Having both fobs not working is not promising of an easy fix but check basics first.
Was the second fob known good and gets used a bit or was it most scruffy one of bunch that chucked with all spare keys and never really used.
If above is the case I would check/clean/replace Battery and try again, checking fob is actually outputting a signal be good too .
Is possible receiver on you alarm faulty or a chance something else in you location interfering with signal .
It also quite common have Battery connection issues and failed buttons on these old fob boards.
The alarm is a Sigma M30 system, they cheap to repair if you know about them so don't go throwing stupid money at it as no need .
If you do need fobs, repair service is available (services advertise on eBay etc), prices around £25 plus postage .
You can also buy a used working fob and program it to your module and swap fob board to your key housing .
Same with alarm module if was faulty you can buy this used *must be supplied with pin code or at least 1 working remote* and it can be fitted and your fobs programmed and pin also can be changed to 4 pin you prefer .
All above costs very little and we done alarm module swap and key reprogrammed for around £180 in past .
Fob issue alone could be solved for real small money .

Final option is disable it, this can be done diy and you can actually buy a plug that you put the main module harness into and you bypassed the alarm .

The M30 maunual is below which includes programming details .
Need any help post again ...

HI Buddy both keyfobs are in use  did put new batteries in both this wknd  main fob in use dose work on forth atempt . we did try to reprograme key fobs   from youtube steps

1 close all doors  lock unlock with keyfob

2put key in ignition  turn to first position

3 on /off 10 times / horn should beep once

4 open /close drivers door

5 press button on keyfob horn should sound

6remove key from ignition  horn should sound 3 times

nothing worked horn never sounded

not sure why

My OB's Sigma system alarm instructions say this:

 

 

May be worth a shot?

because it wrong procedure for Sigma system .
Follow what Greenmamba has posted as that correct and what we use .

Sounds to me like rolling code not working right so possibly might need swap out main alarm module as can't see issue with 2 known working fobs at same time.
try a relearn and perhaps a used keyfob prior to considering alarm module route .

sarga depens  wife tryed to input code on keypad to turn imob off wouldnt accept code  dont know whats going  on .  think time to get gone cut losses

[Mr B]

I would assume sigma alarm module fault, you can pick these up used for £100 range with a fob/pin code supplied and quite simply swap over and reprogram fobs and you done.
fixing it will be less of a loss than selling ...

[Ness]

daft question  where  is it. only think that looks like it is white plasit did unplug it nothing happened

[Ness]

hi all  have taken emob unit out .what a swine hidden indisde tamper proof metal box.

heres the thing why does the alarm still sound off  HELP

[Mr B]

Siren on bulkhead has a rechargeable 9v Battery inside it so can actually still sound even with car Battery disconnected and by design wired to sound siren if main harnesses tampered with/disconnected .

[Ness]

the alarm module is not a sigma m30 like me throught.  part no 88205sa000..  ctc rooo 026k  that mean anythine. have orderd a replacement

youch wood comes thursday will plug try

thanks

 guys

immo alarm module 

[Mr B]

That part of factory system that uses the transponder chip in the key which gets detected by sensor by lock barrel .
The keyfob is seperate to this and is Sigma M30 by default for EU market when your model sold here new.

To recap, you got 2 systems, standard factory that installed on production line is simple immobiliser circuit control via transponder chip built in the key .
This system did not meet EU market requirements so it gets a Sigma M30 alarm which adds siren, door/bonnet sensing, motion sensor and adds additional immobiliser and takes command of remote door locking .

[Ness]

ok thanks  will have a play this wknd when part turns up .failing that i know of a good sparky who said would come round have a go . wurst case  looking at £175 DEPENDING WHAT HE NEEDS TO DO   OUCH

[Mr B]

The part you ordered would need programming to work with your ecu and it not likely the issue .
You problem is more than likely main module of the M30 alarm .
Internal relays on boards can go bad on these and parts can be replaced from a donor board (M30 modules can be had for under £20 if have no code or remote fob with them)
A used M30 alarm supplied with pin code and/or working remote is anything between 80 and £120 pending on luck and urgency, it pretty easy plug and play to switch over (we done a lot this way as neat cost effective solution)
Last option is bypass it which quite easy and google can help, you loose remote locking and it more of a compromise result over fixing M30 system .

MR B

found sigma alarm module  behind glove box  in metal box. tryed replacement one no joy not linking to alarm ? red light wont flash

refit old one alarm goes off soon as you open door.. now then can i reset keyfobs with the sire wire left disconnected from module

[Mr B]

Did replacement sigma come with a code or working keyfob ?
did you try doing anything with pin or fob on that unit ?

I never done a relearn with siren disconnected, you can but try .
If you getting no where you going need source good working used sigma module and be sure buy one with code and/or remote fob supplied .
You can buy a bypass plug that goes into the main harness to sigma module that would bypass the sigma immobiliser and get car usable, also can google for m30 bypass wiring/instructions & get car usable while source parts or consider direction want take with final repair solution .

MR B

managed  to get alarm deactavited car fires up runs  using pincode . have tryed to reprograme keyfobs  according to sigma   instructions   . did blib to say it worked  but keyfobs still wont work. think transponder issue  not picking fobs up. 

car useable if locked unlocked with keys  pincode

 

[Mr B]

^
is this still the original sigma alarm module . the receiver and antenna are all part of main sigma alarm module .
If pincode working then does point to remote receiver issue thus good working used sigma module likely the easy and sensible cost fix .

Had anything been done to car prior to fault that likely effected it such as welding (welding voltage can damage electronics) or other work that might of damaged wiring or antenna wire off the module ?
Anything in your current location that could be interfering with fob transmission ...

[Ness]

yeah still the original one. did try the one i bought  off ebay  think its faulty the red diode light didnt light up when connected

[Ness]

bought another sigma alarm mod with pincode car fires up ok using pincode

still carnt get keyfobs to work did try setting them to new mod did blib made all the right noises . still no further forward

may need to get keyfobs checked repaired

[Mr B]

Have you tried programming just one fob ?
and if that does not work try program procedure again with other fob .
Picking up a used fob or borrowing another fob for a test would be a fairly easy way forward in diagnosis .
