Hello,
Try resynching the fob, this should work if the battery has not been out for too long.
1, Hold both buttons down at same time, LED (on FOB) should blink away rapidly for 10-20 secs. Then take your hands off the buttons.
2, The LED on the FOB should be now on constant, simply press the big button a few times.
This should reset your FOB, if it doesnt work you'll probably need to reprogram it to your alarm.
Contact Tech-Tronics, 0161 869 0050 they are a Cobra reseller and can help with reprogramming and spares.
