    Exclamation Rqnge Rover L322 Immobiliser issues after battery disconnect

    My 2005 Range Rover recent went to my local shop (not dealer), for some basic work, which required the battery to be disconnected.
    Now the immobiliser will not allow the key to turn in the ignition fire-inserted after removal.
    The only way I can get the key to free up in the ignition is to disconnect the batter negative for 10 mins and then reconnect.

    I can drive it now of course - so long as I don't take the key out of the ignition a but I can't lock it, so now there is a security issue.

    Any help would be appreciated.

    Thanks

    Welcome to the forum
    Maybe I don't understand business in Qatar, but I would think that this is a problem that the shop needs to resolve not this group. Take it back to the shop with the expectation that they fix it or pay the dealer to fix it.

    The shop is mainly specialised in Mercs and BMW (with my L322 being based on the X5 platform) and they are still trying to figure it out, but I needed the car back to use while they do so. they have the diagnostic computer and subscription to Land Rover (TATA). To them it is either the immobiliser or the ignition. To me it seems like a pairing issue and the system is not retaining the "memory" of the keys. I suspect that the immobilise or the ECU needs to be refreshed but my shop does not have the capability. If you go to the dealer here in Qatar, you not only "lose" your car for weeks, but you may as well hand over your bank account. When I bought it second hand, I thought I would try them to see how good they were. They charged me 1800 pounds for a 120k kilometre standard service (nothing special found or changed), and if I had not stopped them, they would have replaced the discs instead of skimming them, as it was not their policy to skim. They wanted to charge me almost 200 pounds just to straighten a small bend in the front number plate (they were going to change the entire plate holder, which had nothing wrong with it). I opened up the holder and straightened the plate myself in two minutes - for free.

    I don't have a problem to pay to the dealer to have it fixed, and maybe I am reading the reply wrong (so sorry in advance if that is the case), but I thought the purpose of the forum was to share experience and advice so as to avoid being ripped off and to have fun keeping our RR running. What I am hoping for here, if not a solution that I can do, is to have the problem narrowed down based on the experiences of other forum members, before I have to submit to the dealer and get ripped off for expensive change outs that I don't need, with a labour charge of 40 pounds an hour.

    You will find that it is the immobilizer ECU that has gone Bad, I think it is located in the rear right behind the Fuse panel in the Trunk. I had the same issue it turned out to be a bunch of Transistors that had fried. But the unit was replaced as they cover these things in a Potting compound to prevent vibration and moisture from making them fail. The Keys will need to be reprogrammed for the ECU that requires the T4 computer at a Dealer.
