Thread: D2 Immobilizer and external radio interference

Did you happen to park in front of, or near a Chemist Shop?

I have read where their computer/cash register terminals can cause interference.

Search on here, as it's been covered a few times.

I've read about this in P38 rangies:

A quick Google and I knew why I've seen it - P38arover (Ron) had a hand in it.

I had a call from a customer at 6:15 pm last Friday, he was parked at the Museum carpark and couldn't disarm the D1 at all. We had to move the vehicle away from the museum 25 metres (after disconnecting the alarm sounder) and then it would work. Infra red motion detctors etc are my guess. There has also been instances where vehicles had to be towed off Mount Wellington because of radio interference fromthe broadcasting towers up there...Modern electronics, don't you love 'em.

Yep, usually caused by radio masts. The main culprit is usually mobile phone masts.

I had the same problem in 2 areas within close proximity to my house. I had to call roadside assist in one instance. We rolled the Disco back 6 metres & bingo. No problem. Later on when I scanned the area I located several unsecured wireless networks. Needless to say once I started logging on to these unsecured networks they were secured & I never had the problem again. Maybe there was a wireless network connection in the area you were in that caused microwave interference.

Hi, it's the signal given out by scanners in shops, I also have a D2 and it's happened many times, there is no fix until retailing equipment Manufacturers get together with the car industry and sort out signal codes. It's not just the D2, there's other makes involved. For future reference:
when parking and setting alarm, if it doesn't lock straight away, look around, there's probably a chemist, park elsewhere.
If you do get stuck, walk around the car at varying distances trying to unlock with remote
push car about 6-10 feet it will probably start then
go into chemist and ask for the scanners to be turned off for a minute so you can start your car

Let me guess - there was an Amcal chemist at that centre....their scanners interfere with the cars computer - the imobilisation aspect of the security system. LR know about it but wont admit it until you push them. There is a fix - to go back to D1 Mhz transponder. I pushed them out of warranty (because its got nothing to do with the age of the vehicle) and they agreed to fit a whole new receiver and key pads - $3000 worth - free. In effect they change the frequency on which the key pads run. I think before the change they were 200mhz or so from memory.

Hit them up....tell them they have done it before out of warranty for free.

EDIT - its not perfect because the D1 had the odd interference problem, but its a lot better than the D2 standard frequency
