I have a factory fitted Sigma immobilser alarm fitted on my 52 plate STI.

I travelled 160 miles yesterday to stay in Hastings with my lady got there and everything was fine.
Theres no masts near here house just a telephone line 15 metres away.
After 30 mins at her house her mum wanted to get her car out to go to Tescos so I try to unlock the car and nothing.
Unlocked it with the key and the alarm went off and I obvioously couldnt disarm the immobiliser as I didnt know the Keycode for the keypad at the right hand side of the steering wheel.

I tried ringing the garage I got the car from and the immobilser wasnt registered therefore they didnt have the code.

I was completely screwed as her mum needed to go to hospital in the morning at 5am so I was buggered had to move the car but was on a stupidly steep hill.

RAC turned up and couldnt disarm the immobiliser to start the car.

Im still majorly pissed off and had to come home last night on a 4 hour trip in a smelly recovery truck with the alarm going off every 10 seconds on the way back.

I cant even start it now to get the thing to the Subaru garage.
Im so annoyed at not seeing my girlfriend.

I really need the code but havent had any luck from Sigma.

GRRRRRRRRRRRRRRRRRR SO MAD!

Stupid Subaru immobiliser what a pile of ****.

 

It's a common problem with the Sigma alarms. Best bet is to have it removed and have something else installed.

 

have you had any symptoms on the run up to this at all?
Only my led has stopped working at all but all the system still works.

 

LED still worked.
I tried a spare key today and it freakily worked. Locked the car again to go inside then didnt work. Tried it a few hours later worked and took it straight to Subaru garage. They reset it with the overide code but couldnt re program a 4 digit pass code.
Its booked in next week to rip the stupid immobilser out.
Had the car since 2002 and no problem what so ever.
