Key Fob and Sensor

[Desireless]

Hi, mum's car this time - Astra Club Estate 1.7 DTi

Despite having replaced the batteries in the fobs (spare key also),
nothing's
happening when the buttons are pressed, doors won't lock/unlock. Any ideas
please, especially where the sensor might be.

Found the answer: Put key in ignition, turn until dash lights are on, press
fob buttons and it programs it. Wuhoo!
