Can't get Blazer into transmitter programming mode

Transmitter Programming
Important: All transmitters which are to be recognized by the remote control door lock receiver (RCDLR) must be programmed in a single programming sequence. If the system is placed in program mode it will erase all previously programmed transmitters upon the receipt of the programming signal from the first transmitter. Up to 4 transmitters can be programmed. Do not operate or program the transmitters in the vicinity of other vehicles that are in the keyless entry program mode. This prevents the programming of the transmitters to the incorrect vehicle.
Install a scan tool.
Use the scan tool in order to access programming: Vehicle Control System/Computer Integrating System/Module Setup/BCM/Program Key Fobs.
Press the START soft key on the scan tool.
Important: The scan tool must stay connected until all of the transmitters are programmed.
Press and hold the LOCK button and the UNLOCK button simultaneously on one transmitter. After a delay of 5-10 seconds, the scan tool will indicate that the transmitter is programmed.
Repeat the previous step in order to program up to 4 transmitters.
Remove the scan tool.
Operate the transmitter functions in order to verify correct system operation.

Here is what i found for your 95 blazer. Hope it helps a little bit.

1. Locate the red two wire programming connector located near the central
locking control module. Behind LH lower instrument panel.

2. Inside the red programming connector you will see two pins.
Jump the two pins with a section of wire. A paper clip bent in a "U" shape will also work.

3. System should now lock and unlock doors to indicate vehicle has entered
programming mode.

4. Press any button on keyless remote once. System should now lock and unlock
doors indicating the keyless remote has been programmed.

5. Repeat step 4 to program the other remote.

6. Remove jumper wire from programming connector to exit programming mode.

7. Test Remote(s).

Hi,

Thanks for using FixYa.

There isn't really much that you can do except for call the locksmith. The Chevy blazer has very good anti theft door lock mechanism. Sorry man.

I hope this helps. Have a nice day.

1. Locate the Data Link Port. It is located under dash drivers side. Be sure you know which pins are 8 and 4.

(Notice port is wider on top row)








2. Make sure there are metal contact pins in terminals 8 and 4. Connect 8 to 4 with a suitable
jumper wire (leave the jumper wire connected throughout the programming procedure). Make
sure you know which terminals are 8 and 4. The vehicle will respond by locking and unlocking the
doors to signify entering of programming mode.
3. Press and hold both the LOCK and UNLOCK buttons together on the first transmitter to be
programmed. After about 15 seconds, the vehicle will respond by locking and unlocking the doors.
Release the buttons on the transmitter.
4. Within one minute, repeat the previous step on the remaining transmitters to be programmed.
5. Remove jumper wire applied to the OBDII Port.
