After fiddling with OVP relay it would sometime also light ABS light. Obtained relay today and has seemed to cure both lights. Hope this info helps the next person. New relay has two fuses.

I am going to try unplugging the two wires on the side of the lock housing when I have time to see if it stops the buzzer.

I am guessing the part of the switch moves when the key is inserted and broken and keeping the lock cylinder in the housing even when I try use the inserted 2mm wire.
