1999 Chevrolet Blazer Lt Keyless Entry Remote Programming

[yorgee]

I have trouble programming the remote of the keyless entry. The vehicle has one factory remote which doesn't work every time but i can still lock/unlock. I recently bought second remote as spare in case factory remote fails. The trouble is that the vehicle won't go in programming mode. I got the instructions from the seller of the remote but it didn't work. I tried at least 20 times and nothing. I decided to try with fused jumper wire between 4 and 8 pin of Data Link Communications Connector - unfortunately the connector doesn't have 8-th pin.

 

Any help or advice regarding this issue is highly appreciated.

what instructions do you have?

Bellow are the instructions I have from the ebay seller:

 

 

1. Close all doors

 

2. Insert key into ignition

 

3. Hold down the power UNLOCK button on the driver's door panel, continue to hold down

until instructed to release in step 9.

 

4. Perform steps 5 through 8 in a fairly rapid succession.

 

5. Turn the ignition to the ON position (as far as you can go without starting the engine.)

 

6. Turn the ignition to the OFF position.

 

7. Turn the ignition to the ON position (as far as you can go without starting the engine.)

 

8. Turn the ignition to the OFF position.

 

9. Release the power UNLOCK button on the door panel. The vehicle should respond by

door locks locking and unlocking automatically. (If locks do not cycle after you let go,

not before you let go of the unlock button, then the vehicle has not entered programming

mode and you must start procedure over. Remove key from ignition, open drivers door

and return to step 1 ). If the locks do cycle automatically then proceed to step 10.

 

10. Hold down the LOCK and UNLOCK buttons on the remote until the doors lock and

unlock. This may take up to 30 seconds.

 

11. Repeat step 10 NOW for each additional remote. (Including any existing remotes).

 

12. Turn the ignition to the ON position to exit the programming mode.

 

13. Test remote(s).
