Help with sigma alarm key fob replacement

[220bhp]

The main key fob for my M series Sigma car imobilizer has stopped working and needs replacing.I have a spare which works,but is in bad shape to.
I have tried to change the batteries, but it still wont work,and I am worried about getting strandard in the car.How do I go about getting replacements and reprograming them.Any BTDT, or any help and advise would be much appreciated.

Do an internet check. I had a sigma once and you had to adjust a few switchs on the main control box and you could reprogram the fobs yourself.

Thanks for that. I checked Ebay, nothing at the moment.
I have been told that sigma no longer exsist, bought out by Toad,I have no idea if this is the case.
This situation must have happened to quite a few people.And given the age of the alarm,the scrap yards should be full of them,including the key fob.
I am becoming increasingly worried.

I have done an internet search today for a new key fob,with no luck. There appears to be quite a few cars with a sigma m series alarmuseing a single button fob,scubbys,bmw, and quite a few more, but the fobs are different in appearance,but the all have the same frequencey number of mpt1340.
If I buy one of these,would they be reprogrammable or not.
The key pad is on the windscreen,and I think In have the code somewhere,if I can find it.
I have one fob that needs reprogramming,but i am abit worried about doing this, incase it renders the only working fob useless.
any help would be much appreciated

Not familar with the Sigma alarm but with most of them only one key or fob is paired with the alarm. For example my alarm has two key's and two fob's but only one of each is paired, so each time the unit is reset (battery disconnected) i have to pair them with the alarm system again for them to work. So basically your dead fob might just need setup again.
