All cars with a single line system can be unlocked from either front door or the trunk.
Untrue, as there is an early 126 system that still only operated from the driver's door, yet was single-line. It's nasty, btw, that pump is poorly-designed and fragile. I don't know if this same system was ever in other cars of that vintage (107, 201), I do know it's _not_ in a 123. -- Jim
