Scoot, I suppose if you can get hold of the key to match the new handle. Just have to lumber around the additional key unless it coincidentally has exactly the same associated security code. My scenario, which I think is probably more likely, is that you land yourself lumbered with just a pile of extra handles from a breakers yard, all with no keys. My bmw 2002 had a passengers lock which couldn't be locked and it drove me nuts over the 5 years I owned it. Suppose you could always install a central locking system to get around the issue.
