Sorry Gang for digging up a old thread, instead of starting a duplicate one.
I usually Purchase New OEM Fobs, and recommend New Key Fobs, as I recon they are the best replacements,
but have you seen the prices of the OEM Key Fobs now probably because "Holden has left the Building" !
the last OEM ones I purchased were $49, the Same Key Fob is now $89+
My recent purchase a car with Original 2 Keys, [I didnt expect them to work due to the age]
One was ok, the other had worn out buttons,
But they "both" only worked while close to the car, or in the car.
however, my recent Car I purchased (2006 VZ Adventra - My Project) I am on budget the moment due to now work.
So I figured,
Ahh, the internal Batteries were going flat,
I found a guy that is local to me that sells the CR2032 Tab Batteries for $2 online,
So I organised to meet him and purchase the 2 Batteries.
Today my mission impossible, was to replace the Batteries in both remotes,
Split the shells open,
de-soldered the both batteries with a solder sucker,
Installed the replacement Batteries,
Glued the shells back together with Epoxy Resin glue,
And they went back together and look as good as new, very pleased with the result !
but,
The same operation remains, I have to be close to the Car, or inside the Car for them to work.
So I have put it down to the Common Denominator, it has to be the Receiver or similar.
Has any other Member/s had the same issue with a Lack of Range with the Key Fobs/Heads ?
If so, how did you over come it ?
I disconnected the Car Battery for 10 minutes,
Did the Key/Ignition Re-set thing,
but still the same issue.
Is there a Physical Receiver, if so where is the Reciever for the Remotes,
or is it built in to the BCM.
For the Programming of the Key Fobs, it is a Seperate Menu on the Autel.
Any input will be appreciated.
