My remote locks the doors, but doesn't unlock them?

If you're finding it difficult to service/repair your car, get one of those online manuals. You'll not have to wait for others to answer, or rely on mechanics and all.
Plus i know a website that sells very cheap but very very good manuals online, without expiry i.e. for lifetime.
try reliable-store com..
also try manualslife
these two are very good

1) Key turns but dose not unlock door. This means that the rod that goes to the back of the lock has came off. This also means that is the reason door is not unlocking with the remote as it pops the lock rod inside the door which pushes the lock open.
2) Key does not turn lock at all but works passengers side door. This means that the locks has been changed in the door, but that doesn't sound like the problem as you say the remote doesn't open the drivers side door so more than likely the rod has came off the back of the lock

The power door lock electric actuator motor is defective most likely. You will need to pull the door panel off and test it with a volt meter for power and ground when the power locks are actuated, if the system is powering up the lock motor but it doesn't move the rod then replace it,.

how do I reset one of two keys that the unlock,lock,trunck does't work but the key turns the engine over.

There is a fuse box under the right rear seat cushion behind the driver. In that box is a 10 amp mini fuse marked "TRUNK DR RELEASE". That is the fuse that powers your remote receiver. If that fuse is good, the receiver may have failed. To remove the seat cushion, pull the front of the cushion up and then forward.

Pull the switch panel and verify you have power to the panel first.

Does the driver side door lock and unlock when you press the lock/unlock button on the handle?

If it doesn't work inside either, then either the wiring is damaged/shorted, the solenoid may be bad or the lock may be jammed.

If the lock is jammed then it will be difficult to lock and unlock with the key as well.

Any of those three problems will require you to take the door panel off and inspect behind it.

If it will not unlock with the key, replace the latch/lock.

I would take it back and tell them they need to fix it. it sounds like a wire for the lock/unlock may of fallen off or there is a problem with the remote stare module. wires tend to fall off if all the used were crimp connectors and didn't solder the wires together.
