    I know there are a few threads around these topics but i am getting confused with everything.

    This is my key for my 96 E36 328i Coupe:



    Reading the thread on the different alarms, i got very confused as to what i had. I've got the LED by the gearstick, but its the solid jellybean type, not the small round push button type. I haven't got movement sensors inside, but when i've jacked the car up the indicators do start flashing. I haven't found any trace of the siren anywhere and have been struggling to find the control box. I was beginning to think i just had locking with no alarm until this evening. The key has started to stop working when a button is pressed. I had to unlock with the key and the indicators started flashing as soon as i opened the door.

    Question one - I understand the coil workings inside the key, but is there a rechargable battery inside the key that can be replaced, or has it lost its code?

    Question two - If i have to replace the key, i read they are approx £30 from a dealer. Is this true because remember from working in a multimake car showroom and it costing us £70 for a key, and another £60 for coding from some dealers (of any make).

    Question three - Is it possible that i have an alarm fitted seeing as it flashes and i have the LED, but i don't have a siren attached for some reason?

    All help appreciated.

    OK, Sounds like You have had (or may still have) an alarm fitted, judging by the date probably a 3T. Interestingly you also have Radio Remote Control, usually you would have one or the other. I suspect the alarm started playing up so they took the siren out but if the indicators flash it suggests the module is still present, probably behind the glovebox. As for reprogramming the key to work the remote locking try this..

    Unfortunatly the key coding method didnt work. Either the key is dead or the module. Either could be at fault. The key is fairly battered and seen better days. If the module is behind the glovebox, i may have disturbed it when i was fiddling with the new glovebox. Keys are pretty cheap off ebay aren't they? Then i could look at the module and see if a wire has come loose.

    Check all fuses first. The key receiver is in the rear view mirror. The alarm receiver is usualy behind the glovebox. You can get a replacement key but you'll need the chip from your key to work the immobiliser transponder.

    Is the alarm receiver the black box with the yellow plug, labeled EWS LK 61. 35-8 362 277, or is this just the immobilser side of the system?

    I've answered my own question. It is that black box. After doing a continuity test, I found the LED was connected to that box.

    Problem now fixed! I found the key did have two batteries in it. Replaced those, reprogrammed using Billywhizz's info and we're all working again.

    Thanks to Billywhizz!
