Land Rover Repair: Discovery I Alarm, degs c, bad moods


Question
I have just read that you say you know  how to disable the alarm. So do I, that s not a big deal, but the question is: with a disabled alarm will the car start.
I have the problem of occasional non functional fob. And if I cannot open the car with the handheld I cannot start the engine. I can disable the alarm with the KEA (door code) but still the car will not start.
here is what i previously wrote:


Intermittant failure opening the doors and start the engine I do have a challenge to you all.  The Landrover workshop guys have not been able to solve the problem: So now it is up to you, please.
I have a 1996 Disco I
The handsett (fob) usually works perfect, but then suddenly, when parking trying to lock the doors or when trying to open the doors after parking, the fobs does not work.
I can open the doors with the door code but I cannot start the engine because the immobilizer has not got the right info from the theft alarm.
After moving the car or after waiting suddenly it does start again, and may work without problems for days. parking in the same spot is no problem (i.e.: no interference from radio transmissions) And then normally under the worst conditions (full car going on holiday or in cats-and-dogs rain it does not work.

The LR guys have tried replacing the radio receiver part, the fobs, almost everything  Nothing works - until the Disco decides to be kind again.  It has by now spent almost three months in the workshop.

So it is not interference, it is not week batteries in the fobs.
Sometimes (but could be coincidal) it happend more often in burning sun (I am speaking about 30 degs C pluss) or in wet weather.

I have given up as have the LR guys.
But I think it should be possible to  ground the starting solenoid and bypass the blocking of the fuel pump, so I could start the Disco when it is in bad moods. But how?
No, i do not want anyone to give an answer in the forum, but if there is anyone out there that knows the answer I beg you to give the answer to my workshop guys so they can implement it.

As it is I do not dear to use the car becasue suddenly i am stranded in nowhere.

Please, I am on the verge of crying........
Thanks.

Answers I have got indicate all a psider problem BUT as far as I understand it is NOT the spider controlling the alarm but the other way around?

Answer
Hi Cato,

with an older Disco, I think it's possible to start the engine and run the vehicle without the alarm system.  From '96 on, you may have trouble as it's integrated within the engine management system. Could be possible but I'm not sure.  So many links to the immobiliser that I doubt it will go.  You'll have to bite the bullet and have your spider serviced.

Best of luck,
