When i open the doors with the key button, the car is open, but when i pull on the handle on the passenger side door, the button goes down and locks, just on that side

How are you trying to open the door , button on key fob ? With this system you can pull up on the drivers handle an it activates Antennas in the external side door handles (C30/C70 front doors, S40/V50 rear doors)

Antennas in the passenger compartment and cargo compartment

An antenna in the rear bumper

Quick lock motors in the lock units in the side doors

The remote keyless entry (RKE) receiver receives a signal from the key

The switch in the clutch pedal (manual transmissions) or a signal from the brake pedal switch via the central electronic module (CEM) (automatic transmissions)

Key-in switch.

Switch in door handle and lock button on handle .
If a door handle is pulled outward, a switch closes that wakes up the system and activates the antennas in the handles on the side where the handle has been pulled out. If a valid key is within a radius of approx. 1.5 metres from the handle, the relevant door will open and the vehicle will unlock one or several doors. Which doors are unlocked depends on the settings for the system. The vehicle can also be unlocked if the handle is affected on the tailgate.

Take off inside door panel...check rod from lock to handle. May have bad handle.

this is not a problem, it is a feature. its purpose is to try and make it harder to lock your keys in your car. try this: with the door open, pull the inner door handle like you are opening the door. with the handle pulled, lock the door. it will lock.

adjust the actuator rod movement to short

If the passenger door has not been opened for some weeks or months, or in icy weather, it is possible that the rubber seals around the door frame will cause the door to appear 'stuck' fast - in this case, a bit of extra force from inside the car whilst pulling on the interior door handle should cause the door to open. Failing that, if the car has electrically operated central locking, when the key fob is pressed to deactivate the central locking does the door lock on the passenger side work as expected? Try unlocking the passenger door with a key, and or pull the door lock button upwards to ensure that the lock has been deactivated. Check for blown fuses.

It is most likely a rod has fallen off inside the door. You may have to use a coat-hanger to read down inside and pull back on door latch to open it up.
Then after it is opened, remove screws on inner door panel, remove window/lock controls, take a big flat-head screwdriver and gently pry next to the plastic tabs holding on door panel. Remove door panel and put window back on track , and replace or reattach door handle rods.

I have a 2002 land rover discovery and my passenger front door won't unlock with the interior lock button on the dash or with the key fob. The only way to unlock the door is to pull the handle on the inside of the door. Is the actuator bad?

Please help

if you can open the door its the lock actuator from handle to lock that may be off need to pull off the door trim panel /please rrate my response thank you very much

This is only a possible solution to your problem. I had similar problem with my car. It turned out that the window locking toggle on the driver door not only prevented the other windows from being opened by passengers but also controlled the door locks. When I unlocked the window control I was able to unlock the door. Another possibility is the armature inside the door has come off the locking mechanism.
