Door Lock Issue?
 

Recently bought a 94 Camry XLE V6 with 344k miles on the odometer for cheap, still runs great , but I'm sure that's nothing compared to other Camrys out there. Anyways, so the drive side door lock doesn't turn when i put the key in, i have to go on the passenger side each time to unlock it. Also When I'm in the car (drivers side) and lock the doors , the passenger door doesn't lock, the 2 in the back do though. I've done quite a bit of stuff already on it already, just don't have the experience when it comes to taking door panels off, let alone the locks for the doors. Would be great to get some feedback on the parts i would need to fix it, thanks!

Try lubricating the drivers door lock.

Sometimes the electrical wiring for the power locks breaks typically where the wiring goes between the drivers door and chassis.
