Lost all the keys to your Hyundai? We provide professional mail in All Keys Lost key programming, immobilizer data recovery, EEPROM and MCU processing, SMARTRA programming, Smart Key preparation, BCM data processing, and immobilizer synchronization for supported Hyundai vehicles.

Hyundai has used several generations of transponder immobilizer, SMARTRA, Smart Key, proximity key, and push button start security systems.

Depending on the vehicle, immobilizer information may be stored in the SMARTRA module, Smart Key Unit, BCM, immobilizer control unit, ECM / PCM, or another security related module.

Because Hyundai immobilizer architecture varies by year, model, production date, ignition type, and market, VIN and module verification is required before sending modules for mail in service.

Provide your vehicle information and clear photographs of the requested module labels before shipping. Once compatibility is confirmed, remove and ship the requested module or modules. We will perform the supported immobilizer, EEPROM, Smart Key, or synchronization work and return the components ready for installation and any required final vehicle side registration.

Important Information

This is a mail in programming service for supported Hyundai applications.

Hyundai used multiple generations of immobilizer, SMARTRA, BCM, and Smart Key systems throughout production.

Required components may vary even between vehicles of the same model and similar model year.

Do not remove or ship modules until compatibility and the required components have been confirmed.

Buyer is responsible for removing and reinstalling all requested vehicle modules.

VIN and clear photographs of requested module labels are required when compatibility cannot be determined by year and model alone.

Some Hyundai All Keys Lost procedures require final key registration, synchronization, or initialization at the vehicle after the programmed modules and keys are returned.

Additional modules may be requested if required for immobilizer synchronization or security data recovery.

All modules must be packaged securely to prevent physical, moisture, and static damage during shipping.

Programming begins after all required components have been received and inspected.

No returns are accepted on programmed keys or programmed electronic modules.

Completed programming services are non refundable.

Buyer is responsible for confirming compatibility with their specific vehicle before purchasing.
