Alarm issues

I have a 2003 110 which was factory fitted with an alarm/immobiliser. The alarm doesn't work and I'm not convinced the immobiliser does either. I've tried a few local alarm specialists and no one is interested in even looking. The local LR dealer wants £95 just to look, plus whatever it takes to fix it. I could get a completely new system for £299 from https://www.sasmobile.co.uk/view-category/395/CAR-ALARMS. I'm based in north Manchester and willing to travel if anyone has any good ideas?

To be honest the best alarm is going to be the factory fit, well, from an installation point of view, it's stock and ought to have less issues. I would find an independent LR garage with diagnostics and get them to interrogate the alarm system and see if it has any faults.

The alarm may not work because the siren has packed in or something pretty simple, a door switch can cause alarms not to work because the alarm ECU believes the doors are not shut etc. - can you give us some details as to why it doesn't work? What have you looked at?

£300 for a new alarm seems like the expensive option before you work out what may be wrong.

I agree it feels expensive. All the alarm does is makes a quiet ticking sound inside the vehicle. No lights flashing or siren. The immobiliser simply doesn't seem to be active. I have a landy hero in a independent garage who will tackle pretty much anything except the alarm.

Hmmm Ticking sound, like a relay - on off on off like the flashing and siren control?

Find a better Landy independent garage or go to an auto electrician is what I would say, mechanics almost always shy away from electrics, I don't blame them, because they usually don't get electrics, even electricians don't usually really get how a lot of electrical things actually work, they are very good and running in fixed wiring and switches and DB's but ask them to diagnose, find and fix an electrical fault in a light, control system or alarm system and they are just stumped.

This is why you get auto electricians, they are the real electrical guru's for cars.

If it was plugged into LR diagnostics would a 2003 era alarm show fault codes?

That's a good question re diagnostics
