There have been several discussions about why manufacturers only put keyed door handles on the passenger side. The consensus is pretty much that it was a safety issue, no one would have to stand in traffic to lock/unlock the door. Once the passenger door is unlocked they would reach through to unlock the driver's door. I don't know the setup of your 49 but my 38 has a standard door lock button that extends through the garnish molding. Pull up to unlock, push down to lock.
