(okay.. typo in subject, but editor won't let me change topic)

 

2008 GMC Sierra 1500

 

Tonight remote would not do anything (3 button). Lock / Unlock / Start

Tried spare remote.. same thing... great.

 

Used the key to unlock and drove about 20 mins. Got out and was able to lock/unlock doors with remote.

 

Came back home, remote not working again (second fob not working either).

 

Hopefully loose connection on module. However is it just one module for

keyless entry and start? If so where is it located?

 

Anything else I should be checking or trouble shooting?

 

 

Thanks in advance!

buy batteries first, spare remotes usually end up dying because they never get used. its the simplest and easiest thing to rule out completely

Okay... tried that. (Old ones showing about 3.0v, new one showing about 3.5v). Still no luck

 

BTW its a 4 button remote. Horn does not blow either. So basically nothing on either fob works. Will try readding one via DIC

 

I assume that one module controls all remote function? If so where is that hiding so I can make sure it plugged in solid. The Alldata info on this is not that great. It shows a remote entry module in drivers door, but I can't imagine that is correct in this situation considering the unit does horn and start as well.

Not sure if its fixed, or just behaving for the moment... I tried to relarn remotes via the DIC, it never chimed like it learned anything new, but now they are both working.

      The Peckish Synapse

      You're better read than that Atlas. 😏   British science fiction writer Arthur C. Clarke formulated three adages that are known as Clarke's three laws, of which the third law – that "any sufficiently advanced technology is indistinguishable from magic" – is the best known and most widely cited.   Stribeck and the pivotable Hersey Number isn't voodoo nor snake oil. That part is physics. It's what marketing and bean counters do with it that is snake oil and voodoo.    Stribeck is the relationship between Hersey and the Coefficient of Friction. Within the Hersey Equation if viscosity and viscosity is 'Dependent' on.......heat.......and.......viscosity index or the temperature to viscosity slope.    Specifically Hersey is the viscosity AT THE TEMPERATURE IN THAT LOCATION FOR THAT SLOPE.   Hydrodynamic lubrication exist when the film thickness in the location is 3X the Ra roughness of the surface. This is irrespective of the hardness of the substrate. To obtain that thickness X viscosity is required for Y velocity at Z load. That's a lot of moving parts. It is also impossible to maintain in an ICE but nearly possible with a turbine under constant load.    What does that mean? Error heavy and operate light. Wear is inevitable but the rate of wear and the milage obtainable are a function of prevailing conditions and HABITS. The only penalty is viscous drag and at fractions so low as to be well worth the effort. Double the life, half the manufacturing carbon foot print. Greed is the only impediment.    The materials generated by SwRI are the RESULT not an estimation or a hypothesis.    Don't delude yourself sir, EV's have as many pitfalls as ICE's. We just don't know what they are yet and it will take longer to sort as MARKETING and GREEDY CEO's have had more time to polish the turd they are selling.

      You can always count on greed to prey on ignorance and stupidity.    Friend bought a 2019 Ford Flex and asked me about using Valvoline R&P 5W30 in it. Told him give the miles on it and the fact it wasn't yet using oil that it was a good plan. He uses a Valvoline quick change shop for his oil service.   First they tell him that isn't the oil the OEM recommends. He told them he didn't care what the OEM thought. Then they floated the, "But it will void your warranty"    His reply was it's a 2019, there is no warranty and informed them their knowledge of the law was lacking.    Then they tell him 'But it will ruin your motor"!.    Mine to ruin he says. Finally they give in and charge him 150% the semi-syn price    Point it the brainwash is so embedded that even the service industry is drunk on their swill. The public is right behind them. Echoing the same lies on every forum and media platform. If the end goal is indeed EV then I'd say that ship is about built.
