It all started a year ago – the door locks & alarm would work normally (lock/unlock/arm/disarm) via the key fob, then, having used the fob to lock the car the alarm would randomly sound, sometimes at 3am, sometimes in the middle of the day. No pattern of weather, no evidence of attempted entry - sometimes wouldn’t play up for several weeks, then 3 times in 24 hours. Did all the simple stuff like checking the plungers, using other key fob, then got into routine of locking vehicle & drivers door via rear passenger door – fiddly but simple. THEN, 8 weeks ago key fob 1 would not open locked car at ASDA – wife unhappy at shops till Rescue man did the ‘force the key way past where you think you can’ routine. Key fob 2 had same zero effect. So now all door buttons have to be pressed up or down manually, and drivers door unlocked with key – there is no ‘open’ or ‘lock’ facility via either key fob. Boot no longer responds to either fob or button on dash; manual cable release now used for boot. Sometimes the alarm will go off as a car door is opened from outside – either fob ALWAYS turns the alarm off. What do I need, where can I get it fixed, and is diagnosis always via a Vauxhall dealer? I have trawled through loads of pages and cannot see a matching problem – there must be pcb, relay or other simple device that controls these things – all the fuses are intact under the steering column, and the engine compartment fuses seem in order, and no other equipment is ‘not functional’. The red light usually flashes in the vehicle following locking. The interior light now stays on for about 25 minutes. Please help/advise. 52 2.2 CD Auto. I like my Omega - it is the finest car I have ever had, even though it costs me - six years of costs.
