Octy 2 1.4TSI ESTATE CAXA

Quite uncertain where to enter this question. The keyfob#1 has started to cause serious problems with the car alarm system. So far keyfob#2 is working with no problem. Car alarm starting randomly and only disconnecting the battery helped. Yesterday the alarm kept sounding/flashing even when the engine was running - undrivable.

Is there a home cure whereby I can remap/reset the key fob? My very helpful auto sparks is unable to help

I would suggest that your problem is not with the key fob, but with the alarm system itself - if the fob is disengaging the immobiliser to allow the engine to start, this suggests to me that the fob is working correctly.

Disconnecting the vehicle battery should not stop the alarm, as it has a self-contained, internal battery.

Thank you Warrior183.
