central locking problems

It also wouldn't hurt to check and clean the main earths.

Has anything electrical been fitted to the vehicle around the same time the problem with the remotes started?

I have same problem. My interior LEDs are huge and been working fine for year and a half, Its not battery I know that

Well I've rulled out the lights,had them off over night and still had trouble this morning locking doors,will look at the connection on the body control module over weekend,looks like I have to pull dash out to get at it !

I'd be going down the earth road, I lot of issues occur on Patrols
because of poor earth connection. I found if it didn't work I needed to open and close driver door
Does that help at all with yours. Mine doesn't work at all now, ticked off but wt???

[tassie wombat]

So would you suggest running an extra earth cable from the battery to the chassis?ill try the door tonight.

I worked on a commodore last week that had a similar issue. After a bit of mucking around with receiver units and what not, it turned out to be a loose plug on the body control module.

Find it and remove all the plugs then re install them so they make a better contact.

Was that an early VR Commodore? they did have problems with voltage spikes causing the BCM to lock up.

Well that rules out the easy cause.

No mate it was a VT, was working fine then one day it started playing up when the weather got colder. Holden diagnosed it first as the key remote, 2x remotes later still the same fault, then then they said it was the transponder, still the same fault till we started playing with it. The BCM being a key component in the car and its age we had to rule out a dirty connection which seemed to have solved the fault but its quite possible to have a dry soldier connection on its actual mother bored like the TF Magna's security unit suffer from.

gday,ive been having trouble with the central locking on my '04 wagon,its been taking anywhere from 10 to 30 pushes on the remote button to lock the doors,so thinking it must be dodgy remotes I brought 2 new ones from Nissan at $150 each and another $55 to have them programed to suit the car.seemed ok at first(10 mins) but now its no different to the old remotes,crap,so it obviously isn't the remotes! so does anyone have any other ideas?? any help would be appreciated,thanks.

Since when did it start being that way? Did you connect any electrical or electronic gadget lately?

It is possible that the main actuator (installed in the driver's door) could be malfunctioning? Or the control unit of the remote have been misinstalled in a way that a wire is connected or tapped to a negative line instead of a positive line and the actuators were connected in reverse. At the start the connection would work okay but sooner or later it will go bad but when you install a new gadget you will soon experience the "no no".

I suggest you call an electronic technician.

This is a common problem on the U's. Scrap the POS Ni$$an locking system and put an aftermarket one in. Thats what I did and is all good now.
