FAQ - KEY-OVERRIDE appears to program but Toyota/Lexus will not remote-start

0 votes

The support article applies to remote car starter installations with either a KEY-OVERRIDE-SL, KEY-OVERRIDE-SL2 or a KEY-OVERRIDE-ALL on Toyota or Lexus vehicles.

 

Problem:

The KEY-OVERRIDE Bypass module appears to program with Toyota and Lexus vehicles, but the vehicle will fail to remote start. When remote starting the vehicle the LED on the KEY-OVERRIDE will flash rapidly instead of staying solid.

In some rare cases the KEY-OVERRIDE will fail to synchronize itself with the rolling transponder code during programming. The key being used uses a transponder code that the KEY-OVERRIDE module does not recognize. This situation will only occur during the initial installation of the KEY-OVERRIDE Bypass module and will not occur at any time afterwards.

 

Solution:

Use a valet key and re-program the KEY-OVERRIDE Bypass module.
Important: Do not attempt to reprogram the KEY-OVERRIDE module a second time using the same key. If this happens the KEY-OVERRIDE module will become locked and a new KEY-OVERRIDE module will need to be used to program using the valet key.

Note: The KEY-OVERRIDE Bypass module will allow you to program it two times before it becomes locked. Once it is locked you cannot unlock it by re-flashing the firmware, it must be re-flashed at the factory. This is a safety feature that prevents the module from being learned to multiple vehicles.
