Can't get car locked

You may have a button on the door that says lock and it may lock everything fromworking. It won't say door lock it's usually to lock the power windows and doors from anyone using it inside the vehicle. You might try resetting the remote or checkingthe battery in it.

There are two relays at the "d" pillar. "A" pillar is the post by the windshield then b-c-d so on so it might be by the tailgate. Andyhow there is one for drivers door unlock a nd another for all door unlocks. That may be bad you could try replacing it with one from one of your other ones if they are the same. If the door looks work, the you just need a relay. If it's the receiver for the remotet those are around $125 but there is a microporcessor that can be bad and I can't find a price for that.
