Sigma alarm problems..
 

Hi all, basically the alarm was working fine up until recently. What happens is when I go to unlock with the keyfob, it unlocks and disables the alarm, then locks the doors straight away.. so basically I either have to quickly open the door when it unlocks before it locks them, or if I'm not quick enough unlock it manually with the key.

Any ideas whats causing this to happen? :confused:

It's a classic UK turbo. Alarm was fitted by subaru when it was first registered.

could be faulty door motor check they both close on the buttons on doors both sides

Yep all work fine. Can't understand why it's locking the doors as soon as they've unlocked? Could it be shorting out somewhere?

Mate i had this, was faulty door lock motor as said above. The drivers side acts as a master unit for the locks.

Ah, ok... Another fun job to add to the list! Will get the door card off and have a look.

Cheers guys.

Anyone know where I can get a replacement? Tried loads of places now and no one seems to have one. Only other thing I can think is to try dealer.

eBay mate there it cheap type in door motor you will see them 2 wires about £3

Hi guys, changed the WHOLE thing and it's still doing it. Unlock, then lock straight away. Any ideas what it could be??

Sounds like the cdl switch in drivers door is not being
Triggered by the slave motor from the alarm
Undo the clamp for the alarm slave motor sit in the car and arm the alarm the motor should move and stay in the same place untill alarm is disarmed
If that works fine
Sit in car and move the door lock rod by hand until it locks car then unlock car
Once you have done this if the car locks and unlocks fine and the alarm works ok you need to adjust the alarm cdl motor untill it does what you done by hand to the car lock rod

2000 car has full cdl it is single wire operation

Just got my car back as its been in bodyshop for a few weeks. The alarm is now even worse, still got the lock bouncing issue and now the alarm is not arming/disarming properly. Which means I have to press the button about 50 times before it disarms.

Had enough of this stupid thing now, starting to drain me!

IMO get a replacement, have a toad ai606 fitted it will never let you down mate,

Yeah will be mate, just depressing me now as I've now spent £1,500 and ive only had the car 3 months! lol. new alarm and removal of old one is going to set me back nearly £300 by the looks of it.

Cheaper up here mate ;-)
