I have recently purchased a new key fob and need to find the programming instructions. My dad told me how to program one for a Silverado but when I followed those directions it would not accept the new programming. The registration number on the back of the key fob says GM/LEAR 25695955, FCC ID: KOBLEAR1XT. This key fob was reported to work on the 2001 Jimmy's any help would be greatly appreciated, thank you.

You had one fob already and got another one, right? Match the numbers on the one you had to the one you got. If you didn't have one already, the truck may not have RKE, so programming the remote isn't all you'll need to do.

 

Here is the programming method for a 2001 Jimmy 4WD:

 

1. Get in truck and close all doors

2. Put key in ignition

3. Press and hold the door unlock switch

4. While holding door unlock swich, cycle ignition 2 times, ON-OFF-ON-OFF

5. Release the door unlock switch, the door locks should lock and unlock to confirm the programming mode

6. Press and hold the LOCK and UNLOCK buttons simultaneously on one transmitter. After a delay of approximately 15 seconds the doors will lock and unlock to confirm the programming of that transmitter

7. Repeat step 6 for each additional transmitter (up to 4), including any you had before.

8. Turn key to RUN to exit programming mode.

9. Operate the transmitter functions to ensure correct system operation.

 

This is directly from my GM service manual on CD...

 

Went back and looked, it's the same procedure as for a 2001 Sierra 4WD, so your truck may not have the RKE module to accept the programming or your transmitter may be wrong. Look in your glovebox for codes AU0 or UA6, this will tell you if you have either of 2 RKE systems.

 

The AU0 system will work with a transmitter that has the padlock symbols on it or one that spells out Lock and Unlock on the buttons, both have buttons for the rear hatch. The UA6 system only works with the transmitter that spells out Lock and Unlock on the buttons. I can't help you to verify you have the correct transmitter for your vehicle, beyond what I've described above.

      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.
