I'm not too sure what you mean? Did you replace the whole assembly because the PK2 decoder is many times seperate from the ignition lock. Also, when you properly replace the decoder or whole assembly you still have to learn it to the car because it'll have a new code versus what the car already has.

The 555t bypass only sends out the bypassed coded when the blue wire(I think it's blue, it's been a long time since I've sold DEI stuff) sees a ground pulse during remote starting. Now, you could take that pulse wire and hook it up to the keysense wire of the car as long as you are sure you got the right code. The keysense wire goes to ground when you insert the key into the ignition. If you were just to keep the pulse wire grounded it'd work but may run down the battery too quick because it'd be on all the time.
