I have bought a car which has the SEA-8081 system. It was working ok until I was poking around under the dash and 'flipped' the valet switch. The complication is that I have two valet switches - one on either side under the dash and I find the manual too complicated. The Extension LED is now continually flashing (after I tried various attempts at pressing buttons on the remote!). How do I get back to normality?
