Fob stopped working could it be something i did ?

[Shayne]

Rewired the tow socket .
Broke reverse cam wire so had radio out of dash .
Drained 12v batteries so low they wouldn't start the truck .

New battery in the fob .

Do the fob lights work?
If they do, try pressing either button twice to re-snyc with the ECU.

 

[Shayne]

Yep , i very much doubt its the fob

 

[Towpack]

One of my fobs started playing silly buggers, sometimes it would light, sometimes not and even when it did nothing would happen. I ended up replacing the buttons and it'd been fine since. It does seem a bit of a coincidence though that it's packed up after you've been tinkering.

 

[Shayne]

I've rebuild all my fobs one way or another , because i was changing the battery i swapped the case while i was at it , bought a few original as spares long ago .

Finding that a paper punch gives you the perfect size to fit a bit of plastic inside the button rubber for better contact was a good one .

 

[Towpack]

The buttons themselves are the 4 contact type so I surmised that one or more of the contacts had turned bad.

 

[Shayne]

Yeah they do that and it can be repaired they just solder a new one onto the board

 

[Shayne]

Thinking on this while buggering about with wheel alignment , it occurs to me that locking unlocking with the key several times the past few days I have not once heard the alarm which i'm sure happened whilst doing the same in the past

 

[Shayne]

Its something in the tailgate i think , I have a door open warning flickering on the dash .

 

[Towpack]

The alarm and central locking are two entirely separate systems, the alarm having an interface that links into the CL. A door ajar will certainly prevent the alarm fob from operating the CL but the key will operate the locks as normal.
The fob sets the alarm and operates the CL so if you then open it with the key the alarm will trigger.
You can use the key for locking/unlocking as if there is no alarm fitted.

 

[Shayne]

But you cant set the alarm or lock doors when one is open surely ?

 

[Towpack]

When a door is open you can lock the other doors with the key, then when you shut the open door it slam locks but you can't do anything with the fob with a door open. At least, that's how mine works.

 

[Shayne]

Yeah thats what i meant , both fob and alarm are disabled because they think a door is open . Flickering dash warning because when i'm driving the loose connection gets rattled in and out of contact .
