Hi its a c200 esprite, the problem I had was the remote key opened all four doors but wouldnt open the boot then it would lock the car. The car started fine to it for a run to get batteries for the key as thought they were running low and not sending enough signal but that didnt do anything checked all the fuses apart from the ones in the boot as couldnt get to them. The alarm kept going off when you opened doors but it was very quiet. Have you got any idea what could be wrong or caused this to happen?
