Just a quick question to anyone with Sigma alarm as fitted to late classic shape UK cars, how many digits make up the pin number for the alarm ..... i've just had a spare key programmed in as the car only came with one!!! (thanks to Days of Chelmsford for their help with this as i never had the key number either) .... and the pin number that I.M. gave to Days consists of 16 digits ... seems a lot of numbers to me .... soooo, is this right amount of numbers then?

Sigma alarm has a 4 digit pin code. Check in your manual?

Sounds right for the key though as a separate item from alarm.

Yeah thats what i thought.... 4 digits for the pin .... hmmm,looks like i'll have to make another call to IM!!

Thanks Puff

The 16-digit one is most likely the alarms serial# or a seperate security code for the keyfob. In the back of my blue Sigma manual there's a silver M30 label with a 16-digit serial number on it.

The security pin for arming/disarming the alarm is defo a 4-digit job.

The documents for my car (MY99) came with two silver labels ith the pre-programmed pin on them. The Dealer kept one and I was given the other.

It should read:-

IMPORTANT
Your pre-programmed PIN is
xxxx
To change your PIN - refer to the
System Operating Instructions
S/N xxxxxxxxx - xxxxxxx

If you can't find it, thena qualified alarm installer should be able to reset the code for you.

Hope that helps some,

Stefan

Thanks stefan..... i definately never got any silver labels with the pin number on when i bought the car, MY00 ... i'll try contacting the dealer where the car was first sold, if they can't/won't help then will try an installer ..... thanks for your help mate.

I recently bought a scoob but the guy didn't know the pin number for the sigma, it is 4 digits.
I went to Lethal Alloys in Crawley 01293 427407 and the guy there 'Chris' reprogramed the keypad for me for £12.50.
You must take both keyfobs with you.

Thanks Colin ... i'll give them a call :)
