Common issue in the winter month is the Cobra Alarm on the S1 becoming unsync’d with the key fob if the battery runs flat. The procedure to reset the alarm / fob is as follows;
– Stand close to the car and hold down both buttons on the transmitter until the LED on the fob is extinguished (approx. 10 seconds).
– Release both buttons; the fob tell tale should come on constantly.
– Press the larger button for one second (the fob tell tale will flash)
Synchronisation is complete.
