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

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.

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

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
