FOB suddenly stopped talking

[PeterAllen]

Had an unusual problem today when the car key FOB refused to activate the unlock or lock.
The FOB batteries are relatively new and the light activates when the buttons are pushed but nothing responds from the car. This has happened suddenly. Is this likely to be a fuse fault on the receiver side? or best to look elsewhere. Doors all lock and unlock centrally when done by key.

[PeterAllen]

Problem fixed by inserting key in door lock and pressing lock button on FOB whilst turning key to lock position for 3 seconds then back to upright and then removing key (lock buttoned depressed on Fob during whole process).
Apparently the Fob code can "roll out" of sync.
This process resyncs it all at least it did for me. No more key code to start the beast:D

Yep, that would have been my first suggestion.

(I have a very long list)

I've also heard that sometimes just putting the key in the ignition doesn't complete the synch, however, driving the car for 6 minutes with the key in will do it.

[PeterAllen]

Spoke to soon, The issue has occured again this morning.
Given that previously I could reset and the FOB was communicating and everything was operable, what is behind this?
Dave , what's next on your list? as when I did the driver's door lock trick this morning it didnt work. Had to do the key access code to start the car up again and now leaving the car open.
Any thoughts?

[PeterAllen]

OK have now confirmed the problem is within the FOB itself.
took rubber pad off fob and metal buttons have moved and will have to strip it down and repair the solder joint or keep the cover off and use a sharp pencil to activate the buttons:)

Did you read my post about the same lockout happening each time I park in the same Telstra Exchange. Is it happening to you in the same spot?. At least you have the access code to get it re-set

[PeterAllen]

No Wayne mine is not related to any particular parking spot. It happens everywhere and I believe it is the connections within the FOB itself.
The little metal buttons ( normally centred) in the holes have gone walkabout under the silver metal plate. I will have to pull the thing apart and hopefully reattached and secure the connections.
God knows what awaits inside and I havent a clue of how it is suppose to be done but what the hell I can always use the hammer.

DT-P38 posted a while back of a guy in the UK who will repair your old Fob.
If you are interested here is his e-mail

Problem is like many....I only have one key so sending it off is a no go.
At least I have found the little metal buttons now and have no idea how they go back on as yet as can't open the case up. Gave up last night.
I will have another go at it tonight if I get the time.

If you borrowed another car and said a prayer, I can tell you he did a wonderful job. He could probably even make you a second key.

In saying that Rupert Prior right here in Syd - AUS can probably sort you out just as well.

"Borrow another car" Never. Say three hail Mary's and hang your head in shame DT-P38

The next thing on the list is to check the drivers door lock mechanism.

I put some info in this thread which describes a preliminary check you can do.

Then, if it is still a problem you will likely need to replace the door lock mechanism, so this thread will also be helpful

Further down the list is replacing / reprogramming the BeCM !! Let's hope you don't need to go there.

Easy solution - buy another P38... when one "fails to proceed in a forward motion" you have the other to drive. From a purely practical perspective, a second P38 is a good idea as a "control" vehicle for when you are tweaking things on the primary P38.

His and Her (or me/myself) P38's sitting in the driveway is a satisfying sight :D

[PeterAllen]

Thanks Dave, all locks are good. Its the key fob which is the problem as posted earlier. Will conatct Rupert and see if he does repairs or can replace.

[ROLO]

Did you have any luck contacting the local guy, Rupert Prior, do you have any contact details. I'm suddenly started having a similar issue.

mY fob close the door but will not open it, I have to use the key manually in the lock. The red light does not come on when trying to open. Similarly, I only have one key. Haven't neede a code yet, but looking through the booklets that came with the RR, I don't appear to have any sort of security codes, which is a worry.

Anyhow, if you've had any success, would be interested to hear.
Cheers,
Rolo

If the light doesn't work on the fob, then it's probably a switch issue.
Pop off the button cover & you'll see the switches - see if the switch works by pressing it directly.

There's a few guys in the Sydney area who know a fair bit about these if you do get stuck.
RP as above but Mechanic2You (on here with the same name, 0419 427 162) & LAB Electronics are also clued up on these cars.

Hi Rolo,
I believe Rupert is the man in Sydney for this issue.
Our phonecalls missed each other and since been to busy to follow up.
If you take the rubber section off the FOB you may see small metal buttons that should be centred in each hole. Mine have been dislodged and therefore need to be soldered back into place.
From the look of mine they are very delicate and I am sure my two thumbs and my solder iron the size of a large screwdriver will make a mess of it.
For now I have just been using the key.
If you need assistance on this Rupert is often on this forum or at least looks on it, alternatively I can pm his number to you.

i can fix most of the issues with the remotes but water/coffee damage can be a problem. call me on 0421 509083 to arrange the details.
regards Rupert
