Immobiliser immobilising

Can anybody advise please? My S2 has a GT 136/142 alarm and immobiliser...the immobiliser has intermittently failed to disarm, but now won't disarm at all!!. It's operated by a plastic "key", with 5 metal contacts on it, which you insert in a socket on the side of the steering column, then operation is confirmed by a series of bleeps.

Is this original Porsche fitment? Doesn't look it, as it has a red "G" on the key. Is it possible to bypass this sort of thing?

At the moment it seems I can either get an alarm specialist to come to the car, or get it trailered to Northway for them to sort out!
 
Aftermarket immobilisers are a whole world of pain. No, really. Massive hassle. A cause of less problems than car theft, but only slightly ...

The nub of the problem is usually poor fitting. Car alarm fitters are a race apart - ambitious bodge artists look to them as role models. Never choose a caar alarm by brand or model; always choose the fitter. A well-fitted alarm will give years of service, no matter what make. A good alarm fitted by your usual fitter will be hassle from the start, and probably need replacing within 3 years.

It'll be more expensive, but the trailor to Northways is the best option.

That sounds very much like my immobiler, which is a porsche fitted one and was fitted by porsche a year after production as i have the certificate. And yes they are a total pain, mine is faulty in that it runs the battery flat in about 5 days if you dont use the car. So to stop this i have to remove 1 fuse from a holder, which holds 2 fuses, which is under the drivers side dash when im not using the car, which stops the drain. While this fuse is out the car will not start, may be worth fiddling around with these to see if they do anything to help get yours started.
 
sorry you are so far away from me ..iam in lancashire and could take this off for you..and solder the loom back up and heat shrink all the wiring up..if a jobs worth doing it's worth doing right...if any body needs my help please email me..cheers carl

Thanks guys...a little sympathy does help!!

Oli: I expect you're right. Problem is this seems to be a business where people disappear on a regular basis...can't find any residual location for GT Alarms. This week's lesson: fix intermittent faults before they become permanent!!! Serves me right for not getting it seen to.

Ross: Good picture...that's exactly what I've got, so I guess it's the standard Porsche item.

Carl: Thanks for your kind offer...the internals look frightening, so I'll leave my soldering iron in the tool box!

A day on the phone tomorrow to try to find someone to come out to sort it...can't be that difficult for people who do it all the time!!
 
Graham,

The tag Ross pictured is the Hamilton & Palmer one, which was fitted to most 944's in the UK at delivery. Not a GT Alarms one. But that's a bit irrelevant as they all work the same way, and all cause the same problems when they pack up.

Taking it off the car is the best bet. I'm not about to post too many details about how to do that on an open forum for obvious reasons, but if you are handy with a multimeter and soldering iron then you will be able to do it without too much problem. (If you aren't then you shouldn't be attempting it!)

If you would rather not go there or simply don't have the time then find a GOOD local installer and ask them to do the necessary. Ask for recommendations - perhaps your local PCGB/TiPEC region knows of someone who is worth talking to.

Watch the insurance situation - you may well find that you need to have an immobiliser fitted for your insurance to be valid.

Had a similar looking key for the immobiliser on my car. Similar fault too which also got gradually worse. I found that a good wiggle of the key would work for a while. I figured that it was a contact problem.
Don't know if it's worth giving yours a good clean and a wiggle when you use it?
[:D][:D]
I now have an Avital alarm which operates the central locking. Other than being a bit nervous it works fine.
 
Thanks Ian.

Latest is I've got the RAC looking at it right now, in the expectation that our "Home Start" cover will get the car recovered to Northway tomorrow where the offending bits would be replaced. It's a bit far, apparently so I might have to look at one of the indies closer to me...
 
hi graham don't think the rac will sort it mate.but it would be nice if he can..its a shame you are miles from me..i could sort it in about a hour..and you would'nt know i've been there..hope you sort it out graham..please let me know how you get on..and what you get charged...carl
 
RAC probably won't sort it, but if they don't then they will tow it to somewhere which might ... which is Northway (as Graham said!)

Good idea Graham. I wouldn't have thought of that. Hope they decide the distance is OK after all.

A happy ending (sort of):

You were all right, the RAC couldn't sort it (didn't expect them to, but to be fair he gave it a damn good go).

Local alarm specialist alarmed me when they said they'd need to take the seats out just to disconnect the immobliser...2 - 3 hrs labour(incorrect: Northway thought they were confusing it with Carrera 3.2). I'd still have had to get an immobiliser refitted.

So I bit the bullet and decided to get the car taken to Northway...a good decision...they know what they're doing and it was roughly £30 parts/£30 labour (at their competitive rates just over half an hour!!)...just fitted a new 5 pin receptor on the steeing column. A good outcome, then...proves it's worth taking the car to a specialist!

The only bad news? Well I wish it had packed up while I was out somewhere...RAC Home Start will only take you 10mls which doesn't get me to any of my local indies, so I had to pay the going rate for the flat bed. Don't ask.....

Oh very good Graham! I do like small jokes like that! I see what you did there - ha ha ha !

<SarkModeOff>

While it doesn't take that long to take the seats out (10 mins is nearer the mark), the idea perhaps wasn't as daft as it sounded as it is sometimes necessary when doing that job. But I'll say no more.

If the recepticle on the steering column was the problem then replacing it is certainly the solution. Glad all is now well.
