For years, locksmiths and auto technicians have faced a frustrating reality with Toyota and Lexus vehicles: once a smart key is “locked” (accidentally deleted from the car, failed programming, or removed from the ECU), it’s usually considered dead. You either throw it away or send it to a Tango/Yablochkov specialist for expensive recovery. That just changed. Enter the TLK1 by EOneBoss – a tiny, one-button device that can take a completely locked Toyota/Lexus proximity smart key and turn it back into a fully functional key in under two minutes, often cheaper than buying a new aftermarket key.
Revolutionary TLK1 from EOneBoss: Reuse Locked Toyota & Lexus Smart Keys in Minutes – No Tango Needed!
We put the TLK1 through its paces on a Toyota hybrid with a locked OEM smart key that was showing “not recognized” by the car.
Here’s exactly what happened:
- Placed the locked smart key near the TLK1 sensing area.
- Pressed the single button on the TLK1.
- The device instantly read the locked key’s data and generated a temporary “emulator” inside itself.
- Went through the normal Toyota/Lexus “add new key” procedure in the car using the TLK1 as if it were a brand-new key.
- After the car accepted the TLK1 as a valid new key, they placed the original locked key back onto the TLK1 and pressed the button again.
- The TLK1 wrote the new, valid key data back onto the originally locked key.
Result:
The once-dead key now starts the car perfectly. The original working key still works too (no keys were erased).
Total time: about 90 seconds of actual TLK1 interaction.
Why EoneBoss TLK1 Changes Everything?
- No more throwing away $50–$150 locked OEM keys you find on eBay or pull from wrecks.
- No Tango, no Yablochkov, no expensive bench programming.
- No Lonsdor, Autel, or Xhorse key tool required for the reuse part.
- Works on many 2010–2022+ Toyota/Lexus proximity systems (exact model list is expanding fast).
- The TLK1 wipes itself automatically after use – zero security risk.
Two Versions Available:
OneBoss released the TLK1 in two flavors (first 200 units):
With built-in rechargeable battery (100 units) – completely wireless.
No battery version (100 units) – just plug in any USB-C power bank or even your programming tool (AutoProPAD, OBDStar, etc.) via USB-C to power it. Works exactly the same.
Both versions are identical in function; only the power source differs.
