I've just bought an E280 (1995) and it has remote central locking.
I don't know much about these cars but has it got an alarm on it as standard (if it has i haven't heard it so how can i activate it?) or will i require one.
If it needs an alarm then can it be installed alongside the central locking i.e all on the one remote or would it require a seperate remote meaning i have to carry two about?

thanks and hello as i'm a n00bie!

p.s If this is in the wrong forum i apologise.
