    Hi just bought a WJ.

    I am having a problem where the car wont lock with the key less remote but will unlock. The driver side panel works perfect for locking and unlocking of the 4 passenger doors. Its just with the remote that it wont lock.

    Might be related, the hatch (hatch door and window) wont lock with the door panel controls or with the remote. It just stays open.

    Any ideas?

    I would suggest checking for a wire break where the door goes into the body, over the past 19 years I would think that your door has been opened and closed quite a few times. Although that is just a place to start looking.

    Welcome @ruanpotgieter95 ....Have you tried replacing the battery? Have you tried the other remote? I have a similar situation with a '97 Avalon: remote will open doors and/or trunk but won't lock the doors. The interior unlock/lock button works perfectly so in my case I suspect 1) defective remote or weak battery, 2) receiver issues.

    Thanks for the quick replies.

    Will look into checking the wires this weekend. If that's not the case I would also suspect the remote. I have changed the battery but doesn't make a difference. Will also check the back hatch close sensors. Maybe they are faulty. That will explain the back hatch not locking from the door panel and I read somewhere that if all your doors are not properly closed, then the car won't lock by remote.

    So my guess is that the computer sees that hatch as still open so the car won't lock by remote or lock the hatch.

    Yup...the system probably won't lock if the rear latch is detected to be an issue

    Will look into maybe trying to fix that this weekend. Hopefully this will resolve the issue.
