Module needs to be able to detect an UNLOCK command from a remote (either the original remote or an RF-KIT) or takeover will not be available. That's the security feature. No unlock = module thinks it's a thief and shuts down the car.
-
US builds: If using 3xLock start, take over is not available since the OEM remote, once the car is started, is undetectable for the EVO.
-
Canadian builds: If using 3xLock start on a Canadian build, take over will be functional since the factory remotes are still able to be detected
If using an RF-KIT (aftermarket remotes), takeover will always work when unlocking the car with the aftermarket remote.
Was there an upgrade that really makes it work or is this just a mistake in the database?
The upgrade is more of a, there is some extra wiring required, similar to US based Toyota vehicles (they share similar technologies).
