EoneBoss / Key Programming Devices

The EoneBoss TLK1 is a professional solution designed to reuse locked Toyota and Lexus smart keys that normally cannot be reset or unlocked using traditional methods. Instead of unlocking, refreshing, or damaging the key, TLK1 uses innovative non-destructive technology to directly match and reactivate locked keys, significantly reducing replacement costs and saving time.

This makes TLK1 an ideal tool for professional locksmiths and automotive technicians working with Toyota/Lexus systems.

What Makes TLK1 Different

When a used Toyota/Lexus key becomes locked, standard workflows require unlocking and resetting the key to a blank state. However, certain encrypted key types (8A, AA, BA, B9, B8) cannot be refreshed due to security limitations.

TLK1 solves this problem by:

Reusing the locked key without unlocking
Preserving the original key hardware
Completing the process safely, quickly, and reliably

Core Advantages

High Compatibility: Works with any brand or model of diagnostic or programming device. No hardware restrictions.
Non-Destructive Operation: No opening, welding, unlocking, or physical modification of the key. The original key remains fully intact.
Convenient & Efficient: Simple, standardized operation. No advanced technical training required.
Cost-Effective Solution: Reuse locked keys instead of replacing them with new OEM smart keys.
Customizable Language: Default language is English. Other languages available upon request.

How TLK1 Works (4-Step Process)

Step 1 – Simulate Key Generation
Place the locked or accidentally deleted key on the TLK1 sensing area and press the button.
TLK1 reads the secure identifier (such as key ID) and simulates a matching key internally.

Step 2 – Match to Vehicle
Use TLK1 as a temporary replacement key during the vehicle matching process.
The device writes key information into the vehicle while securely storing related data.

Step 3 – Write-Back Operation
After data collection, TLK1 writes the complete key information back to the original locked key, reactivating it.

Step 4 – Final Confirmation
Test the key to confirm all functions work correctly. The key is now fully reused and operational.
