Can anyone help with my alarm system. Recently bought a '96 2.0 155. When I got the car the alarm was switched off. Switched it back on and it would only work sporadically - i.e. you had to be right next to the window to get it to come on. Thought this problem may be caused by weak batteries in the remote so changed these. Now it won't work at all. Any ideas?

Cheers, Graham

Hi

Had a similiar thing with mine. First check the batteries are in the right way (not taking the p*ss, I did it wrong!!) and then clean the contacts. I think it has a spring contact, just bend that a little to make the contact stronger. Check the LED and other connections, its not unusual for hard wires to break, just soldered mine for exactly the same symptoms as you are having.

Other than that it could be that the alarm needs re-memorising for the signal. Bit of a coincidence though! Its telling that the alarm was switched off (in the glovebox?), perhaps they were having problems too before the current problem???

My alarm was disarmed on purchase and this was because the ultrasonics are dodgy, setting it off, I just turn 'em off these days with the ignition.

Had very similar experience with '96 2.0 I have just acquired. Alarm was switched off when I bought it. Had to change batteries in fob- central locking works fine but alarm works when it wants to (mostly doesn't come on actually). Perhaps there is a loose connection- any suggestions? I have also noticed a small recessed button next to the sensor in the roof- it seems to make the LED flash in different sequences each time you push it in.

Thanks Guys,

Tried to go the alternative routes - alrm installers, mobile phone specialists but eventaully had to take it to Alfa this morning. Sounds of cash registers ringing!!

They have just called to say that one of the key fobs isn't working I despite the light flashing) and it needs replaced £39! But one is working so that'll do for now.

As you may be aware Alfa charge £50 per hour!! Lets just hope it took 30 mins to find the problem. I gave them the codes it can't be that time consuming - I'll let you know.

Had noticed that recessed button next to the alarm reciever. Will ask them what it does when I collect the car.

Jsut bought some Black Speedlines from a chap who travelled up from Southport. Any recommendations for tyres - one of them not the best.

Cheers,

Graham :D

Exaclty the same problem, ultrasonics setting the alarm off and could never figure out why. Like you just turn them off with the key now but it's a pain when someone else (the other half) lends your car and she forgets to do it. There must be some common connection between the cars.

Cheers

Hi Chaps,

Well just collected car from Arnold Clark and they have fixed one key fob - recoded alarm (see below). The other one is knackered and needs replacing (£39)

In answer to earlier query re: button beside rear lamp - this is used for entering the alarm code. (Coding similar to car immobiliser code - with accelerator) Point being - don't mess with unless you have the codes for the fobs. Should have two different codes (1 for each fob).

Too my suprise - only charged £15.00 for it - should have taken it to Alfa 1st of all!! wink

Sorry, missed your earlier question about the little button. It is indeed for resetting the alarm to fobs. I've done it a couple of times and its no problem. Only had one key and the master so not sure about different codes. Only had one set of codes too! Most cars do not have the codes so you were lucky.

The procedure is, press the button until it flashes then press the corresponding number of times for each number of the code with a flash inbetween.........this is from memory!!!!

I thought I had sorted the alarm- I input the code with the small button and the alarm actvation was working (beeping and indicators flashing) but alas I have driven to work and when I locked the car the alarm didn't activate. Its as though by turning the ignition on it clears the memory or something. Am I using the right code- I used the 4 digit one that is on a credit card sized card with a key-ring in the corner.
I spoke to a FIAT garage yesterday- they wanted £25 + vat to put it on the diagnostics and reprogram the alarm, the local Alfa dealer wanted £29 + vat, but said that it might not be the problem- but wouldn't divulge further.
The FIAT garage though asked if I had the 2 metal tags with the code on (as previously mentionned I think), The only thing I can find with one of the sets of Keys is a small black plastic tag with a 6 digit number on.......HELP!!!???!!?!?!?! :confused:

My code was on a tiny scrappy bit of paper I found by accident one day!!! So can't help with identifying it beyond it being 4-digits.

It sounds like either the code was input incorrectly (possible as my instructions were from memory) or more likely that the roof receiver needs replacing as its not holding the code.

I'll check the re-programming instructions tonight when I've got more time.....

I think my 155 gets home sick. Drove back from work- alarm still not working. Had to swap positions on the drive with the punto- came to lock the 155 up - wahey alarm activated. Moved it again and it still works. Its either that it likes the diveway or likes being in the company of other Italian cars!
