Hi all,

I need help! Not in a medical sense but in I have recently brought a disco 2 and now the issues are starting.
When I first brought her, she was making a horrible noise. Turned out to be the front prop shaft. This has been repaired, but now she wants to start causing issues with the central logging and the immobilizer struggling to disengage. (I don't think for a minute that this is related to the new prop shaft before someone says it!)
So, when I first brought her, she would fire up on the turn of the key by canceling the immobilizer with the key 'land rover' button. She locked and unlocked with the key fob. Now she has stopped locking and unlocking with fob. Fob battery has been changed.
There feels like there is no lock in the master key lock in the driver door as the lock just spins round. The doors will lock and unlock on the rocker switch on the dash, but not with the key or the buttons so to me that has ruled out the central locking fuse.
Sometimes she will start first time and cancel the Immobilier first time. Other times, normally when people are watching or I have a car full of kids i will have to turn the key round to the starting position, hold it there, whilst pushing the key in and rapidly pressing the land rover button before the Immobilier finally cancels.
Once started i can actually remove the key from the ignition barrel and she keeps running.
Has anyone got any ideas when the issue could be, or has anyone had a simulier experience.
Kind regards,
BigMac1

 

I see this is your first post. Welcome to the forum! And good job catching the front driveshaft before it grenaded and put a hole in the transmission.

Please, please let us know where you are located. There may be someone on this forum nearby who can help you out in a pinch, either now or down the road.

I know you wrote about the immobilizer / keyless entry handset, but let's start with the key in the lock.

The key spinning in the door lock cylinder is a well-known problem. There is a rod about 3-4" long that connects the lock cylinder into which the key is inserted to the actual lock mechanism in the door lock actuator. From the factory they were made of a cheap "pot metal" and are, as I said, known to break.

When this happened in my truck many years ago I fashioned a replacement from a 20d nail.

Now, a replacement is available from forum member abran. In my opinion it's over-engineered, but I'm fully confident it will never break. The repair is tedious but not difficult.

Now back to the "immobilizer sensor". The symptoms you describe are indeed unusual.

Pressing the button on the handset while turning the key has nothing to do with starting the truck (other than coincidence, perhaps). And, you certainly shouldn't be able to remove the key with the truck running. Sounds like you may need a replacement ignition lock cylinder.
