Well I had the most amazing stroke of luck. I contacted Brand Hatch Morgan to inquire about key replacement and was informed that they had been called by someone who had found a set of keys with a BHM fob. It seems that I had dropped the keys outside my house and somehow they go wedged underneath the car probably on the silencer. I had then traveled some 20 miles from home before they fell off. A kind sole found them and was good enough to call the number on the fob, I picked them up from his house on Tuesday. I still cannot believe my luck.
