I have a 2002 Camry LE with about 51K miles on it. Has had a problem with charcoal canister, but was fixed without problem. Now the driver's side door lock is sticking. When I activate the keyless lock system, all the door locks engage except the driver's side. The alarm will engage and will go off if you open the unlocked driver's door. I can lock it with the key so it's not a mechanical issue with the lock itself. I used a lubricant in the locking mechanism (inside and out) without success. I checked the fuses and they seemed intact.

Any ideas?

Possibly the power lock motor going bad? Also maybe a loose electrical connector to the motor inside the drivers side door.
