Alarm woes again

So, my key fob wouldn't turn off the alarm the other morning.



(It's a 1996 Defender 90 CSW)



Got the spare fob.



That doesn't work either...



New batteries were fitted to both fobs in June last year.



Call mechanic...



Fits new fob battery, engine starts first time, but the spare fob now doesn't work, it's buggered.



So...



I look at the workshop manual with a view to removing the alarm system and it's a monster.



Half a dozen sensors including switches, concealed induction coils and a two sensor ultrasonic alarm in the cabin, half a dozen things get switched off, the engine gets immobilised, three fuses, one of them concealed, something called the 'alarm spider' whatever that is, no real information and it talks about the 'alarm wiring harness' which all sounds horribly difficult



With one exception the only thing that's caused any problems in the twelve years I owned the car is the bloody alarm.



And it looks like getting it out/disconnected/switched off is a major task for an auto-electrician.



Is there a quick and dirty way of getting round this?

Does it have an immobilliser aspect, and if so, how's it work?

If not, then disconnect power to the alarm unit, and leave it get on with it.

If it does immobilise, you need to know how, some can be circumvented, but others can't (short of replacing the diesel pump or other hassle).

It stops the pump and the ignition circuit.

I was told on purchase that it was a Range Rover unit that was fitted as standard to the Defender CSW models as a new departure at that time by the, then new, BMW management.

Nobody seems to know if it's early enough to have a coded fuel pump.

have you tried reprogramming the key fobs Will? I downloaded the methodology off a seller on ebay if you need it. Derek

It's not that.

It's the idea that I'm using a lump of electronics that is now some twelve years old, and it can switch off my car when it feels like, and it was made by bloody Lucas...

I want it disconnected, nobody ever tries to steal the car anyway.

My mechanic says he had one similar taken out of a Discovery last year and it took about six hours, when done by a specialist auto-electrician. I was just wondering if there was a quick and dirty way of disconnecting the thing.

Defenders never had a coded fuel pump.

It takes no time at all to sort it in a Defender.... An auto electrician should sort a reliable fix in under 2 hours easily

I'm now told it can be bypassed and the alarm sounder disconnected in about double that time.
