So story goes, a Friday I was having problems with my indicators which I have determined is the relay. Anyway ordered one which should arrive Monday so solve that problem. However once I took the old relay out to determine that it was the fault I couldn't start my car due to it not recognising the key 
.
So tried redoing the process of locking it all up then unlocking and starting the car... No luck there
.
Tried the spare key... No luck again.
Tried both processes lots of times... Finally it worked
.
Worked fine yesterday so I assumed all was well again.
Got in the car home from work today same thing happened as Friday.
Surely the key can't need recoding as it recognises it eventually. Then both keys (normal and spare) work fine, could it just be due to the relay? Should I be looking for something else? Really need my car this week if possible else I'll have to book it in with an auto-electrician.
