sigma only able to program one fob
 

Hi, I have seen a lot of info on this site about sigma alarms, unfortunately I don't have a scooby I have a Mitsubishi L200, the problem I have is that since my mate borrowed the vehicle and left the lights on making the battery go flat only one of my 2 sigma fobs works, i have tried to reprogram the fobs using *17856*91*2# on the keypad but only one will work. Not sure on the alarm model the vehicle is on an S plate 1999, on the back of the fob it says "mpt 1340 wt licence exempt". I have purchased 2 other fobs off ebay 1 the same and another with "type ac 38" on the back. Any ideas will be much appreciated.

What Sigma model is it ?

Ian

I think it is the m series not sure on the model I just have an m series operating instruction book that came with the vehicle. The fob only has one button and one light if that helps.
Thanks

So you've followed these instructions?

and the LED flashed and siren beeped for each fob when pressed??

Have you replaced the battery in the non working fob??

Yeah I tried that the dash led flashes but the siren doesn't beep for the one that works, and nothing happens when I press the other fobs , as I mentioned one of the fobs I have used to work until the battery on the vehicle went flat when it stopped working. Just need to get another fob working as a spare as I don't have the pin number for the alarm.

Changing your PIN
- Arm and then Disarm the system using a working Radio Key.
- Within 30 seconds of disarming, type into the keypad: *17856*92*wxyz*wxyz# (where wxyz is your new PIN code)
- Arm the system with the Radio Key
- You should now be able to disarm the system using the new PIN code


Worth looking through Sigma Sams thread, may give an insight to your problem............
