Why won't my 2002 blazer go into remote programming mode?

I had two key fobs that worked intermittently at best. Tried new batteries seemed to help for short while. Finally I decided to buy one new remote. Can not get the blazer to go into programming mode, tried many times many ways! Other remotes don't work at all now either! Is it possible that the module on the blazer is bad or loose connection, blown fuse etc. Where is the module and what fuse governs its circuit.Why won't my 2002 blazer go into remote programming mode?
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.





If after you use the above steps your blazer wont enter program mode you should have the dealer check your keyless entry system.Best of luck.Why won't my 2002 blazer go into remote programming mode?
thanks, i have tried this way to program many times. I guess I will have to take it to the dealer to find the problem. Report Abuse
