transponder Key?
These terms are often mixed together, but they describe different functions and may require different replacement procedures.
Smart Proximity Key
Normally stays in a pocket or bag and allows proximity entry and push-button starting when detected by the vehicle.
Remote Transponder Key
Has lock and unlock buttons but generally still needs to be inserted into a conventional ignition to start the vehicle.
Transponder-Only Key
Contains an immobiliser chip for starting but may not include remote locking buttons or proximity functions.
Transponder key programmingVehicle compatibility
Smart Keys for Many Popular Vehicle Brands
Push-button start systems are common across Japanese, Korean, European and Australian-market vehicles, but procedures vary by platform and year.

Common questions
Smart Car Keys Gold Coast FAQ
What is the difference between a smart key and a transponder key?
A smart proximity key is normally detected while it remains in a pocket or bag and allows push-button starting. A standard transponder key usually needs to be inserted into the ignition, although both use electronic authorisation to start the vehicle.
Can smart proximity keys be programmed on-site?
Many supported smart-key systems can be programmed at the vehicle using mobile automotive locksmith equipment. Compatibility and procedure depend on the make, model, year and security system.
Can you add a spare smart key while one still works?
Often yes. Adding an additional smart key while a working key remains is usually a different procedure from replacing every key after all smart keys are lost.
Can you help when all smart keys are lost?
Many all-keys-lost smart-key situations can be completed, but the procedure may be considerably more complex and vehicle-specific than adding a spare key.
Why does my vehicle say key not detected?
A weak smart-key battery is one possible cause, but key-not-detected faults can also involve the vehicle battery, key electronics, antennas, receivers, immobiliser modules or communication faults. Diagnosis may be required before quoting a replacement key.
Should all existing smart keys be present for programming?
Yes, where possible. Some programming procedures require or benefit from having every existing smart key present, and all keys can then be tested before the job is completed.
Need a Smart Proximity Key?
Send the make, model, year, location, key photo and whether a working smart key remains so the correct option can be checked.
