keyless entry fob

do i have to go to the dealer to get a keyless entry fob for my 2000 blazer ls

Quick search on eBay produced this:
eBay search for '2000 Blazer fob'

You should have instructions that come with the replacement fob (if the buyer is nice) that will tell you how to get it programmed. If not, you can try to con the dealership into doing it for free saying that it just quit working and when you replaced the battery, it still didn't work.

Good Luck!

i used to work at a dealership...good luck getting it programmed for free.

Had it done numerous times (2 times on my Dodge Intrepid, 1 time for my Bonneville, and 1 time for my Bravada). All of the times, something actually happened when the batteries went dead. It did not involve replacing the fobs at all. But it was free for all of them. Bonneville has a warranty, but the Bravada did not. The Intrepid, I could do myself once I found out how to do it, but I'm not sure if that can be done with the newer vehicles. I'm sure that it can.

Ha, well, found it right in front of me... From my AllDataDIY.com account:

Programming Transmitters

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.

1. With the driver door closed, hold down the power unlock button on the door panel.
2. Turn the ignition switch to the ON position.
3. Turn the ignition switch to the OFF position.
4. Turn the ignition switch to the ON position.
5. Turn the ignition switch to the OFF position.
6. 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.

7. 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.

8. Repeat step 7 for each additional transmitter.
9. Turn the ignition switch to the ON position in order to exit the transmitter programming mode.
10. In order to reprogram the remote control door lock transmitter with a scan tool, refer to Scan Tool Instructions .

Memory Seat Recall Programming

1. Adjust the driver seat to the desired position.
2. Press the switch labeled SET. A chime confirmation will be heard.
3. Press the desired position switch labeled 1 or 2. Within 5 seconds from pressing the SET switch, a chime confirmation will be heard.
4. Press the UNLOCK button on the desired transmitter (key fob) within 5 seconds from pressing the SET switch. A chime confirmation will be heard.

o The transmitter (key fob) is now programmed with the desired position switch. Pressing the transmitter UNLOCK button will cause a recall request to be initiated and the seat will adjust to position 1 or 2.
o The stored memory positions may be changed without having to reprogram the transmitter.
o The transmitter feature is available in all ignition positions.

Memory Seat Recall Unprogramming

1. Press the switch labeled SET. A chime confirmation will be heard.
2. Press the UNLOCK button on the transmitter (key fob) within 5 seconds from pressing the SET switch.
3. Do not press any memory switch or power adjustment for 5 seconds . Pressing a switch will cancel the unprogramming event and the transmitter will remain programmed.

o The transmitter (key fob) is now unprogrammed and pressing the UNLOCK button will not effect memory seat operation.
o No chime confirmation will be heard when the UNLOCK button is pressed if the transmitter is unprogrammed.

*EDIT* fixed a weird formatting problem...

cool :D

I've got a '99 blazer that wasn't originally sold with keyless entry but I know certain vehicles have the system installed from the factory and the dealer simply sells you the fobs for an inflated cost and calls keyless entry a dealer installed option if the customer wants keyless entry. Would my Blazer fall into this category, can I just buy and program fobs or would I have to install all the wiring and whatnot for keyless entry?

If there is the wiring, you should be able to install a RKE module and then program the remotes as described above.

The RKE module is located on the hush panel above the DLC (diagnostic link connector).

If you are looking for a RKE module, you need to find an S-series blazer with the AU0 (A U zero) RPO code which can be found on the RPO listing sticker that should be located in the glovebox.

I tried doing this for my 95 blazer, but it doesn't seem to be working.

When it says put it into the ON position does that mean accessory, run or start? And putting it into the OFF position, is that then neutral position to remove the key?



I bought a new fob on ebay and asked the seller for directions. They sent me this:

PROGRAMMING

CHEVROLET

1995-1997 Blazer
1995-1997 S10 Pickup

If you have two remotes you MUST program them together or only the new one will work
Find the RED two wired programming connector located near the central locking control module behind the left hand instrument panel
Jump the programming connector terminals (which means either connect one terminal to another available one or take a small wire and touch the programming connector terminals together)
The doors will now lock/unlock to let you know that the programming has activated
Press any button on the remote one time
The doors will now lock/unlock to let you know that the remote is now programmed to your vehicle
Repeat step 5 for any additional remotes
Remove the programming connector jump lead to exit programming

Anybody ever heard of this? Otherwise, I have no idea what I'm doing wrong. I even tested the first method on another 95 with a working fob and it didn't work either.

Any ideas?

Im having the same problems. Bought the transmitters off of Ebay. It said it would work for my '01 Blazer. The only problem I have is, the parts list that normally is in the glove box is missing. Any other ways of finding out if the remotes will work with my truck. My truck does have keyless entry on it but, the remotes didnt come with it. Just the key & the valet key.  Followed the instructions that you posted Swartlkk, and still no luck.

You have to match the FFC ID code on the remote with the ID code of the RKE module under the drivers side of the dash.  

On my blazer the dealer told me even though I didn't have the RKE code, that the wiring for the transmitter was there. The problem is they were asking $100 for the transmitter, $85 for the remote and $200 worth of labor charges to install and program it. That's almost $400 just to have keyless entry. For that price I'll go ahead and used the old fashioned key and forget about it.

Sorry to bump an "old news" thread, but I figured that it was better than starting a new one.

I have the AU0 code, but do you have a picture of the location of the RKE module in a 2002? If not, what will it look like? I would like to verify the FCC code before I buy a fob on eBay.

It should be located by the OBDII port up under the panel that houses the OBDII port. This is just below the steering column on the drivers side. Should be able to remove a couple 6 point 7mm screws to remove the panel(s). The RKE mdoule should then be behind the panel.

Okay, I have the panel under the steering column removed, but what is the OBDII port?

Pictures would be awesome, if possible.

Here ya go:

Well, I found it after removing the entire lower panel. I have the KOBLEAR1XR module, so I went ahead and ordered the KOBLEAR1XT transmitter from keylessride.com. Thanks for your assistance.

Product received and programmed in a matter of seconds. What a little price to pay for such a convenience.

Hi, I have a UK specification right hand drive 99-01 chevy blazer, and have the AU3 code. I bought a new remote recently , and the programming instructions just dont work at all. It has exactly same FCC / UTA numbers as the original etc.
Does anyone have any ideas how to figure out how to get the new remote working ? I only have one original one with the car.
Thanks

What year specifically?  

Well it says 2001 on my registration document but somtimes when i put the VIN number into various sites to look up parts etc it comes up as a 1999 model - so I just cant be sure.
 
As far as I am concerned its a 2001 4.3V6 LT model, in right hand drive. VIN number being 1GNDT13W3XK192423‏
 
When I do the ON/OFF/ON/OFF routine when the door unlock button is released instead of the doors locking/unlocking a light comes on above the speedo which says "security"....I assume this means programming mode is entered...so then I hold both down the remote buttons on the original remote for 15 seconds then makes the doors lock/unlock , but try it with the new one , and nothing happens at all.....The only dealer we have for Chevrolet here is telling me it has to come in to them ,as the right hand drive chevrolet blazer has some special 5 digit code that only they know , which is tapped  in via the fog lamp button of all things ...I just find it hard to beleive that some special system was added to the right hand drive models.....
 
I have even tried some US transmitters with differnt FCC numbers, tried using the passenger door unlock button instead of the right hand drivers door, thinking maybe it is the left side that works as per the US market - all differnent things, combinations, procedures, etc etc and still no joy at all.

Anyway, any info would appreciated !

That's a new one for me man...  Let me see what I can dig up though...

*EDIT* - The only additional information that I could dig up was concerning resynchronizing the fobs...  Not sure if this has to happen after or before the fob is programmed...  This is becasue the RCDLR (remote control door lock receiver) has a rolling code function. 

quote:

Transmitter Synchronization:
* Resynchronization may be necessary due to the security method used by the remote keyless entry system.  The transmitter does not send the same signal twice to the RCDLR.
* The RCDLR will not respond to a signal that has been sent previously.  This prevents anyone from recording and playing back the signal from the transmitter.
* The panic button should still operate normally when the system is out of synchronization.
* Resynchronization may be necessary under the following conditions:
 - The battery in the transmitter is very weak
 - The battery in the transmitter was replaced
 - The battery in the vehicle has been in a low or no charge condition for an extended period of time.
* In order to resynchronize the transmitter with the RCDLR, perform the following steps:
1. Stand within 1.5 meters (5 ft) from the vehicle.
2. Simultaneously press and hold the LOCK and UNLOCK buttons on the transmitter for 7 seconds.  The door locks should cycle in order to confirm resynchronization.

I ordered form the Keyless entry that comes up on this site and i was able to reprogram my remote.  It took a couple of tries.  I had to hold the unlock button very firmly in order for it to reprogram.   It works fine.  It is a refurbish but works really well.   Came with a new battery.  
 
Funny I lost my origional Keyless entry at a friends house.   I put them on top of his frige.   Proceeded to have a couple cold ones.   They must have fell inside the freezer.  Could not find em.    
  Just got them back after 6 months in the freezer.  Lol.    He found them hidden behind some English muffins.  
Gonna try later to see if my old one still works after being in the freezer.  If so I will have 2 again.  Plus I got my Micra leaterman back and various other rod rack keys back.   No I can go back to cutting my fishing lines with a scissor and not a filet knife.  
Yee haw.    Do you think it is gonna work after 6 months in the freezer?
  LMAO.   
 
 

Shouldn''t be a problem.  Glad you got it all sorted out.
