i think i just need to manually turn off the armed alarm manually to get started on reprogrming the new fob etc does anyone know how to disarm my alarm manually that would be a great help when i got the car the alarm was dissarmed so no worrys i did the fob trick and all was brand new then i lost the keys and the fob in one go the car was at home when i lost them so two weeks later im still looking for them ive ransacked the kids the house the shed the missus the other shed everywhere to have no luck, so now ive got all the new stuff but i believe i must dissarm the alarm manually to reprogram the new stuff i have tried the battery and fuses no luck can anyone help me please
thankyou matthew
