I recently installed a Remote keyless entry receiver in my 2000 s-10 blazer that had factory door locks but did not have factory remote keyless entry, I found many web pages that contained articles on installing a RKE receiver into a 2000 era s-10 blazer, so i followed the advice given on the web pages, installed the rke receiver up under my lower left under dash and just simply plugged it into the existing wire plug already there. Tried many times to follow key fob programming, no luck, so i searched even more. Found that it one is to install the Body Control Module from a blazer that had remote keyless entry it would already be programmed in the body control module?? One problem? When one is to install the body control module from another blazer (Passlock) shuts down the fuel pump from pumping fuel. So i went to a local GM dealer and let them install the body control module. The dumb **** erased the included program and re-entered a program for my VIN number. Stupid! Now i am right where i started from. Please!? Is there anyone that knows of this kind of installation that can please shed some light on this matter? Please!

 

What did you expect the dealership to do...? They can enable the RKE in your BCM if you were to let them know that is what you need them to do. They would simply need the VIN from a vehicle so equiped to get the proper programming and away they would go.

This thread should shed sufficient light on your situation:
How to: Keyless Entry!!

BTW, I am going to move this thread out of this very old discussion and rather link to it for reference.

 

It's all pretty simple. I did the entire job for $20-30 and 30 or so minutes of my time.

You need the BCM from a Blazer with keyless entry. You also need the airbag module from the same donor vehicle. The airbag module is under the carpet, at the rear of the center console. Swap both in. The passlock job is simple. Make sure your battery is fully charged, as you have to leave the key turned forward for about 30 minutes.

I had to crank mine multiple times before it would start. If you don't swap in the airbag module, your airbag light will be on and your airbags will not work. I've been wondering if the same thing happens when the dealership programs a new VIN(one from a truck with keyless entry) into your BCM. You get the same results. The VIN from the BCM and SDM(air bag module) do not match and will not communicate. Throws code B1001.

Now you need to program the remote(s).

 

Has anyone tried the procedure from the last poster? Do you really have to get the air bag module as well as the keyless entry module? I have only the keyless entry module from a junked 2001 Blazer to put in my 2000 Blazer that did not have locks from the factory. The key fobs match the FCC numbers on the receiver module.

 

Ok, YES, I have sucessfully installed and had activated my RKE/Alarm GM in my 2000 S-10 Blazer, I think in the end the dealership had me go get and install the Body Control Module in the parking lot at dealership, Then i had to go get the VIN number off the very vehicle the BCM and RKE came from they doownloaded the information from GM main frame? And then proceded to load it into my vehicle and WHAM!!OH!! Got IT! I love it! Its the greatest thing since sliced bread! It does exist. Not a myth.

 

On another note: I was not interested in having the alarm but it came with the Gm dealer programming? Off the 2000 S-10 Blazer LT donor vehicle from which i obtained the Remote receiver up under driver side dash, and body control module, and Vehicle Id Numbers. All i really wanted was remote keyless entry, but gained it all, now i can even pop the rear glass at my local Wal Kart.

 

How about the air bag module? Did you transfer that, too, or did your air bag warning respond properly after keyless update? How much time did the dealer take and how much did he charge?

 

Ok i am replying to this post because i was asked about the "air bag issue". From the start i never had such air bag problems or at all for that matter? No codes came up and no codes come up? Its been about 9 months now? One problem i did encounter and God love the man? Was that the dealership i chose to program my BCM and such picked the eldest man on the service team to perform my procedure. Mistake! Two times the poor man failed at programming my blazer at all. made me come back a third time and the third time they put the youngest technician on the service team and within 20 minutes the young man had not only properly programmed my BCM but had 5 key fobs programmed too for me. The dealership still only charged me the quoted price of $65.00 plus state tax? Not bad i figured? But the young man also informed me that iu should keep in my glove box a decent copy of the other donor vehicles VIN just in case my battery died or something else happened down the road? So far? So good? I love it! Now my buddy with a 2001 GMC Full size 2wd pick up that has factory power door locks wants me to help him install RKE/Alarm in his truck. Told him most of the wiring should already be there? My theory is that the wiring is there? We just need to take a day and rip apart his under dash to see?

 

Thanks for the reply. Now, I need to decide if it's worth it to have our local dealer program the car to accept the added power locks. I'd better get the BCM off the donor Blazer and VIN just in case.
