Alarm/immobiliser

[Mark Adams]

After recently purchasing a freelander 1.8 1998, I locked the car via the key fob and all was well for a a couple of minutes (all the doors locked and the dash light flashed). I then walked away and the alarm went off, nothing was anywhere near the car to set it off so I can only assume it is a faulty sensor? This happens everytime I lock the car.

I know nothing about the security systems on these but I guess that the PIR is picking up movement that does not exist?

Any advice on how to resolve the problem?

It's not PIR, it's seperate volumetric and "perimetric" (ie doors) systems.

If you key lock the car (double twist of the key) and you dont have the problem, you've isolated the problem to the volumetric system.

I notice that only the drivers door has a key lock, if I use this to lock the door it only locks the drivers door (not all doors). I guess this is another problem.

As Blippie said, turn the key twice to lock all the doors

I now understand what he meant, I have now tried double locking the car and when locked using this method all is fine and the alarm does not sound.

So with this in mind does anyone know what may need adjusting/replacing? Is it going to be straight forward?
