Bought a key fob for the 2000 blazer . It does not work .

The numbers on the back are all the same as my originals .

 

Is there some kind of programing needing to be done to this ?

If so how do I go about doing it ?

Already tried changing the battery so its not that :loser:

Well of course it doesn't work. :crackup:

 

Would you want someone to be able to walk into a GM dealership, but a remote and then walk up and unlock your truck? Probably not.

 

Look in your owners manual, the procedure for programming new fobs is often in there. If not its in the FSM. Some 1996+ vehicles require a GM Tech II to program new remotes.

You don't need a tech II to do it. Hang on, let me dig through some old files and see if I can find how to do it. It is a matter of turning your key on and off a few times and then holding down the door lock.

 

I will look for it and get back to you.

Here, Give this a try. Just remember, if you have more than one Key FOB you will have to reprogram both of them at the same time, becuase when you reprogram one of them, it deactivates the other one. So you just have to do both of them at the same time.

 

1. Start with the ignition OFF, hold down the power unlock button on the door panel. Turn ignition key ON, OFF, ON, OFF. Release power unlock button on the door panel. The locks will cycle once.

2. Hold down the key FOB lock and unlock buttons for 15 seconds . The locks will again cycle once.

3. Repeat step #2 for each additional key FOB.

4. Turn the ignition on to exit the key FOB programming mode. Programming is now complete.

Let me know how you make out. If that doesn't work, I am pretty sure I have another procedure some where.

I think this is almost the same as what I just posted. But this is the actual procedure for your vehicle.

 

IMPORTANT: Different keyless entry systems are used on General Motors vehicles. The parts are not interchangeable even though the parts may appear to be similar. Observe the back of the transmitter in order to properly identify the system. On 2000 SIT pickups and utilities, use a transmitter identified with GM/UTA preceding the part number.

 

 

 

With the driver door closed, hold down the power unlock button on the door panel.

Turn the ignition switch to the ON position.

Turn the ignition switch to the OFF position.

Turn the ignition switch to the ON position.

Turn the ignition switch to the OFF position.

Release the power unlock button on the door panel. The remote control door lock receiver will respond in the following manner in order to indicate that the receiver is in the programming mode:

6.1. Locking the doors

6.2. Unlocking the doors

 

IMPORTANT: All extra transmitters must be programmed at this time. When a new transmitter is programmed, the old transmitters will be deactivated.

 

 

 

Hold down the lock and unlock buttons on the transmitter until the remote control door lock receiver will respond in the following manner:

7.1. Locking the doors.

7.2. Unlocking the doors.

 

Repeat step 7 for each additional transmitter.

Turn the ignition switch to the ON position in order to exit the transmitter programming mode.

      2027 Chevrolet Silverado: Official Discussion

      By Hdwrguy · Posted

      So after reading the reveal from Chevrolet, I kept asking myself...why did the trim levels change?   Here are the official ones:   Work Truck (WT): The quintessential fleet truck, built with durable, easy-to-clean interiors for commercial or utilitarian use. Custom: A stylish, road-oriented trim that adds a more refined appearance, standard dual exhaust, and modern exterior styling. Custom Trail Boss: An entry-level off-roader featuring a 2-inch factory suspension lift and 34-inch mud-terrain tires on a budget. Silverado: Serving as the new base consumer truck (replacing the previous LT trim), it comes standard with the Z71 off-road package when equipped with 4WD. Trail Boss: Steps up the off-road hardware with the 2-inch lift, 34-inch tires, monotube shocks, an exclusive off-road hood, and more premium interior options. ZR2: The flagship off-roader. It boasts 35-inch mud-terrain tires, Multimatic DSSV dampers, front and rear electronic lockers, forged carbon-fiber interior accents, and an available hardcore Bison Edition (co-developed with AEV). High Country: The pinnacle of luxury. It replaces bright chrome with modern satin chrome, 22-inch wheels, premium leather, real wood interior trim, a panoramic sunroof, and an exclusive front-passenger touchscreen. As others have stated, why would you want a Silverado - 'Silverado' - wth?? LT needs to remain!!!   Also, there will no longer be a dedicated Z71 model.  All 4x4 trucks will have the Z71 package. Carplay is also something that cannot be removed.  Hopefully it will remain.     I am excited about the 5.7L V8 (350 C.I.D.)  Old school Chevy power.  My only concern is whatever version of AFM/DFM cylinder deactivation.  Too bad that isn't an option a buyer can choose to have or not.   I will definitely be stopping by my local dealership when these trucks start showing up.

      OCI, not when but why?

      The not as clean as one would assume theme with the new engine oil, that reminds me of comments over the years with mechanics not always being so on board with filling an oil filter, not from the center anyway due to that typically being the clean side of the filter, danger of some contaminant falling into the filter if not careful but the realization now that the oil may not be as pure as one had assumed it would surely be. Yes it would be possible to fill from the small holes but that means messing with something to prop open the anti drain back valve if the filter is so equipped and not damage that valve in the process. Me, I have hardly ever prefilled an engine oil filter however I have prefilled diesel fuel filters with a filter on a fuel bulk tank and for anyone that has messed with diesel engines with filters and units that have a limited or no way of priming them, putting on a dry filter is a bad day to say the least with those crappy systems. But anyway back to not so clean engine oil, indeed perhaps its not so bad after all that I have not made a practice of prefilling oil filters.    As Grumpy Bear commented on keeping things clean, that I really have to wonder what the typical practice is at a dealer or any other shop that changes engine oil, do they make sure to wipe or wash off the oil plug and certainly if it fell into some gunk or onto a dirty floor, or that they wiped the filter mounting flange and didn't go and use some dirty rag and end up adding dirt to the inside of the head of the filter mount. Or be careless in how they stored or handled the new filter and if they were bumping into items under the vehicle with the filter opening facing up and having dirt drop right into the filter and if so right into the threaded center that is on the clean side. The top side, did they clean away the built up gunk that may be around the filler before removing the cap or to be really careful at that point that something right close to the filler hole that was hidden under the caps flange won't fall into the engine. Or did they clean the funnel or was that just laying there covered in oil from the oil change before and dust kicked up from sweeping the floor stuck to the oil and now that will go running into the next persons engine due to just not cleaning the funnel as "they won't know anyway" attitude as that young guy is more worried about taking a break so he can go outside and smoke a joint. Just random points that came to mind when I think about what some hired personnel may do that the shop foreman has no idea of or perhaps the whole attitude of some shops may be "eh ... who cares, they will never know the difference anyway".

      OCI, not when but why?

      By Atlas · Posted

      On the subject of OLM, Gm's OLM tool may be more "informed" than others brands. I recall OLM's in mid-2000's Chrysler products literally counting down a set number of miles. That's all the OLM appeared to be.    I would actually expect GM to be able to explain the parameters that their OLM takes into account from a high level. No, I would not expect them to disclose their software coding or data analysis around their parameters.   So we're talking about two different topics, so to continue the subject on the other one, I'd be curious to know how much "standard particulate matter" in fresh oil is able to be filtered at first start by a fresh oil filter. How much particulate matter is enough to "matter"?   I.e. how much of a "lever" do we think this equates to (variability in particulate content, in fresh oils, between different makes/brands, some which filter less, and some that filter more).   We can say that more particles = more wear = shorter engine life as a logical statement and use that data with a little marketing to scare people into selecting a more refined/filtered oil. Using a similie, is this like deciding to forego two alcoholic drinks in a lifetime because we're worried about the potential impact on lifespan? Are there numbers which translate the ISO test results into a quantifiable increase in wear for a given engine/use case?
