I have a 1997 LS Blazer and need to know how to program the keyless entry remote. I checked out the Thread on programing keyless entry systems but could not find one for my year Blazer. Any Help would be greatly appreciated. Thanks!!!!!!!!!!!!!!!!!!!!!!!! Bill

This is what I found out. Make sure you have all your remotes.
1. Locate the Data Link Port. It is located under dash driver’s 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 UNLUCK 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
