Spare smart keys
Add a compatible spare smart key for supported vehicles.
SMART KEYS
Smart Key Programming
Programming for supported proximity, push-start and smart-key vehicle systems, including spare and replacement smart keys.
Smart keys use proximity and immobilizer technology rather than a simple mechanical key alone. Locksmith.lk provides programming for supported smart-key vehicles, including spare-key additions, compatible replacement keys and selected all-keys-lost situations.
Replacement smart keys
Program supported replacement proximity keys.
Push-start vehicles
Programming for compatible push-button-start systems.
All-keys-lost assessment
Vehicle-specific options when no working smart key remains.
Emergency blade cutting
Cut supported mechanical emergency blades where required.
Function testing
Check starting, proximity and supported lock/unlock functions after programming.
SERVICE GUIDE
Smart-Key Compatibility Comes First
Push-start and proximity keys can look identical while using different frequencies, boards, part numbers or regional specifications. That is why choosing a smart key by appearance alone is risky. We identify the vehicle and existing key system before confirming a compatible option.
Programming registers the supported smart key with the vehicle. Depending on the system, an emergency mechanical blade may also need to be cut. All-keys-lost situations can require a different procedure from simply adding a spare.
Spare Smart Key
If you still have a working smart key, making a spare is the lower-disruption option. We confirm compatibility, prepare any emergency blade and program the supported proximity and starting functions.
Lost Smart Key
If the only smart key is lost, send the exact vehicle details before purchasing anything. The programming route, required key and security procedure can be different from a spare-key addition.
HOW IT WORKS
Simple, Clear Service Process
Identify the vehicle
Send make, model, year and whether the vehicle uses push-button start.
Identify the key
Photos, FCC/board details or the existing key may be needed to confirm compatibility.
Program the smart key
The compatible key is registered using the supported procedure.
Test all functions
Starting, proximity and remote functions are checked where supported.
GOOD TO KNOW
Smart-Key Functions We Check
After supported programming, we check the functions available to test: vehicle recognition, push-button starting, proximity entry and remote lock/unlock where applicable.
A weak key battery can create intermittent proximity or remote symptoms without the key actually losing programming. Battery and key condition should be checked before assuming reprogramming is necessary.
An emergency blade is easy to overlook because it may remain hidden inside the smart-key housing. Cutting this blade gives you a mechanical access option on supported vehicles when electronic entry is unavailable.
SMART KEY PROGRAMMING GUIDE
Smart Key Programming and Compatibility
Proximity and push-button-start keys combine several functions in one device. Exact compatibility matters because keys that look the same can use different electronics, frequencies and vehicle-security configurations.
What a Smart Key Does
A smart key can support passive entry, push-button starting, remote locking and an emergency mechanical blade. These functions are related but can fail separately.
Tell us whether the vehicle detects the key inside the cabin, whether push-button start works, and whether lock/unlock buttons still operate.
Part Numbers and Compatibility
Appearance alone is not enough to select a replacement smart key. Frequency, board type, part number, market specification and vehicle year can matter.
Send photos and identifiers from an existing key where available before purchasing a replacement. An incompatible key may not be programmable even if the case looks identical.
Adding a Spare Smart Key
Making a spare while a working smart key remains is generally preferable to waiting until all keys are lost. Bring the working key and vehicle details so the supported procedure can be checked.
The emergency blade may also need cutting even though normal operation is electronic.
All Smart Keys Lost
All-keys-lost smart-key work can require a different security procedure from adding a spare. Tell us immediately if no working smart key remains.
Ownership/authorization must be confirmed and support depends on the specific vehicle system and equipment required.
Battery vs. Programming Problems
A weak coin-cell battery, damaged buttons or a vehicle-side detection issue can imitate a programming problem. Reprogramming is not the first answer to every “key not detected” message.
Where practical, we distinguish battery, hardware, compatibility and programming issues before recommending replacement.
Testing After Programming
Supported proximity entry, push-button starting, remote buttons and emergency-blade operation should be checked after the job. A single successful engine start does not test every smart-key function.
If one function remains faulty, we explain whether further key-side or vehicle-side diagnosis is appropriate.
Shop and Mobile Options
Spare-key identification and preparation may be convenient at the Pannipitiya shop. Selected vehicle-side programming and all-keys-lost work may be suitable for mobile service.
Send the vehicle details and location to 070 625 0000 so we can confirm availability and the practical option.

The suitable location depends on the job. Contact us with the vehicle and key details first so we can confirm the compatible key, programming support and whether mobile service is appropriate.
COMMON QUESTIONS
Smart Key Programming FAQs
Can you add a second smart key?+
For many supported vehicles, yes. Send the vehicle details and a photo of the existing key.
Can you program a smart key if all keys are lost?+
It is possible on selected vehicles, but procedures and required equipment vary significantly by make, model and year.
Can I buy any smart key online and program it?+
No. Smart keys can differ by frequency, board, part number and region even when the case looks identical. Compatibility should be checked first.
Do smart keys need cutting?+
Many smart keys contain an emergency mechanical blade, which may need cutting even though normal starting is keyless.
