R34 GTT Central Locking Pains

So... the fob I had for my Skyline always had this issue where the "Unlock" button worked with no issues but the "Lock" button did nothing (and I always had to lock with the key)

I thought I'd try resetting and pairing the key to the car today to see if that fixes the issue. I did the standard steps to program a key but realised my central locking was doing its own thing from time to time.

1st time:
The driver-side doors would not lock or unlock when using the fob. No issues with the key.

I figured it was the right time to change the battery in the fob so decided to go get one. When I went to the shop all doors locked and unlocked with the fob (while it had the old battery 🙃)

 

2nd time:
When I locked the car, it would lock itself and immediately unlock. If I unlocked it, it would unlock and immediately lock.

 

3rd time: 
After a bit of cursing and praying, that weird bug stopped. But then the rear passenger door started being a pain. It wouldn't really follow what the fob was asking it to do. Sometimes even using the key would not do what I wanted. So I'd lock the car with the key and all doors would lock, but the rear passenger lock didn't do anything at all. And then after a few moments, it would work again.

 

Is there a fuse that I should be looking at? or, is this one of those things where the door card needs to come off and some unit needs to be replaced? It just seems to happen from time to time and if I give her some space and come back later, there are no issues :D 🤦‍♂️
Also, should I try to program the fob again to the car just to see if that solves it?

Ok, can confirm. 
if you use it like a normal human being in the real world, it works fine. 
it only starts crossing wires if I keep using the fob over and over again in a very short period. So if I just chill the f**k out, it works 😂😂

The one door lock not working intermittently sounds odd.

But for the other issues I'd suggest to clean the contacts and everything on the little board inside the fob. I had the same issue with unlock working but not lock, and that solved it.

It brings such a quality of life change to be able to lock and unlock the car like a normal person :D

Not sure if this helps but I had a similar issue where one of the doors wouldn't lock unless I pressed the lock key twice. Turns out the door actuators were f**ked. In the Nissan service book it says to lube it every now and again, I guess put a bit a bit of wd-40. I replaced mine and haven't had a problem since.

My fob has never worked, I once attempted to follow the procedure to re-key it, (I have other fobs for the car alarm thing in there).

I actually have three of them.

Do aftermarket alarms take over the pairing mechanism for central locking? Or do they piggyback off it? I suppose it depends on the system, right?

I have four sets of keys/keyfobs. One definitely works, one I think works, one definitely doesn't work, and I have the OEM one that has never worked :p.

Is this fixable/workable/whatever? I mean I know it's beyond "just clean it" but how *do* they get synced up?

Does your door chime work when you have the key in the lock and open the door? I've had that disabled because it's f**king annoying and it is one thing that messes with the pairing. Because now the car doesn't detect key in ignition anymore and the slide-key-in-and-out sequence does not trigger the pairing mode anymore.

The service manual has a section on the various bits involved in doing the syncing. I presume it'll be similar between Stagea and R34.

What makes it worse is that Nissan made keys in the same style, for example R34 and Stagea, but they work at different frequencies or something like that. So they look the same but the remotes are not interchangeable. I learned that from some guy selling aftermarket blank keys.

Yeah - My key still does the chime thing. I followed the procedure but it didn't activate on the (identical) third set of keyfob that I had.

I vaguely remember the alarm saying you can only pair two keys with it. Now that I've dug it up, it appears that you very much can pair keyfobs to the alarm system. (which are the fobs I use to unlock the car).

I have successfully diverted the thread and can probably not use the OEM keyfob ever again unless I use the aftermarket alarm and attempt to pair the OEM keyfob to it. Which might just work, or not :D. I definitely used the nissan method and not the aftermarket alarm method.

Speaking of diverting threads, my second ever NISMO purchase…. I think they look pretty classy and just wanted to share 😅
 

PS: 1st was the oil drain plug 😂

      What brakes on R34 GTT(Europe)

      By Duncan · Posted

      Can I suggest you try EBC directly again and link them to as many competitor catalogues as you can to show their listing is incorrect, eg https://dba.com.au/product/front-4000-series-hd-brake-rotor-dba42304/ If you have access to an R33 GTST VIN and your VIN, you could also use a Nissan Parts lookup like Amayama to show them the part number is different between 33 GTST and 34 GTT which may get their attention

      So i got reply from EBC and they just this site where you can clearly see those 296mm fronts on R34 GTT. I send them photos and "quotes" that 296mm are not for 34 GTT and they are too small. But it will be very hard to return them cuz nobody here knows 100% and they just copy those EBC catalogue :-D https://ebcbrakesdirect.com/automotive/nissan/skyline-r34

      From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.

      Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.
