Can you clarify, are you after the MB keyless-go where you do not have to touch the key when entering/leaving the car (just have to carry the key with you) or are you after remote controlled central door locks, where you press a button on your car key to lock and unlock all doors (no need to use the mechanical key)?
The first option is generally considered too complicated as a retrofit (actually unlikely ever existed for a 1995 C-class car even from the factory), several after market systems exist for the second one and that option would be feasible. These are often combined with burglar alarms.
Sorry but I do not remember if a -95 car had remote control for door locks, perhaps you already have this.
