    Hi all,

    First posting from a newbie (although I've lurked for a little while).

    BMW 520i 1995. I've lost my immobiliser key fob so can't start the car. I can get in with the key but the alarm goes off. I still have the spare fob but that doesn't work either, even with new batteries in it. The little red LED doesn't light so I'm assuming it's kaputt. What are my options?

    Can I get a new non-BMW immoboliser system fitted?

    Can I simply bypass/remove the BMW system?

    Do I have to fork out £150 on a car recovery vehicle to take it to a BMW dealer who will charge another £150 for a new fob plus an additional £200 to programme it? I can't be the first person to find himself in this position?

    Finally, can anyone recommend someone mobile who could do the work in the south east London area?

    Thanks guys.

    An E34 BTW should it be important.

    Few things you didn't mention mate, isit a standard BMW alarm?

    bceause if it is then you've got nowt to worry about because they don't have an immobiliser built in, they only protect doors and shock sensor as an axtra option.

    What you need to do is go down to the dealers with your logbook and something else with your address on it and they'll order you another key for the car.

    Forogt to say if its an aftermarket alarm there easy enough to bypass by following the wires up, could be time consuming if its a 2 point or 3 point imobilisation system and if the installer did their work properly.

    Thanks for the info. It is the original BMW alarm. I did take the car details with me but that option was never offered. Are you sure they'll do that? The car is registered as a 95 although it's a 94 built car. The only thing is they don't list the key fobs as a spare anymore (apparently). I've got the key. It's the immobiliser fob I'm missing.

    What fob did you have mate? The one with the snipped corner and do you know the alarm model you have?

    Hmm I don't think you car had the EWS with it being a '94 model so your alarm could have an immobiliser built in. Best of just removing the whole thing mate and rejoining the wires where they've been split to make an immoblisation circuit.

    And the key fobs are available, if you've got the 3g-ews system you can programe it yourself (requires removal of glovebox), but if you've got the 3t-ews system then its only programmable by someone with a sigma machine ie dealers or a sigma specialist

    keyfobs are around £40 from dealers or cheaper on ebay.

    As near as I can tell you, I haven't got a clue. It's a separate immobiliser key fob from the key. It's a hard rectangular black plastic key fob with a small rubber button in the centre and a tiny, tiny red LED set inside that illuminates when you press it. It operates the central locking and allows the engine to start providing you get the key in the ignition and turned within about fifteen seconds. There's a red LED on top of the dash too that flashes.

    I don't know if eBay links are allowed or not but I've found one the same as mine on eBay, item number 160454121820. According to the seller, it's a sigma type. Does that mean I can it or the car reprogrammed to sync with each other?

    Thats the sigma type fob. You've probably got the 3t-ews system. If you open the bpnnet does it say anything on the siren off the alarm?

    That fob when I needed one from the dealers was £41.17 I think plus £30 to programme it to my alarm. But it didn't work with my alarm so I just pulled the whole thing out. This was on a e36 though so it didn't immobilise the car as the immobiliser is built into the transponder key.

    If I was you I'd buy the fob new that way its bmw's responsibilty if they can't programme it, they never charged me for the fob or the time they spent to get it working. Problem your gonna have is there going to need the car at their place or if you could try your local lock smith or auto lock smith to come out to you it could work out cheaper
