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 remote control door lock receiver (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:
Stand within 1.5 meters (5 ft) from the vehicle.
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.

Even though the document says 2000 model, the procedure is the same for the 2001.

Transmitter Programming

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 S/T pickups and utilities, use a transmitter identified with GM/UTA preceding the part number.


With the driver door closed, hold down the power unlock button on the door panel.
Turn the ignition switch to the ON position.
Turn the ignition switch to the OFF position.
Turn the ignition switch to the ON position.
Turn the ignition switch to the OFF position.
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:
Locking the doors
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.


Hold down the lock and unlock buttons on the transmitter until the remote control door lock receiver will respond in the following manner:
Locking the doors.
Unlocking the doors.
Repeat step 7 for each additional transmitter.
Turn the ignition switch to the ON position in order to exit the transmitter programming mode.
In order to reprogram the remote control door lock transmitter with a scan tool, refer to Scan Tool instructions.
Memory Seat Recall Programming
Adjust the driver seat to the desired position.
Press the switch labeled SET. A chime confirmation will be heard.
Press the desired position switch labeled 1 or 2. Within 5 seconds from pressing the SET switch, a chime confirmation will be heard.
Press the UNLOCK button on the desired transmitter (key fob) within 5 seconds from pressing the SET switch. A chime confirmation will be heard.
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.
The stored memory positions may be changed without having to reprogram the transmitter.
The transmitter feature is available in all ignition positions.
Memory Seat Recall Unprogramming
Press the switch labeled SET. A chime confirmation will be heard.
Press the UNLOCK button on the transmitter (key fob) within 5 seconds from pressing the SET switch.
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.
The transmitter (key fob) is now unprogrammed and pressing the UNLOCK button will not effect memory seat operation.
No chime confirmation will be heard when the UNLOCK button is pressed if the transmitter is unprogrammed.

The programming procedure must be done if you are adding, replacing transmitters or the synchronization procedure doesn't work.

I checked the dealer and they were about $45. I just bought one off ebay for $12. I know I'm taking my chances though!

Gmmmerlin,
Do you know if the 2002 Blazer uses the same procedure? I have searched all the forums and cannot find a reference for 2002 model year. The dealer says they have to do it.

I have a 2002 Blazer and have purchased 2 extra remotes from e-bay and was able to program then using the above listed procedure.

I have a keyless remote with part number 12490830 for a 2001 Blazer Extreme (S-10) that I cannot get programmed using the above instructions. Can anyone point me in the right direction regarding programming this keyless remote.

I recently went over a similar on this thread http://www.automotiveforums.com/vbul...light=vsc+3000

I believe you have a GM aftermarket security device installed. Remote transmitter #12490830 is same as mine for the VSC 3000 unit.

Check your PM for the procedure.
