My 2006 Scion tC with a key-less push button start. This was accomplished by designing and building a RFID reader under the cup holder that detects the presence of the RFID tag in the key fob.
After the RFID reader detects the tag inside the key fob, a signal is sent to an actuator in the steering column. Which in turn releases the steering lock mechanism in the lock cylinder, allowing free movement of the steering wheel.
I know, it’s a lot of work for a simple push button start, but it was the only way to safely bypass the factory Scion security controls and still maintain functionality of the security system to prevent theft.
Thanks for watching
