Re Using Locked Toyota OEM Smart Keys with Tango on the AAAA Immobilizer System

Re Using Locked Toyota OEM Smart Keys with Tango on the AAAA Immobilizer System

Edward Kowalik |

We decided to make a video to show how used locked Toyota Lexus keys on the new immobilizer system starting around 2019+ can be reused. 

For the longest time, the Toyota and Lexus keys that scan with Page 4 line of data as AAAA, have been useless. With some clever work from a few companies now, you can program an emulator to the vehicle and transfer the sync data to a locked Toyota / Lexus smart key.

This includes a multitude of keys such as but not limited to

  • HYQ14FBC RAV4, Highlander 
  • HYQ14FLA RAV4, Highlander, 4Runner
  • HYQ14FBF Lexus
  • HYQ14FBZ Lexus
  • HYQ14FBE Avalon

The process is quite simple as shown in the video we uploaded. Following the steps under the Tango SLK-07 screen, reusing a locked key is a breeze. Gone are the days of needing to purchase $130 + OEM brand new keys for doing add key jobs when the customer needs OEM. Even aftermarket keys are running around $45 in the current market! We sell the locked Toyota keys for around the $40 range depending on current market values.
