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

Honda has used several generations of immobilizer and Smart Key technology. Depending on the vehicle, immobilizer data may be stored in the Immobilizer Control Unit, Immobilizer Keyless Control Unit, MICU / BCM, Smart Power Control Unit, Keyless Access Unit, ECM / PCM, or another security related module.

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

Simply provide your vehicle information and photographs of the module labels. Once compatibility is confirmed, remove and ship the requested module or modules. We will perform the supported immobilizer, EEPROM, key preparation, or synchronization work and return the components ready for installation and any required final vehicle side registration.

Mail In Requirements

Honda security architecture becomes increasingly vehicle specific in this generation.

Depending on application, security information may involve:

• Keyless Access Control Unit

• Smart Power Control Unit

• BCM / MICU

• Immobilizer related module

• ECM / PCM

Not every vehicle in this year range can be completed as a stand alone mail in programming job.

Compatibility must be confirmed before purchase.

Provide:

• VIN

• Year

• Model

• Engine

• Mechanical Ignition or Push Button Start

• Photograph of the current key type if available

• Clear photographs of requested module labels

Emergency Key Cutting

For vehicles equipped with an emergency mechanical blade, send:

• One working emergency blade

OR

• One driver's door lock cylinder

If neither is supplied, the new emergency blade will be returned uncut.

Late Model Honda Smart Key Systems

Approximately 2020 to Present

Common Models

• Honda Accord

• Honda Civic

• Honda CR V

• Honda HR V

• Honda Odyssey

• Honda Passport

• Honda Pilot

• Honda Prologue

• Honda Ridgeline

Late model Honda vehicles use newer security authentication, Smart Key, BCM, gateway, and immobilizer architectures.

Some applications can be handled with professional aftermarket immobilizer equipment, while others require additional vehicle side security access or online procedures.

Do not remove or mail modules from a late model Honda until compatibility has been confirmed.

Before purchasing, provide:

• VIN

• Year

• Model

• Engine

• Push Button Start or Mechanical Ignition

• Clear photographs of requested module labels

Late model services are accepted on a case by case basis.

Services Included

Depending on vehicle and immobilizer system, services may include:

• All Keys Lost recovery

• Honda transponder key preparation

• Honda Smart Key preparation

Mechanical & Emergency Key Cutting

Mechanical key and emergency blade cutting is available with this service.

If you would like the replacement key cut before it is returned, send:

• One working mechanical key or emergency blade

OR

• The driver's door lock cylinder

For an All Keys Lost vehicle, the supplied door lock cylinder can be decoded to determine the mechanical key cut.

If neither is supplied, your replacement key will be returned with an uncut mechanical or emergency blade.

Important Information

This is a mail in programming service for supported applications.

Honda used multiple immobilizer systems and module configurations throughout production.

The required module for one Honda Accord, Civic, CR V, Pilot, or Odyssey may not be the same as another vehicle of a similar 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 modules.

Providing the VIN and clear photographs of module labels before shipping is required for applications where the correct system cannot be identified by year and model alone.

Some Honda All Keys Lost procedures require final registration or synchronization at the vehicle after the programmed key or modules 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 components.

Completed programming services are non refundable.

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