xantia alarms

[john alexander]

Hi I found a 2 button plip in the scrapyard yesterday and using the forum reprogrammed the car, however when I use the deadlock button the alarm arms OK but after approx 5 mins activates,resets. It does this three times then seems to be OK. I switch it of by this time as i don't want to upset the neighbours.Can anyone help me with this ?? Regards john
