Adding new Pektron fob

I could not resist buying 2 new fobs from the MGOC.
It came in a plastic package with 2 barcodes.

For clarity, the fobs are the round ones with 3 buttons.
The label on the packaging has the SAIC logo.

Now for the stupid questions...

Can a fob use any valid barcode or does a barcode "belong" to a particular fob?

In addition, I have 2 working fobs (one for me and Mrs) and these 2 new fobs are for insurance, in case I lose a fob.

I know the EKA. Can I just go ahead and code the new fobs or do I need to recode the original fobs as well?
Slightly apprehensive....

A few separate questions there. Thanks for your patience.

Somebody more knowledgeable will hopefully be along soon, but...

I'm pretty sure that each barcode is fob specific.

There is some useful info tucked away on the pscan website .

There is also a YouTube video on programming a new Pektron fob. The YouTube link is included in the article above.

I have a fob I need to programme but, at present, my EKA code does not work. I think this is due to a fault in the door lock so I need to sort that out first. I don't dare to try reprogramming until I know that the EKA works.

Bar code is specific to a fob. It represents the window of rolling codes in which you can sync the alarm box with the fob. Once rolling code of the fob goes outside this window (you pressed fob and rolled code to another one defined number of times) you cannot sync the alarm box and fob anymore. That is the reason why Pektron fobs cannot be synced as second hand ones to another alarm box as Lucas one can.

Thank you both.
Looks like I have to make a call to the MGOC to identify which fob is linked with which barcode.

I am in the fortunate position to have read the EKA using a p-scan.

But I will not go further until the fob/barcode situation is clearer.

The code is specific to the fob, and, once the fob is linked to a car the code is no longer useful.

All the more reason that having the ability to disarm the alarm and central locking would be handy, there will come a time, probably in the not too distant future when these fobs will become unavailable.

There is a company still manufacturing Pektron fobs, at least for 433MHz markets. Australia might be a bit trickier.

Thanks for the confirmation.
I have 2 fobs and 2 barcodes but the packaging does not identify which fob is linked to which barcode
They are new and from MGOC.
Now discussing with them.
I fear that "having a go" might render both useless.

I think that if you enter one barcode and if one fob doesn't work try the other fob, that this is reasonably safe.
The fob would have to be pressed dozens of times before it rolls out of the window.

Thank you Philip.
You can see my lack of knowledge from my caution.
Now I think I get it.
"Loading" one of the 2 barcodes to the ECU through P-scan will make one of the fobs work.
All that is left is to load the other.
Makes sense. Not until the weekend though.

buy two brand new quality brand batteries for the fobs as well

Very much appreciated. I had not thought about it.
Will do.
