As for the key unfortunately it still won't work. :(

Silly question, the red light comes on when you push the fob button?
(battery in fob?)

Yes light comes on on both fob1 and fob2

Would getting a fault mate or similar help?

Unlikely. Do both keys fail to sync?

I'm not sure about other p38ers but I have had my battery disconnected numerous times and never had the re-sync problems.

I did at one stage have a low battery in the remote, the only way I could get into the car was to hold the fob close by the receiver (near the petrol filler cap), it could be worth a try?

What year is your Rangie?

I had to sync my second fob before my recent cape York trip (Bosch HSE) and the ol' key in the door, turn to lock, press lock on fob, released lock button, turn to unlock, hold lock button worked for me first go.

I'd never used my second fob before then, still haven't needed to!

As for disconnecting the battery, same, I normally start with the drivers window down (unless I plan on leaving the battery disconnected overnight), car unlocked. Have never needed to re-sync when the terminals get put back on.

I am surprised at the result myself.

The car was unlocked and the battery was disconnected for a maximum of 20 mins. Whilst changing the plugs.

The beeping with all the window and sunroof faults is annoying me now.

I can live with having to use a key the old fashioned way although I would prefer the remote.

I have tried all the ways possible to re sync. I might get a fault mate or similar to see all the other errors the car has. What is the best brand and how much should I expect to pay?

Sorry the car is a 2001 THOR 4.6 HSE

That's strange hey!

I wonder if one of your battery terminals is a bit loose? Normally a healthy P38 will only become a problem child if a battery terminal is loose or the voltage is low!

Was your key out of the ignition when you disconnected the battery?

It might be worth disconnecting the battery again for 15 mins or so then reconnect, a bit like giving a computer a reboot

Thank you for all the help.

Seems like many p38s Roxy II has her own personality. After locking the car with the key as the fobs were not working. I then (a few hours later) unlocked the car with the key.... As I opened the door the alarm went off and I thought "oh no this is not good" but I then randomly pushed buttons on the fob and both fobs now work!

Another plus is all the windows except the passenger side front are now set.

She is also running better but still occasionally miss fires with the new spark plugs.
