General: 850: 850 Alarm

[k1cul]

Having issues with 850 alarm was trying to reprogram another fresher looking fob i lock the car using the working fob and I swap the battery over to other fob and as I recall I use the key to open door and alarm went off tried swapping back over no joy alarm just kept going off have tried the 5 on off to reprogram both fobs still alarm keep going off .

I have tried various combinations disconnecting battery overnight disconnecting fuses and put this one or that in first or last no joy.

When put the fuse back in the alarm light is on at the front off the dash use key lock or unlock it sets the alarm off again .

The only way I can use the car is to disconnect the fuse for centre locking .

Anyone got a other ideas or fixes to sort the issues .


Thank in advance
